Male and female flowers in plants
Plants with female and male structures in separate flowers are considered to have imperfect flowers. Each of these monoecious plants contains both female and male flowers. The most common monoecious plants in the vegetable garden belong to the cucurbit family and include pumpkins, cucumbers, melons, and squash. Most of the flowering plants’ flowers contain both female and male organs, the female and male parts are separated in some plants, which prevent self-fertilization. Those plants can be either monoecious which means each plant has separate female and male flowers or dioecious which means each plant has only female flowers or only male flowers. To determine whether a flower is female or male, look for several key qualities. Self-pollinators (such as peas and tomatoes) have both female and male parts on the same flower. Insects or wind dislodge the pollen, which leads to fertilization within the flower.
A step by step guide to male and female flowers in plants
Some vegetable plants produce a separate male and female flower – squash, cucumbers, and pumpkins for instance. Pollination occurs when insects such as hoverflies and bees visit flowers, collecting nectar and pollen. Pollen is rubbed onto the insect and after that rubbed off onto the next flower the insect visits. Fruit will develop if male pollen has been moved into a female flower of the same species.
Male Plants – Male plants are plants that contain male flowers.
Female Plants – Female plants are plants that contain female flowers.
Male Flowers – Flowers contain a filament and an anther.
Female Flowers – Flowers contain ovary, stigma, and style.
To tell the difference between female and male flowers you will need to compare how each one looks to spot their differences. Look over the flowers of your plant to find two that don’t resemble one another physically inside of the flower. Two dissimilar flowers may be found on the same plant, or you may need to look for two individual plants to find two different ones.
Fruits form on a monoecious plant when pollen from a male flower comes into interaction with a female flower. Because a monoecious plant needs pollen transfer to produce fruits, the plant must have access to pollinators. Several pollinators visiting a single female flower result in large, well-shaped fruit. Pesticides that kill pollinators and barriers that prevent pollinators from getting into the flowers such as row covers or closed greenhouses result in plants that do not produce fruit. You can hand-pollinate monoecious plants such as cucumbers and squash in the absence of adequate pollinators. The first job in the process is to identify the male and female flowers. A female flower has a grape-sized and swelling at its base; after pollination, the swelling increases in size and develops into a fruit. A male flower has thin filaments named stamens at its center. Use a cotton swab and small paintbrush to collect pollen from the stamens, and brush the pollen into the center of female flowers.
Dioecious plants produce only female or only male flowers on a single plant. Spinach and asparagus have separate female and male plants. Some hybrid cucumbers have separate female and male plants, too. If you choose one of these varieties for your garden, plant enough seeds to obtain both female and male plants, and ensure pollen transfer between plants, either through hand-pollination or pollinators.
Pollination process in plants
The female and male parts of a plant are the key elements in pollination. The male parts include the filament and anther, which together are called the stamen. The stamen produces the pollen. The female parts are the style, the stigma, and the ovary at the base of the flower, which together is called the carpel. During pollination, the pollen grains from the stamen get stuck on the stigma, which is sticky for this very reason. Fertilization happens when the nuclei fuse with the female ovules in the ovary of the flower. These ovules grow into seeds, and the ovary grows into the fruit to protect the seed. In some plants, only one seed develops, such as a peach or an avocado. In some others, lots and lots of seeds are developed, like in tomatoes. At what time we think of pollination, we might just think of bees visiting flower after flower. But bees aren’t the only way flowers are pollinated. Let’s look at some of the other ways this can occur.
How to identify male and female flowers
Step 1) Snip off the flower, and take it to a well-lit position where it can be studied. Usually, more than a quick look is essential to tell whether a flower is female or male.
Step 2) Inspect the flower for a stamen, which is the male reproductive organ. A stamen consists of a pollen-producing anther, which is oval-shaped and often coated in white or yellow pollen. The anther is connected to the tip of the filament, which is a fine, stem-like structure that projects from the center of the flower. Together, an anther and a filament make up a single stamen, which indicates a male flower.
Step 3) Tap the flower over white paper, and look for white or yellow pollen residue on the paper. Study the flower for signs of pollen, which can be observed on the anthers. Pollen consists of the male reproductive cells and is characteristically yellow. Pollen, which is used to fertilize a female flower’s ovules, specifies a male flower.
Step 4) Examine the flower for a pistil, which has three parts: ovary, stigma, and style. Stigma is the gummy surface at the top of the pistil, and it traps pollen. The style is a tube-like structure that grows from the center of the flower and holds up the stigma. While a flower may have several stamens, flowers generally have only one pistil, which indicates a female flower.
Step 5) Check the base of the flower where it attaches to the stem. An obvious swelling in that area indicates that the flower is a female flower. Many female flowers swell at their ovary, which is a large organ in the midpoint of the flower.
List of plants with male and female flowers in vegetables
Ridge Gourd male and female flowers
Ridge gourd is an annual, climbing vine, vigorous, with yellow flowers. It may be allowed to mature, cleared of all seeds, and used as a kitchen or bath sponge, also known as a loofah. Ridge gourds produce both female and male flowers. The female flower develops into ridge gourd, and this sets them on top of their male counterparts. Identify female and male flowers on your gourd plant. Female flowers have a large, bulbous growth on the vine just beneath the blossoms, though male flowers lack this growth. Some insects and honey bees help in pollinating the flowers. Sometimes, no one of the female flowers produces fruits, but drop off without growing into a ridge gourd. This is mostly due to the failure of pollination. Although nature does its magic every day, it’s normal to go ahead and hand pollinates the ridge gourd.
Each gourd vine bears female and male flowers. The male flowers generally appear first. It is very easy to tell male from female flowers as the female flower will have the small gourd shape below the bloom, while the male flower grows on a stem without the ball shape under the flower.
Tomato male and female flowers
In case if you miss this: Hydroponic Farming Setup in India.
Tomatoes are self-pollinating, as flowers are equipped with both female and male parts. One tomato plant is capable of producing a crop of fruit on its individual, without the need for planting with another one, that means the pollen falls inside the flower to pollinate itself. That doesn’t mean wind and insects aren’t important. However, nature doesn’t always cooperate. While wind normally moves the pollen around for these plants, when there is none or when other factors, such as high temperatures and excessive moisture, poor pollination may result.
Bottle Gourd male and female flowers
Bottle Gourd has female and male flowers on the same plant. Flowers bloom in the evening and pollination occurs at night, by nocturnal pollinators. The Bottle Gourd belongs to the cucumber family Cucurbitaceae and it is a robust climber with large heart-shaped leaves. The plant bears female and male flowers on slender stalks. The female flowers are distinguished from the male by the presence of a swollen ovary at the end of the stalk. Fruits are variable in size and shape, often globular, bottle- or club-shaped that can develop to a meter long.
Bottle Gourd flowers open at night. Mainly pollination is happened by bees. Though, the male and female flowers do not always open at about the same time. Depending on the temperature, the petals of the male flowers may begin to open throughout the late evening while those of the female after dusk. In the late evenings once, male flowers are yet to open; Stingless Bees can be seen visiting the female flowers.
Alternatively, in the early mornings when the petals of the female flowers have wilted, thus avoiding access to the stigma, both Stingless and Common Honey Bees can be seen visiting the male flowers. In such a situation when female and male flowers do not open at the same time, low fruit formation is the result. By itself, hand pollination is suggested for better fruit formation, either done at night or early the next morning. The young shoots and fruits are eaten as vegetables.
Snake Gourd male and female flowers
It is also termed as serpent gourd, the rapid-growing vine of the gourd family, cultivated for its oddly shaped edible fruits. The flowers tend to be either female or male, that is, producing either ovules or pollen. The female and male flowers are found on the same plant, and obviously, this is a basic characteristic feature of the very large, diverse group belongs to the cucumber family. More exactly, our oddity is aligned with gourd-like plants, forming vigorous, high climbing vines, grabbing onto things with their slinky-like tendrils.
Snake Gourd requires insects or bees to help in the pollinating process for setting fruits. Hand pollination can be done when flowering is active during the daytime only. The male flowers are completely open before sunrise. That is the best time for hand pollination in Snake Gourd. Snake gourd wants insects to carry out the pollinating process for setting fruits. Pollination can be a problem during the rainy season since bees are less active during overcast conditions. To ensure good pollination, manual pollination can be resorted to, by pick up male flowers and transferring pollens to female flowers. Introducing beehives can do away with the essential for hand pollination.
Bitter Gourd male and female flowers
Bitter gourd can be cultivated from lowland to altitudes up to 1,000 meters. It tolerates a wide range of soil but prefers a well-drained sandy loam soil rich in organic matter. The best soil pH is 6.0–6.7, but plants tolerate alkaline soils up to pH 8.0. In bitter gourd, female and male flowers are borne separately on the same plant, and male flowers normally exceed the females by 25:1 ratio. Spraying vines with flowering hormones after they have 6 to 8 true leaves will increase the number of female flowers and can double the number of fruits.
Cucumber male and female flowers
Cucumber plants want insects, like bees, for pollination. The plant grows both female and male flowers on the same plant. While both flowers are similar in appearance and the same color. There are some variances that you can look for to help recognize which flowers are female and which are male. Inspect the Cucumber flowers and take notice of how they grow and when they open. Male flowers usually outnumber the female flowers on most varieties of cucumber plants, and they open about 10 days before the female flowers. There are so many varieties of cucumbers available that produce more female flowers, and these varieties usually produce fruit earlier than others.
Ivy gourd male and female flowers
Ivy gourd is a tropical plant in the family of Cucurbitaceae. Flowers are white, star-shaped, have 5 narrow sepals 6 to 8mm long that join at base. Male flowers of Ivy gourd have 3 convoluted stamens. Female flowers of Ivy gourd have 3 hairy stigmas. The fruit is red, ovoid to elliptical, 25 to 60mm long, 15 to 35mm in diameter, hairless, on stalks 10 to 40mm long. While ivy gourd needs cross-pollination between female and male plants, it can spread quickly and can grow up to 4 inches per day. Ivy gourd is a dioecious plant, meaning it has male flowers on one plant and female on another plant. Thus, several plants are required for fruit set, Pollinated by insects.
Eggplant male and female flowers
Eggplant does not have a female or male gender, but they are endowed with cross-pollinating male and female flowers on each Brinjal plant. Eggplants do not have a gender. Eggplant blossoms want pollination to produce an eggplant. Eggplant flowers contain both pollen-producing pollen and anthers receiving pistils, which only take a bit of air movement to move the pollen from one to the other. As stated, despite this seemingly perfect system, eggplant pollination problems may still plague the gardener. You can plant a garden that will attract pollinators, improves air circulation, or hand transfer pollen. Hand pollinating eggplant is not rocket science.
Chilli male and female flowers
The chili flower is an individual reproductive unit consisting of both female and male reproductive systems which include carpels, stamens, and an ovary. As they are self-pollinating chilies do not require the wind or insects to pollinate, though if the stamen develops and is not touching the pistil this will lead to a sterile flower. A faster way to pollinate your chili plants is to shake the whole plant. For about 3 seconds you jerk the chili stem. Vibrations are the reasons the pollen to dissolve and transfer to the same flower or other flowers.
