How to Identify Male Plants and Female Plants? 2024 Newest

Typically, we can differentiate between female and male plants by observing the preflowers that appear between the stem and petiole of the main plant. In the early stages, male pollen sacs look like a "spade", while female plant preflowers are ovate, similar to pears, and have an elongated tip.

In this article, Medic Grow will provide a detailed introduction to how to distinguish male and female plants. We will also explore how plant grow lights affect them. I hope you can maximize your planting profits by reading this.

Why Sex Plants?

This is because female plants always produce the fattest, most resinous flowers; they bud much better than males. Male plants in vegetables don't germinate well enough and don't produce enough flowers, such as cucumbers, pumpkins and watermelons.

Therefore, most breeders prefer female plants over males. Male plants are favored only for research or educational purposes.

But for the breeder whose primary motive is to produce as many flowers as possible for profit, this difference between female and male plants makes it vital to sex plants.

Another major reason why the district recognizes the sex of plants is that if male plants are bred with female plants, the male plants will affect the quality and yield of the female plants.

This is because male plants produce pollen, and when a male plant pollinates a female plant, this transfers energy into producing seeds. This process greatly reduces the ability of female plants to grow flower buds. They will still grow buds, but they won't be as large and of good enough quality.

What else?

If you are interested in hybridizing male and female potted plants, then you can crossbreed different varieties of these plants by knowing the sex of the plant.

When Does a Plant Reveal Its Sex?

Usually 3-6 weeks after the plant sprouts, early signs of pre-flowering will appear, and you can predict the sex of the plant at this point. These "pre-flowers" appear in the axils of leaves or on the main branches. Male pre-flowers are like "spades", while female ones are more pointed.

This is because both female and male plants usually go through two stages in their life cycle: the vegetative stage and the flowering stage. The vegetative stage is the first stage and generally lasts for six weeks. During this stage, they look very similar.

However, if you cannot distinguish between female and male plants at this time, then you must wait until the flowering stage. At this time, male plants produce flowers with stamens, while female plants produce protruding columns located in the center of the flower.

Male Vs. Female Plants

During the growing season, male and female plants look the same. As they enter the flowering stage, their sex begins to reveal itself; that is, as the plant grows, you will have a better idea of whether your plant is male or female.

Male plants are primarily identified by the stamen structure of their flowers, which contains the anthers and filaments responsible for producing and releasing pollen.

In contrast, the flowers of female plants usually contain the stigma and ovary structure, with the stigma located in the center of the flower and receiving pollen from male plants.

A common feature of all-female plants is that they all produce flowers. The term often used to describe these flowers is "buds". These buds contain trichomes, which are glandular structures that produce cannabinoids such as CBD and THC.

Male plants do not have this flowering trait, making them less desirable to growers who are only looking for buds.

Note that the pollen sacs of both female and male flowers grow in the same place on the plant. These two structures grow from the junction of the main stem and the branches (nodes).

Therefore, it is wise to look for pollen sacs in the same places where buds are found, even in male parts of the plant.

Tips for Growers to Identify Plant Sex

Determining the sex of a plant is quite simple; you just need to know a few basics. Female and male plants produce flowers and pre-flowers, respectively, at the junction between the branch and the main stem.

The first set of pre-flowers appear between the main plant stem and the petiole (the stem of the fan leaves), mainly at the top of the plant. Male plants tend to appear and develop earlier than female plants.

You might easily confuse stipules with pre-flowers, but here is a guide. Typically, the sexual part of the plant is located on the back of the stipules. The taller growth tips appear behind the sexual part of the bud/pre-flower.

These tips will serve as auxiliary branches that produce buds in the future.

Identifying Male Plants

In the early stages, the pollen sacs appear rounder than the pre-flowers of female plants. This feature is called "spades," and it looks like the spade suit in a deck of cards. When it starts to grow larger, the pre-flowers of male plants look like a ball attached to the end of a stick.

The pre-flowers found on the male plant part are called male flowers. These male flowers eventually grow into pollen sacs that house their genetic material. It’s best to remove male plants before they reach this stage of their development.

Identifying Female Plants

Even in the early stages, female plants have a different anatomy than male plants. They are ovate in the pre-flowering stage, looking like a pear, with an elongated tip. This structure is called the calyx.

The pistils are the white structures that extend from the tip of the calyx; they are hair-like projections that may come in pairs. It’s important to note that not all female plants will produce pistils.

At this point, you may still have some uncertainty about the sex of the plant. However, don’t rush into making a decision.

Another difference you may notice between female and male plants is that:

Male plants look more lanky than females. They have more internodes between them, maybe tall, and have fewer, narrower fan leaves. Female plants, however, appear bushier and more compact.

How Do Light Periods Affect Plants Sex?

In nature, as the days get shorter and the nights get longer, male and female plants realize that winter is approaching. At this point, they speed up budding because its life cycle in the wild is ending.

When growing plants outdoors, gardeners do not need to do anything to induce budding or flowering because the sun helps the process. Just place the plant directly in the sun so that it receives sunlight during the day and complete darkness at night.

If the plants are grown indoors, it is important to convince the plants that winter is approaching so that they can produce buds/flowers. This can be achieved by changing the plant's schedule to 12-12, i.e. the plant gets 12 hours of light and 12 hours of darkness.

If you wish to achieve the above, you will need LED grow lights and a grow tent. With these lights, you can decide how much light your plants get. You can also set different schedules through the grow light controller, and your plants will need at least 8-10 hours of light for better results.

The answer to the above question about the effect of light on plants is simple. Light cycles themselves do not affect the sex of the plant; they help reveal the sex of the plant over time.

FAQs Related to Male Plants vs Female Plants

1. What Are Unisexual Flowers Examples?

Unisexual flowers, also known as imperfect flowers, have either male or female reproductive organs, but not both. Here are some examples of unisexual flowers: Corn, Willow, Cucumber, Spinach, Holly, Papaya and Date Palm.

2. What Are Dioecious Plants?

Dioecious plants are plant species that have distinct male and female individuals, each producing only one type of reproductive organ (stamen or pistil). This means that they cannot have both reproductive organs at the same time. Examples: holly, willow, kiwi and spinach.

3. What Are the Early Signs of Male Plant?

The Early Signs of Male Plant are small, round pollen sacs (preflowers) at the nodes, a taller and robust plant structure with spaced internodes, and the absence of white pistils that female plants develop. Removing male plants promptly ensures higher yields of quality, seedless buds.
