With best wishes,
Botanists and researchers of this 2004 study identify fragments of gene sequencing that determine the sex for both male and female plants. They also identified certain gene fragments which may play a role in the development of hermaphrodite plants. In any case, the results of this study show that the genetics of a plant play a role in determining the sex. The commitment to a specific sex takes place as soon as the leaves of the fourth node emerge.
When humidity exceeds the optimum amount for cannabis, it is more likely that male plants will develop. In conditions with less relative humidity, it is more likely that female plants will develop.
question? when breeding for environmental condition, ie crossing sativa with indica in order to favour a northern environment, does the potency of the offspring depend upon the male, or female contributor?
The warmer the environment, the more likely it is that a male plant will develop. However, with that being said, it is possible that this stressor is linked with the photoperiod. In warmer climates, there are generally longer days and shorter nights, and the effect of temperature is inextricably linked with photoperiod.
Generally speaking, in mammals, sex is determined at birth, with no interference on physical sex by developmental conditions. For example, even under stressful circumstances, a female reproductive organ won’t turn into a male reproductive organ. However, this does occur in cannabis. Therefore, the genetic make-up of the seed cannot be the sole factor involved in determining the sex of marijuana plants.
Ultimately, any grower can force a developed female plant into being a hermaphrodite by adjusting the environment. Changes in photoperiod, increasing the temperature, harvesting too late or over-fertilizing may all result in a female plant turning into a hermaphrodite. With that said, hermaphroditism may also occur as a result of genetics, as some strains are more prone to hermaphroditism than others.
Such stress includes changes to hours of darkness during flowering, dramatic changes in temperature, drought and physical damage.
Despite having three kinds of possible seed gender, only female seeds produce buds. However, the female seeds can turn into hermaphrodites during its growth stage, especially when it experiences a lot of stress. A hermaphrodite marijuana plant means that that particular plant is both male and female. When they undergo a lot of stress, its defense mechanism in order to make sure that it survives for propagation is to turn hermaphrodite. By being both male and female, it ensures itself that it can self pollinate and therefore produce offsprings.
CANNABIS IS FROM BOTH MARS AND VENUS
However, there are other ways to find out if any of your plants are hermaphrodites. The first is to check the kind of flowers they produce. The second comes at the end of the growing process. However, it is important to check before you grow the next time. If you find seeds in your harvested bud and you know you have no males, you have a hermaphrodite plant.
Cannabis plants are not gender neutral. There are female plants, from which the actual bud flower comes. Male plants produce the pollen. However, the cannabis plant is a bit odd in this respect. Female plants can turn hermaphrodite in certain circumstances – meaning they are both male and female. This happens in a situation where the plant is highly stressed, and fears for its ongoing survival. It becomes both genders as a last resort to self-pollinate and continue to spread seeds.
Female plants take a bit longer than males to show signs of gender after flowering. The plants begin to develop a few wispy white hairs where the buds will soon grow. These flowers begin to form between the stalk and stem. Female pistils are always white (never green).
