Some growth regulators promote femaleness, while some others promote maleness. Kooner et al. (2000) reported that ethrel and MH affect growth and sex expression in bottle gourd. Rahman and Karim (1997) reported that number of female flowers, fresh weight of fruit and yield per plant were highest when a combination of 100 ppm Naphthalene acetic acid (NAA) 75 ppm; 2,3,5-triiodobenzoic acid (TIBA) and 50 ppm GA was applied. Ying et al. (1994) 3 reported that sex expression of bottle
gourd flowers can be modified by plant growth regulators. Mandal et al. (1991) sprayed the seedlings of bottle gourd with different plant growth regulators to observe their effect on sex expression. Arora et al. (1987) -1 reported that MH at 150 mg l had a profound effect on the earliest appearance of pistillate flowers at the lowest node number. Male: female -1 ratio was lowered with MH at 50 mg l and was most effective in producing the maximum number of fruits and fruit weight per plant and ultimately
the yield.

my mean, the natural hormone in plants. Equivalent to testosterone, estrogen, and ...!
You can used Gametocides as Acid gibberelic or Ethylene for killing stamens.
Polyaminez have been shown to mature Reproductive structure and gametogenesis in red macro algae in recent yeats as well....
Do you want to know if in plants you can find molecules that are similar to human hormones perhaps?
There are, however, plants that produce compounds that are estrogenic in nature. For example, Trifolium subteranneum may cause poor conception rates or abortions in sheep. But I don't believe this has anything to do with the sexuality of the actual plant, only with the animal consuming the plant.
If by "sexual" you mean that the organism produces viable organs (flowers) to produce and disperse gametes (egg and pollen)? Or, maybe you are thinking of another aspect of the effects of testosterone, estrogen, etc. on sexuality?
Plant hormones are plant growth regulators produced by the plant. Plant growth regulators are synthetic - e.g., IAA is a plant hormone, but NAA is a plant growth regulator.
In cucumber (a plant that has both male and female flowers) some hormones and plant growth regulators strongly affect the production of male (staminate) and female (pistillate) flowers. Auxins promote female flowers. Gibberellins promote male flowers. Ethylene promotes female flowers. The natural variation in male:female flower ratio and numbers may be due to variations in endogenous plant hormones.
