In 1979, we reported that staminate flowers
have been induced on gynoecious lines of muskmelon by
treatment with silver nitrate (Risser & Rode, 1979). So, as in cucumber,
use of silver nitrate allows easy selfing of gynoecious lines
of melon.
Is silver nitrate having the same effect on monoecious plants? Two trials were performed in 1984: monoecious plants were sprayed with silver nitrate (500 ppm in distillate water) at various vegetative stages. In both trials, perfect flowers appeared 3 weeks after treatments and could be selfed.
So, as the allele a
does, silver nitrate induces perfect flowers in the place of female flowers whatever the allele at the other locus g that controls presence or lack of additional male flowers.
