Hello,
I'm studying in field condition the F1 vigor of some hybrids of Maize everta in water shortage conditions.
After anthesis I noticed that some plant (without a correlation with the genotype or the treatment) and started to produce ears with masculine trait; some stamen (attached photo).
Since I used to know that usually the flower are imperfect, with ears producing only feminine trait which could be the exogenous cause of this abnormality?
Dears regards,
Ludovico Caracciolo
This hermaphrodism, or production of female flowers in the tassel, is probably a hormonal upset caused by drought. Ethylene production is triggered by a number of stresses, including drought, and etheylene is known to promote female sex expression in a number of species including corn and cucumber. I can send you some references over email if you'll send me your email address. Mine is [email protected].
