Physiological aspects of sex in angiosperms

Studies on Ambrosia. Iv. Effects of Short Photoperiod and Temperature on Sex Expression

“…However, no experiments were carried out where the control branch was defoliated. The differential acceleration of pistillate development by short photoperiod has been reported previously (e.g., Schaffner, 1927, for Zea ma.ys; Edmond, 1930, for Cucumis sativus; Kirichenko and Bassarskaj a, 1934, for Triticum erythrospermum according to Loehwing, 1938;and Naylor, 1941, for Xanthium pennsylvanicum). Sex reversal as described here for Ambrosia was primarily an after-effect of short-day treatments although there were instances within the course of the experiment.…”

Generally speaking, the changes produced in the treated branch did not appear in the other branch.…”

“…flower production is no guarantee of fruit production, flower bud is considered the better term and is used in this paper (cf. Loehwing, 1938).…”
