As an experiment to study high temperature effect on pollen abortion I need to have some viable flowers to start with. I have gone for two sowing dates first week of feb and first week of March with sufficiently high temperature during these days. However I am getting only 5 to 8 % floweirng. Can foliar application of any phytohormone help?
Dear Dr. Sudershan Mishra
Flowering is fastened during the "drought-escape" mediated by ABA, which could be applied ectopically by spraying. Nevertheless, it could have side effects for your experiment.
This article provides a nice overview of its effects: Article Abscisic Acid and Flowering Regulation: Many Targets, Different Places
I hope this helps you
As teosinte is from Mexico which has relatively shorter day in summer than in the Northern hemisphere, if you are growing in a summer season in your land (Northern or Southern hemisphere) you will be having a longer day. You could probably shorten day-length by covering plant in early morning or late evening and then it should flower. To just get seeds for a crop you could also grow in greenhouse and cover in early evening to keep daylength short and it should flower.
There have always been claims from maize scientists that maize is day neutral. The claims are false. Maize is not a day‐neutral plant; it is a short‐day plant (facultative long night). When someone wants to learn whether the maize subspecies has a reaction to nightlength, suggestions are that the subspecies has no response.
