Abstract:

Experiments were carried out in growth chamber to study the effectof low temperature(9℃ and 11℃)on pollen development,from tetradto flowering,of early maturing wheat cultivars.Fifteen cultivars of various oringin were choosen.Those cultivarsrepresented an array of genotypes showing differences in physiologicalmaturity and haveing different responses to vernalization and photoperi-od.The difference in pollen development rate among wheat cultivars und-er low temperature was prominent.At temperature of 9℃,the ...
