Abstract
A system of cultivation of micros-pores mechanically isolated from cereal spikes/florets (Segments of barley spikes, florets of rice and wheat) has been successfully established. A large number of green regenerats have been achieved repeatedly in two barley varieties, green plant regeneration was recovered in a wide compatible rice variety 02428. In three wheat varieties, microspore derived mul-ticellular structures (MCS) and early embryo-like structures (ELS) have been obtained. Long duration of cold pretreat-ment of spikes was beneficial to the production of ELS in barley and MCS in wheat. The efficiency of the procedure of microspore isolation, the effects of diploid tissue, air exchange condition and the advantage of early transfer of microspore derived calli to regeneration medium have been proven to improve the regeneration of green plants.
