The techniques to break dormancy and feasibility of cryopreservation were investigated using freshly collected fully mature Prunusarmeniaca seeds(true seeds + endocarp) from Xinjiang province,*** seeds germinated at the time of collection when incubated at 20/25°C for 5 *** endocarp was permeable to water,thus dormancy was not due to an impermeable coat,i.e physical *** removal of endocarps(half-seed) resulted in germination of 10% of seeds without any other *** acid treatment improved germination in 66-83% of the half-seeds and cold-wet stratification relieved dormancy in 69-80% of ***,seeds have non-deep to deep physiological *** half-seeds to water content of 3.3% *** not lead to viability loss confirming the orthodox ***-seeds dried over silica gel(4.1% Fwb.) survived better compared to air dried samples(7.8%Fwb.) following liquid nitrogen *** storing dormancy broken seeds in liquid nitrogen resulted in lesser germination percentage after 6 months of storage compared to the dormancy broken at the end of storage,this effect was not statistically significant(P> 0.05).Our results demonstrate seeds of *** can be stored in liquid nitrogen for conservation purpose.
