查询词典 stratification

Seed of Podophyllum hexandrum Royle has the physiological characteristics of long dormancy and low germination in natural conditions. In order to investigate the characteristic of dormancy and find the mechanism of dormancy and the optimal method for breaking the dormancy of P.hexandrum seed, some methods such as isolated embryo cultures, biological identification, soaking seed in GA3, interaction GA3 and cold stratification were utilized.
