Effect of exogenous hormone and explants maturity on callus induction in Psathyrostachys juncea
Psathyrostachys j uncea (Russian wildrye) is a cross‐pollinated, long‐lived perennial bunchgrass, and is the only species which achieved recognition as an important forage grass in the Psathy rostachys genus( Asay.K.H.et al.1996 ).It is exceptionally cold and drought tolerant.Only 2 cultivars were released in China, both were selected from natural populations distributed in Xinjiang China.An improved new strain ( P8401) have obtained by Inner Mongolia Agric Univ.The parental germplasm was cultivar Bozoisky‐select which introduced from USDA‐ARS.FRRL.Tissues culture is the basis of somatic embryo propagation and genetic transformation in further breeding.The research aimed to discuss the effect of the sampling time of callus induction, medium screening, hormone regulation and the maturity of explants on the callus induction in Psathy rostachys juncea.
