Effect of low-temperature on the forming ratio of callus of wheat green embryo
低温对诱导小麦未成熟胚愈伤组织出愈率的影响研究

The results show that the pretreatment in low -temperat ure for 6h can increase the callus formation ratio apparently,being 1.43 times h igher than that of the control;the callus forming ratio is decreased along with the prolongation of the low -temperature time,b ut the callus forming ratio increa ses after 18h low -temperature treatment.The pr etreatment of lo w -temperature for 30h can also increase the ca llus forming ratio by 1.41 times.
