differentiation plantlet from callus 愈伤分化再生阶段
With this medium, soft, transparent callus can be induced from immature embryos of embryo selection or tissue and organ differentiation stages. The induction frequency was 2-6%.
以该配方诱导幼胚，处于胚胎选择阶段和组织与器官分化阶段的幼胚，能诱导出松软、晶莹透明的愈伤，诱导频率为2-6％。
The explants from immature embryo of 4 wheat varieties were cultured in vitro to study the affecting factors on callus induction and differentiation.
以4个小麦品种的幼胚为外植体，通过脱分化和再分化培养，研究了影响小麦幼胚愈伤组织诱导和再分化的因素。
In callus subculture, increase in 2, 4-d content kept the callus from differentiation, though, high concentration of 2, 4-d did harm to the callus.
在继代过程中，适当提高2,4 - D浓度可抑制愈伤的分化，但为防止高浓度2,4 - D对愈伤的伤害，分化趋势一旦控制应立即转入低浓度2,4 - D的继代培养基中。
