一、幼胚培养的意义小麦幼胚培养多用于克服远缘杂交的杂交不育。小麦种、属间杂交失败的原因除受精障碍外,还因虽经受精而胚却在发育早期夭折。杂种胚早期败育一般是由于胚乳发育不正常或是杂种胚与胚乳之间生理上的不协调而引起。在胚败育之前取出培养可产生杂种植株。小麦与大麦,小麦与节节麦,小麦与黑麦, First, the significance of immature embryo culture Wheat immature embryo culture used to overcome distant hybridization of sterile. In addition to fertilizing obstacles, wheat and interspecific hybridization failed due to fertilization but the embryo died early in development. Early abortion of hybrid embryos is usually due to abnormal endosperm development or hybrid embryos and endosperm caused by physiological dissonance. Removal of embryos before embryo culture can produce hybrid plants. Wheat and barley, wheat and nodules, wheat and rye,
