一、柑桔类胚胎培养(一)柑桔胚胎培养1.成熟胚培养:柑桔类多数品种具有多胚性,通常珠心胚的发育优于合子胚,以致合子胚非常衰弱,难以萌发,这对有性杂交育种是一个很大的障碍,杂交后的胚数越多,合子胚受珠心胚的干扰和抑制越严重,杂种苗的获得率也就越低。对杂交后的胚进行人工培养,是提高合子胚成活率的有效措施。
First, the citrus embryo culture (a) citrus embryo culture 1. Mature embryo culture: Most varieties of citrus with more embryo, usually better than zygotic embryo embryo development, so that the zygotic embryo is very weak, difficult to germination, This is a great obstacle for sexual crossbreeding. The more embryos after hybridization, the more interference and suppression of zygotic embryos by the bead core embryos, the lower the yield of hybrid seedlings will be. Artificial cultivation of hybrid embryos is an effective measure to improve the survival rate of zygotic embryos.
