水稻成熟种子在组织培养过程中受着其所带胚乳量的影响。种子的胚乳量愈少，则始愈期愈早，愈伤组织的胚性愈强，分化率愈高；反之，种子所带的胚乳量愈多，则始愈期推迟，愈伤组织的出愈速度、早期愈伤组织生长速度愈快，但后期愈伤组织的生长速度下降得愈快，受胚乳代谢残留物质的毒害愈强，愈伤组织的分化率愈弱。这样，根据研究的需要采用不同胚乳量的种子进行组培试验，以便达到理想的试验目的。
Ripening seeds of rice are affected by the amount of endosperm they carry during tissue culture. The less the amount of seed endosperm, the earlier the beginning of the heal, the stronger the embryogenic nature of the callus, the higher the rate of differentiation. Conversely, the more endosperm the seed carries, the more the beginning of the callus is delayed and the callus The faster the callus, the faster the early callus grew, but the later the callus’s growth rate decreased more rapidly. The stronger the poisoning of the endosperm metabolized residual material, the weaker the callus’s differentiation rate. In this way, according to the research needs of different endosperm amount of seed tissue culture test, in order to achieve the desired test purposes.
