染色质凝缩-
透射电镜观察结果表明，淀粉胚乳在胚乳生长分化期的中、后期，细胞核表现典型的植物PCD的形态特征：核变形、染色质凝缩、核膜多处降解破坏，核基质外泄等。
Conventional ultrastructural observation showed that at the middle and late stage of endosperm development , several distinct morphological features of PCD had been found on the nucleus of starch endosperm , e.g. nucleus deformation , chromatin condensation , nuclear envelope disruption , and nuclear matrix leakage .

伴随胚乳的发育进程，淀粉胚乳细胞核表现出衰退特征：核变形、染色质凝缩、核膜多处被降解破坏、核基质外泄等。
Several distinct morphological features of PCD have been found in the developing starchy endosperm cells , e.g. nucleus deformation , chromatin condensation , nuclear envelope disruption , and nuclear matrix leakage .
