When pea ( Pisum sativum L.,Alaska strain) was grown in short\|day conditions,the apical bud senescence started with the transformation of the bud from vegetative to reproductive growth.DNA fragmentation was detected during the senescence using the terminal deoxynucleotidyl transferase\|mediated dUTP nick end in situ labeling method.The cell ultrastructural changes were similar to apoptosis in animal cells:the apical meristemetic cells underwent the programmed cell death.This wa...

显微、超微结构研究表明，短日照条件下豌豆顶芽的衰老过程是从营养生长锥向花芽的转化，而用DNA原位末端标记、Caspase 8WesternBlot和 14 0bpDNA片断积累的试验结果证明，转化为花芽的整个生长锥细胞发生了编程性死亡，而且其最顶端部分细胞首先发生PCD ，而顶端周围的分生组织细胞逐渐分化出花芽的各部分，但顶芽最后并没有发育成为完整的花，所有细胞就都发生PCD ，从而顶芽衰老
