在工业中工艺技术过程需要不断地进行鉴定,同样在农业中,与物候学观察的同时,也需要对作物的发育、生长和产量形成过程进行系统的生物学鉴定。现在在李森科关于生物阶段发育学说的基础上,已经令人信服地确定:一切植物都需要经过十二个发育(器官生成)阶段。现将这些阶段的简明特点引证如下:1)茎生长点未分化初期;2)茎节、节间与叶原始体的生成;3)原始花序軸的分化(穗状花序,圆锥花序,肉穗花序);4)小穗形成;5)花的形成;6)花粉开始形成;7)花粉形成结束和花序加强生长;8)禾
In the process of industrial technology requires continuous identification, also in agriculture, and phenology observations, but also the need for crop development, growth and yield of the process of systematic biological identification. Now based on Lysenko’s theory of the developmental stages of biology, it has been convincingly established that all plants need twelve stages of development (organogenesis). The concise features of these stages are quoted as follows: 1) the initial stage of undifferentiation of stem growth; 2) the generation of stem and internode and leaf primordia; 3) the differentiation of primordial inflorescences (spikes, panicles, Order); 4) spikelet formation; 5) flower formation; 6) pollen formation begins; 7) pollen formation and inflorescence strengthen; 8)
