无性杂交为什么会迫使被教养者的遗传性发生改变,这种变化的生理基础是什么?在米丘林以及他以前的生物科学著作中没有得到明确的阐述。李森科首先提出有关这个问题的见解,他说:“必须强使接穗的枝条完全用砧木根所输送的,砧木叶所制造的可塑性物质来建造它的身体”,才能通过嫁接引起遗传性的改变。李森科在他以后的著作中不断的阐述了这种思想,并且更明确的提到砧木和接穗间所进行的新陈代谢作用便是产生无性杂种的生理基础,因此他认为只要控制了嫁接的一方去接受另一方的可塑性物质——营养,便会达到无性杂交的目的。
Why did heterosexuality force the hereditary nature of the educated to change? What is the physiological basis for such change? There is no explicit statement in Michurin and his previous bioscience writings. Lysenko first put forward his opinion on the issue, saying: “It is necessary to force the scion branches to completely build their body with the plastic material made from the stock root, which is transported by rootstocks,” in order to cause hereditary changes through grafting. In his later writings, Lysenko elaborates on this idea and mentions more clearly that the metabolic effects of rootstock and scion are the physiological basis for cloning, so he believes that as soon as the grasping party is controlled The plasticity of the other party - nutrition, will achieve the purpose of crossbreed.
