結論 1、本文研究了刚受精的桑蚕卵在近乎致死气溫和温湯浸渍作用下的发育变化。研究下列两种特性:(1)蚕卵对高温作用的抵抗性;(2)蚕卵在一定的影响下倾向雄核发育的能力。 2、詳細观察受精卵在人工孵化温度22—24℃中最初三小时的发育变化。这个阶段包括蚕卵成熟期和受精期。观察其分裂初期情况,一直观察到产卵后 Conclusions 1.This paper studied the developmental changes of freshly harvested silkworm eggs under near lethal temperature and warm soup dipping. The following two characteristics were studied: (1) resistance of silkworm eggs to high temperature; (2) ability of silkworm eggs to tend to develop in the nucleus under certain influence. 2, a detailed observation of fertilized eggs at artificial incubation temperature 22-24 ℃ in the first three hours of development and change. This stage includes the mature and fertilized silkworm eggs. Observed the initial split situation, has been observed after spawning
