Analysis and prediction on the dedifferentiation conditions of garlic 大蒜鳞芽组织脱分化条件的分析与预测

In inducing callus process , the suitable illumination conditions were the former period with darkness culture and the later period with light culture . in inducing dedifferentiation and redifferentiation process , the temperature of 24 - 26 was suitable 在愈伤组织诱导时，光照条件以前期暗培养、后期光培养为宜，在诱导脱分化和再分化时，培养条件以温度24 - 26为宜。

The tissue - localization showed that there were more silver - grains labelled in the ray , callus and regenerated differentiating vascular tissue cells than that in other tissues . it further suggested that the high concentration of endogenous iaa triggered the dedifferentiation of the immature vascular tissues after girdling , and the lower concentrated iaa flow could promote the initiation and activity of the regenerated cambium 内源iaa组织定位的结果表明射线细胞愈伤组织和新生维管组织内均有较多的银颗粒标记。这些似可表明，高浓度的内源iaa可启动未成熟维管组织细胞的脱分化，而较低浓度的内源iaa流则可诱导再生形成层的发生和活动。

Rat liver bears intensive capability of regeneration after hepatectomy inducement , which involves core problems of life science during the biology course , such as reconstructing and regeneration of mammals tissues and organs , cellular multiplication , differentiation and dedifferentiation , stress response and regulation of physiology and biochemistry 大鼠肝在经过部分肝切除诱导后具有极强的再生能力，这一生物学过程中涉及到了哺乳动物组织和器官重建、细胞增殖、分化与去分化、生理生化调控等生命科学的核心问题。

L were studied . during the meiotic process of megasporocyte , the ribosome population diminished greatly in prophase i and restored in metaphase i ; plastids and mitochondria turned unclear dedifferentiation in prophase i and recovered their normal structures redifferentiation in metaphase i . all these proved that cytoplasmic reorganization took place during the megasporogenesis of 发现了小麦大孢子母细胞减数分裂过程中，核糖体密度在前期显著降低，到中期才完全恢复质体和线粒体也出现了脱分化和再分化。从而证明了小麦的大孢子形成过程中也存在着细胞质改组现象。
