结果表明，韭型（Alliumodorum-type）胚囊大孢子发生时，自大孢子母细胞的珠孔端细胞壁内出现胼胝质荧光，并逐渐扩展到整个细胞壁，中期Ⅰ至末期Ⅰ细胞壁呈现胼胝质荧光。

The results are as follows : Allium odorum-type & Callose first occurs in the wall of megasporocyte from the micropylar end , then gradually envelops the whole cell . Megasporocyte is surrounded by the wall with callose during metaphase ⅰ, anaphase ⅰ and telephase ⅰ .

In late development stage , they have callose wall , until the cells disintegrate .

自交花粉管因胼胝质在壁上添加而停止生长。

The self-pollinated pollen tubes stopped growing as the callose added on the cell wall .

营养细胞和生殖细胞周围及其之间具有明显的胼胝质荧光。

There is obvious fluorescence of the callous around and between vegetative and generative cells .

大孢子母细胞时期细胞壁内缺少胼胝质。

The wall of the generative cell contains callose . Callose was absent at megasporocyte stage .

花粉管中胼胝质沿管壁不规则沉积，有的不形成胼胝质塞，或整个管壁被胼胝质所覆盖。

Random deposition of callose along pollen tube wall and even the whole wall was observed .

胚性愈伤组织中可观察到大量胼胝质的沉积，而非胚性愈伤组织中观察不到胼胝质的沉积。

A number of callose deposition can be observed in embryonic calli , but not in non-embryonic calli .

因此，亲和组合中胞间连丝上没有胼胝质积累从而使病毒能够进行细胞间运输。

So there was no callose deposited at PD and viruses could transport between cells in the compatible combination .

Callose exists mainly in transverse walls during dyad , triad and tetrad stages , a little in side walls .

药室内壁、中层层数增加，绒毡层细胞肥大，造孢细胞或花粉母细胞分解解体；⑤由于花粉母细胞胼胝质壁不降解而无法释放出四分体小孢子；

Cell layers of powder chamber wall and middle-level were increased , tapetum cells were hypertrophied and microsporogenesis or microspore disaggregated ;

因此，黄瓜感染病原菌后，根、叶柄内形成大量胼胝质，限制了水分运输，降低了叶片含水量和光合速率是黄瓜连作障碍的原因之一。

Therefore , the formation of callose in infected plants restrained water transport , and decreased leaf water content and photosynthesis .
