The formation of silique dehsicence susceptibility was investigated in terms of water content, synthetic rate of ethylene, enzyme activity of exo polygalacturonase and end cellulase , cell alteration in dehiscence zone in silique and silique dehiscence susceptibility during silique development.

从油菜角果发育过程中角果含水量、乙烯合成速率、外切 PG 酶和内切纤维素酶活性，以及角果裂区切片观察等方面研究了角果开裂敏感性形成的原因⒚花后50d 的角果果柄端壳状果瓣和线状果瓣间的裂区薄壁细胞膨大，在高倍光学显微镜下可见胞间空隙开始形成⒚此前6d 内乙烯合成速率迅速上升并出现第二次合成高峰，与之同步发生外切 PG酶和内切纤维素酶活性急剧上升，而乙烯合成第二高峰出现于角果含水量低于80％以下⒚由此看来，角果失水引起乙烯合成第二高峰出现，从而导致水解酶活性上升，最终导致果瓣裂区薄壁细胞膨大，分离和胞间空隙形成及角果开裂敏感性产生

MDA, activities of reactive-oxygen-scavenging enzymes, and change in endogenous antioxidant substances were measured respectively in Citrus guanxi-miyou hybridized and apomictic maturing fruits in the period of granulation.

以琯溪蜜柚自交果、杂交果果实汁胞为试材，测定了果实汁胞丙二醛含量、活性氧清除酶（POD、SOD、CAT）活性和内源抗氧化物质含量在果实成熟期间粒化过程中的变化。

The granulation index, MDA and activity of SOD in granulated cells were larger than in non-granulated cells; similar to POD's, SOD activity also reduced, but SOD activity in granulated cells of apomictic fruit reached bottom earlier than in non-granulated cells; GSH and ASA of non-granulated cells were higher than those of granulated cells; granulation of Citrus guanxi-miyou might related to disorder of active oxygen metabolism

SOD活性的变化趋势与POD活性相似，但自交果粒化汁胞SOD活性出现最低点时间早于未粒化汁胞；未粒化汁胞GSH 、AsA含量大于粒化汁胞。琯溪蜜柚果实汁胞粒化可能和汁胞的活性氧代谢失调有关。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
