| 摘 要： | 本文对茉莉寒害进行了解剖观察和不同覆盖物对茉莉防寒的初步研究。研究表明:受寒害的茉莉茎皮层以内的细胞,大多数原生质消失,严重的从形成层处发生断裂,使木质部与韧皮部分离,造成茎中横向运输受阻,同时皮层以内胞间隙增大和胞间隙内的物质变浓,从而可能使细胞对物质的被动转移和渗透增加,即细胞内物质外渗,引起细胞内结冰,细胞器和膜系统遭到破坏,代谢受到严重影响,因而导致细胞死亡。但加盖不同覆盖物后均对茉莉的防寒和安全越冬有良好作用,主要是使细胞内原生质浓度增加,降低了细胞的冰点,减少细胞内外结冰的可能性,使植株的器官和组织能执行正常的生理机能。

| Abstract: | Protoplasm disappeared from most of the cells under the stem epidermis of the jasmini plants (Tasininan sumbac A.t) injured by low temperature and in the case of heayier damage broking occurred in the cambium regions with separatign of the xylem from the phloem which caused damage of the meristem and block of the trangvese transportation meanwhile, the intercellular space within the corter was expanded and the juice in the space was thickned different covrings all proved having effects on protecting the plant low temperature. |
