In accordance with increasing concentrations of Ca~(2+), Ca~(2+)-ATPase and H~+-ATPase activity in plasma membrane and tonoplast of cucumber root were increased significantly at first, then decreased slightly later; H~+-ATPase activity in plasma membrane and tonoplast of cucumber leaf was changed unremarkably; Ca~(2+)-ATPase activity in plasma membrane and tonoplast of cucumber leaf was increased significantly at first, then decreased slightly later.

低温下，随Ca~(2+)浓度的升高根中质膜和液泡膜Ca~(2+)-ATP酶和H~+-ATP酶活性及叶片中质膜和液泡膜Ca~(2+)-ATP酶活性先升高后下降，叶片中质膜和液泡膜H~+-ATP酶活性无显著变化，说明适当增加营养液中Ca~(2+)浓度后，可提高ATP酶的活性减轻低温伤害。

The results are as follows: the dwarf mutant A846 pertain to half-dwarf type, which height is about 38.64 cm on average, preponderating over the half-height of the wild-type, the elongation stage of the mutant represent dwarf character, internode elongation patterns of caulis are similarly the sh-type dwarf mutant, in which the first internode shows specific reduction, the elongation of these cells in the elongation zone immediately above the IM was dissimilar to the wild-type, longitudinal length of parenchyma cells were curtate, also the first internode exhibit markedly, which average is under the corresponding internode of the wild-type, the differentiation of the IM of each internodes of stem was similar to wild-type, as well as the number of internodes and the length of sheath of flag leaf.

结果表明：突变体A846平均株高38.64cm，大于野生型株高的一半，为半矮秆类型；其矮生性在拔节期显著表现；主茎茎秆各节间收缩比例不一，穗下第一节间显著缩短，与sh-型突变体类似；茎秆各节间居间分生组织细胞分化正常，由居间分生组织分化的细胞延伸受到不同程度的阻碍；各节间基本组织细胞纵向长度相应缩短，穗下第一节间缩短比例最大，其平均值小于野生型的一半；主茎节间数目与旗叶的叶鞘长类似于野生型。
