The results of the determinating the activity of the CA in vitro showed that the CA of the water—fed individuals were in activing statics after eclosion. Because of the apperence of the Vg in haemolymph and the deposition of the vitellin in oocytes in the unfed females, it was shown that the CA in such individuals were in activiting statics, too. Again because in the water—fed females which did not lack the feeding action the activity of the CA showed dropping tendency gradually still, it could be said that the activiting of the CA was possibly effected by the nutrition but it was never related to the adult feeding action. In another respect, the brain of the female adult had not significant effect on the activiting CA. The oocytes could depositing vitellin in individuals removed brain tissue on the day of eclosion, which showed that the activting of CA was not concerned with brain.
CA活性的体外测定说明饲水个体的CA同样具有活性,不取食个体血淋巴中Vg的存在以及卵母细胞中卵黄的沉积表明,在不取食的个体中CA同样具有活性,所以CA的活化与成虫期的取食动作无关,与成虫是否取食花蜜也无太多的联系,但是CA活性的维持可能受成虫期营养的影响,如果以卵母细胞发育和CA体积大小作为CA活性的指标,则饲水个体CA的活性在后期受到了影响,说明饲水不能替代取食蜂蜜来维持成虫期CA的活性;成虫期脑对CA的活化无明显作用,羽化当日摘除脑的个体,其卵母细胞仍然可以沉积卵黄,说明CA的活化与脑无关,而是受某种不确定的因子的影响;用抗JH物质—早熟素—Ⅱ以10ug/虫的剂量在颈部点滴处理雌虫,对Vg的发生和卵巢的发育具有一定的迟缓作用,其原因有待于进一步的研究。

Compared to no Ca spraying, Ca spraying on young fruit could significantly increase fruit weight, lower morbidity of bitter pit and improve fruit quality. For the treatment of Ca spraying, total Ca, H2O and 1moL/L NaCl soluble Ca content increased, while N/Ca ratio, activity of PEA, SOD and POD, and MDA content in fruits decreased, compared to no Ca spraying.
幼果期喷钙显著增加了单果重,降低了苦痘病发病率,改善了苹果品质,并可增加果实全钙、水提取态和1moL/L NaCl提取态钙组分,降低果实氮/钙比、PEA、SOD和POD活性及丙二醛含量。

The result using inhibitors of Ca〓 channels supported above observation. When Ca〓 channels in plasma membrane were blocked by LaCl〓, verapamil or nifedipine, and the Ca〓 channels in endomembranes opened naturally, extracellular CaM couldn't induce 〓 increase. When Ca〓 channels in endomembranes were blocked by ruthenium red and the Ca〓 channels in plasma membrane opened naturally, extracellular CaM induced Ca〓 increase in guard cells, but the extent of Ca〓 increase was lower than that of control.
使用质膜Ca〓通道抑制剂LaCl〓、异博定、尼群地平及细胞内Ca〓通道抑制剂钌红的结果支持这种推测:在质膜Ca〓通道被阻断、细胞内Ca〓通道仍正常开放的情况下,保卫细胞〓不能被CaM诱导增加;细胞内Ca〓通道被抑制、质膜Ca〓通道正常开放的条件下,细胞外CaM诱导保卫细胞内〓升高的幅度不能达到不使用Ca〓通道抑制剂的水平。
