When EGTA (Ca〓 chelator), Verapmil and LaCl〓(Ca〓 channel blockers) were used to treat tomato fruit at green mature and strawberry fruit at white stage with ethylene, they could reverse ethylene-induced increase in ethylene production in tomato and strawberry, PG activity, lycopene content, soluble protein content in cell wall in tomato and degradation in soluble protein in strawberry, which indicated blocking Ca〓 channel in plasma membrane or chelating Ca〓 can decrease intracellular Ca〓, further inhibite ethylene-induced maturation, ripening and senescence of fruit.

用质膜钙通道阻断剂异博定、钙通道Ca〓竞争性抑制剂以及Ca〓专一性螯合剂与乙烯一起处理绿熟期番茄果实和乳白期草莓果实，均可抑制乙烯诱导番茄和草莓的乙烯生成、番茄PG活性的提高、番茄红素含量的增加和细胞壁可溶性蛋白含量的增加以及草莓可溶性蛋白的分解，表明阻断质膜Ca〓通道或螯合胞外Ca〓以减少胞内Ca〓能抑制乙烯对果实的催熟作用，间接证明乙烯对果实成熟衰老的诱导与胞外Ca〓内流引起的胞质Ca〓浓度的增加密切相关，表明乙烯信号转导可能与钙信使有关，调节胞质Ca〓浓度可调节乙烯对果实的催熟作用。

The interrelation of PG activity with softness, storability and susceptivity to stimulus from exo-ethylene was discussed.

讨论了PG活性与果实成熟、耐贮性及软化的关系，及对外源乙烯刺激的敏感性。

It was concluded that PG not only played an important role in trimer formation but also effected the pigments binding and the energy transfer within the LHCⅡ.

以上实验结果证明，PG及其反式十六碳一烯酸不仅在LHCⅡ三聚体的形成中具重要作用，而且还影响色素分子在LHCⅡ三聚体中的结合状态以及叶绿素b到叶绿素a的正常能量传递。

The histiocytes were positive both for kp1 and PG-M1, suggesting that these cells were infiltrating cells from peripheral blood rather than histiocytic differentiation of tumor cells.

组织细胞PG-M1 和kp1标记均阳性，可能是炎症或免疫反应的产物。

The results indicated that heat treatment significantly delayed the increase of fruits firmness and the decrease of extractable juice rate, inhibited the increase of PAL, POD and PPO activities and the decrease of PG activity. Meanwhile, heat treatment reduced the accumulation of lignin and protopectin and maintained higher content of water soluble pectin, thereby prevented the development of flesh leatheriness and maintained the quality of cold-stored loquat fruits.

结果表明，热处理可以有效控制果实硬度的上升和出汁率的下降，抑制PAL、POD和PPO活性的上升及PG活性的下降，减少原果胶和木质素的积累，保持较高的水溶性果胶含量，从而减轻冷藏枇杷果实的木质化症状，保持较好的食用品质。
