Seven grapevine cultivars originated from different regions, i. e.'Carbernet Sauvignon' and'Queen of Vineyard'(two members of the Western Europe Cultivars Group),'Rizamat'(a member of the East Cultivars Group),'Red Double Taste'(a hybridized cultivar from Vitis vinifera L. and V. labrusca L.),'1103Paulsen','Red Globe'and 'Autumn Royal'(two new hybridized cultivars between cultivars groups which were warmly planted in recent years) were selected. After different drought stress, a combined measurement of gas exchange and chlorophyll fluorescence was conducted to evaluate the effects of drought stress to photoinhibition, as well as the role of photorespiration and xanthophyll cycle in photoprotective mechanism. After photorespiration and xanthophyll cycle were separately inhibited, the complementary effect of these two photoprotective pathways was discussed. Detached leaves of different grapevine cultivars, i. e.'Cabernet Sauvignon','Cabernet Franc','Merlot', and a rootstock,'1103Paulsen'were selected as materials, and photoinhibition degree, photorespiration activity as well as its photoprotective function under drought stress were studied. The results are as follows: 1. Under the same drought stress treatment, different photoinhibition degrees formed in different grapevine cultivars.

We may well explain why ricin-induced apoptosis showed no typical DNA ladder. The presence of laddering in DNA gels implies an apoptosis process, but its absence does not rule out the apoptosis. The ricin 0.05μmol〓 had no effect on the 〓 phase of cell cycle, but induced 〓 arrest. The ricin may affect the balance of synthesis and destruction of proteins that controlling the cell cycle.

检测到DNA梯度表明细胞发生了细胞凋亡，未检测到DNA梯度不能否认凋亡的存在。0.05μmol.L〓的蓖麻毒素对HeLa细胞周期的G〓/G〓期无影响，而诱导了G〓/M期阻滞，蓖麻毒素可能引起一些控制细胞周期蛋白的合成与降解发生紊乱。
