The results were as follows: The stomatal conductance of winter wheat flag leaves treated with 10–50 mg/L ALA were significantly higher than that of the control (0 mg/L ALA); however the promotive effects of 10–50 mg/L ALA on stomatal conductance at flowering and milky stage was stronger than at dough stage. Applying 10–50 mg/L ALA increased the net photosynthesisrate of winter wheat flag leaves.

结果表明，10～50 mg/L ALA处理的叶片气孔导度高于不喷施的对照，但在开花期和乳熟期对气孔导度的促进作用大于腊熟期；叶片净光合速率也明显高于对照。

Five minutes is the optimal irradiation time for ALA-PDT by Xe lamp under the same irradiation conditions. Irradiation injury caused by the light alone was slight, but the destruction rate of ALA-PDT was very high. Conclusion: Xe lamp's action spectrum is wider and it's power is higher, so it's better than 532 nm laser for ALA-PDT.

结果：532 nm连续激光和脉冲激光对K562细胞的ALA-PDT抑制率均较低，增加光剂量也不能有效提高ALA-PDT的抑制率；氙灯在功率密度为350 mW/平方公分、光照5 min时就能达到最佳的光剂量，此时单纯光照对K562细胞的光损伤作用很小且ALA-PDT效率很高。

The chelate structure was examined by AFM scaning, single strand structure at AFM gram is Ala-Gln, two combined single strand is Ala-Gln-Zn~(2+), and atomic radius of Ala-Gln-Zn~(2+)'s conjunctive atom is about 0.24 to 0.25nm, which is near to Zn~(2+), so the conjunction atom is Zn~(2+). Thus the coordination reaction and the molar ratio 2:1 is proved again.

原子力显微扫描指出，大量出现的单一弯曲链状结构是Ala-Gln分子，而两两组合连接的链状结构，则是Ala-Gln-Zn~(2+)螯合物，且连接两个链状结构、半径约为0.25nm的中心原子是Zn~(2+)，证明Ala-Gln与Zn~(2+)形成配位比为2：1稳定螯合物。

Results The strongest photoinactivation effect occured in the HEP-2 cells co-cultured with 1 mmol/L ALA for 8 h. The killing activity of ALA-PDT to the HEP-2 cells was positively correlated with the power density of the irradiation (r=0.88, P＜0.05).Conclusions ALA-PDT can effectively kill the cultured HEP-2 cells in vitro. The optimal killing activity was related to the time and the power density of the laser irradiation.

结果 (1)光照时机选择在ALA与HEP-2细胞培养8 h时杀伤效应最强；(2)ALA-PDT对HEP-2细胞的杀伤效应与照光能量呈正相关r=0.88，P 结论 ALA-PDT能有效地杀伤体外培养的肿瘤细胞，其杀伤最佳效果与照光时机和照光能量有关。

ALA had obviously toxic effect on O. chinensis. Moreover, ALA caused the photoinactivation of AChE and GPx, which induced nerve transmission blocking and the capabilities to defend oxidation damage declining. Meanwhile, high-dose ALA could activate GSTs, which caused a feedback inhibition of insect to the phototoxic substance.

ALA对雌、雄中华稻蝗均有明显的毒性效应；ALA可引起AChE和GPx光失活，从而导致中华稻蝗神经传导受阻同时抵御氧化损伤的能力下降；高剂量ALA激活GSTs，可引发昆虫对光毒性物质的自身反馈抵御反应。
