The results showed that the soil configuration was improved by controlled irrigation, with increasing of root density in deep soil and sugar content of berry. Meanwhile the acid and salt content of the berry decreased and pH was modified. The wines had better aroma and flavor under controlled irrigation. 3825-4800m 3·hm -2 water per year was needed in controlled irrigation, saving 36% water compar...

结果表明，节水灌溉显著改善了土壤结构，增加了深层土壤的根系密度；提高了果汁糖含量，降低了酸含量和全盐含量，改善了pH值；提高了葡萄酒的感官质量，酒体丰满，香气浓郁，滋味更好；年灌溉用水量 382 5～ 4 80 0m3 ·hm-2 ，比常规灌溉节水 36 %。

As support, Agarose can benot only used in normal condition, but also in denaturalization (for example, 6 mol/Lhydrochloric acid carbamidine or 8 mol/L urea). Herein, the preparation of IMACmatrixes were conducted using agarose as support, carboxymethylated aspartate as chelating ligand and Co~(2+) and Ni~(2+) as chelating center ions.

本实验用琼脂糖作为基质，选用四配位，与金属离子有较强作用力的羧甲基天冬氨酸为配基，以Co~(2+)、Ni~(2+)作为螯合金属离子，合成了一系列金属螯合亲和色谱填料，并对其蛋白质分离性能进行了研究。

The results show that during the development of the oriental tobacco leaves, the activity of acid invertase was decreased; the changes of GS reached its peak in the 20dans in Samsun, but in the 30dans in Basma and Canik ;the activity of PAL was decreased in the 30dans; The content of total nitrogen was decreased with the mature leaves, but nicotine、total carbon and soluble total sugar were increased. Different varieties, carbon and nitrogen metabolism key enzyme activity and the content of metabolites were different.

结果表明，在香料烟叶片发育过程中，酸性转化酶的活性均呈下降趋势；谷氨酰胺合成酶的活性Samsun品种在20d叶龄时最高，而Basma和Canik在30d叶龄时最高；苯丙氨酸解氨酶的活性均表现为30d时最低；随着叶片成熟总氮含量降低，烟碱含量升高，总碳、可溶性总糖随着叶片成熟其含量呈升高趋势；品种不同，碳氮代谢关键酶的活性及代谢产物的含量变化均有很大差异。

Mascagni were held into a solution containing calcium, ethylene glycol bis-amino tetmacetate and water, respectively. The effects of calcium were studied by measuring the ornamental quality of cut flowers and the physiological characteristics such as calmodulin, abscisic acid, gibberellins, zeatin, endogenous calcium, malondialdehyde and soluble sugar in florets.

以唐菖蒲红色品种'马加烈'切花为材料，瓶插在含有乙酸钙或钙离子专一性螯合剂乙二醇二乙醚二胺四乙酸的溶液中，分析乙酸钙对切花观赏品质的影响以及第1和第3朵小花内钙调素、脱落酸、赤霉素、玉米素、Ca(上标 2+)、丙二醛和可溶性糖含量的变化。
