With quadratic regression general rotation design,effects of CaCl2,SA,Hydrogel on drought resistance of Davidia involucrate was studied by pot culture experiment.

采用二次通用旋转组合设计，对珙桐幼苗进行盆栽控水试验，研究了水分胁迫下CaCl2、SA和保水剂对珙桐幼苗抗旱性的影响。

Davidia involucrate, a relic species of paleotropical kingdom in Tertiary period and belonging to Davidiaceae with a single genus, is one of the first-class protective plants in China. In this paper, a pot culture experiment with quadratic general rotation design was conducted to study the effects of CaCl2, salicylic acid, and a water-retention agent on the drought resistance of D.

采用二次回归通用旋转组合设计，对国家一级保护珍惜植物珙桐幼苗进行盆栽控水试验，研究了水分胁迫下氯化钙(CaCl2)、水杨酸和保水剂对珙桐幼苗抗旱性的影响。

Jatropha is drought resistant, which eliminates risk, it is a non-edible plant, easy to establish, grows relatively fast (20cm in the first month and up to 2,5 m in the first year).

麻疯树是抗旱，从而避免了风险，它是一个非食用植物，容易确立，增长较快( 20cm的，在头一个月高达2，5米的第一年)。

The indexes of Lathyrus sativus,Vicia vracca and V.amoena with big seeds de...

小粒种子的抗旱性明显好于大粒种子。

The results showed that the varieties Longjing2 and Longjing3 were adaptable to dry direct seeding, and their yields could reach 5 872 kg/hm~2 and 5 783 kg/hm~2 respectively, which could be used as draught- and water conservation seeds planted in spring in northest.

对引进的水稻品种进行旱直播种植，筛选结果表明，龙粳2号和龙粳3号适宜旱直播种植，产量可达5 872和5 783 kg/hm2，可作为东北稻区春季抗旱节水栽培的旱直播水稻用种。

Increase in SOD and POD activities in Paeonia suffruficosa leaves enhanced the resistance to drought stress.

干旱胁迫下，牡丹叶片SOD和POD活性增强，在一定程度上提高了植株的抗旱能力。

With different concentrations of polyethylene glycol (PEG6000), the treatment of water stress was simulated: With the decrease of water porential, the germination percentage, speed and index decreased in total and increased at the temperate water stress (-0.2MPa), indicating that A. pedunculata Pall. has drought tolerance in certain extent.

用不同浓度的PEG6000模拟土壤干旱对种子萌发进行人工水分胁迫处理，随着水势下降，种子发芽率、发芽速度、发芽指数及发芽活力呈下降趋势，在轻度水分胁迫下(-0.2MPa)发芽率有所上升，表明长柄扁桃具有一定的抗旱性。
