With seedlings of three maple A.oliverianum, A.sinense and A.longipes collected from Hengyang, hunan province as the experimental materials, the characters of physiology and biochemistry were determined in different drought condition through unwatered potted plant and compared with normal watering.

以采自湖南衡阳的3个槭属树种五裂槭(A.oliverianum)、中华槭、长柄槭的幼苗为材料，通过盆栽干旱胁迫，以正常浇水处理为对照，对不同干旱胁迫下的部分生理生化指标进行了测定。

QP of high and middle phosphor treatment was significantly higher than the control under the moderate and severe drought conditions, but there was no significant difference under wettish condition.

在中度干旱和严重干旱条件下，高磷和中磷处理的小麦叶片光化学猝灭系数显著高于对照，而在丰水条件下，3种处理基本相等。

Extracted DNA by CTAB, in proportion to the additions of PVP and β-mercap toethanol to the extraction buffer were capable of preventing browning from taking place in the extraction, Tris-Phenol (Stabilized with 0.1M Tris, pH 8.0)/Chloroform/isoamyl alcohol were used to remove protein and impurity in the second extraction, during crude DNA used to Isopropanol DNA and deterged by DNA detergent, without using RNase remove RNA, we detected the quality and concentration of DNA respectively for normal leaves and drought stress leaves by Agarose gel electrophoresis of genomic DNA and ultraviolet spectrometry photo.
