The chromosome genomes of Deqin wild alfalfa variety (Medicago sativa L.), scattered alfalfa variety (AC-3) in Yunnan province and 8 foreign introduced cultivated alfalfas were classified and compared by karyotypic analysis.

以云南野生种紫花苜蓿、逸散种紫花苜蓿(AC-3)和8个国外引进栽培种紫花苜蓿为材料，采用核型分析方法对供试材料的染色体组进行了分类和比较。

Quenching of chlorophyll fluorescence decreased and Non-photochemical Quenching of chlorophyll fluorescence increased for both alfalfas under drought stress. Generally speaking, qP decreased less and qN increased more in the high drought-resistance alfalfa than in the low drought-resistance alfalfa, suggesting that when under drought stress, the electron transport activity and photosynthetic apparatus was damaged less in the alfalfa with high drought-resistance than in the alfalfa with low drought- resistance.

PSⅡ光化学淬灭系数、非光化学淬灭系数的变化表现为干旱胁迫下两种紫花苜蓿qP值降低、qN值升高，总体上抗旱性强的紫花苜蓿qP降低的幅度低且qN升高幅度大，表明抗旱性强的紫花苜蓿PSⅡ反应中心电子传递活性受到的影响小，光合机构的损伤程度低。

Using the observed data of spring-sowed two years fresh alfalfa growth condition and parallel climatic conditions,analysis is made of the alfalfa's growth height and the speed variation rule with time in the loess plateau area of East Gansu,and the correlation dependence of dry matter and the fresh grass with the activity accumulated temperature.
