The percentage of total biomass allocated to roots was positively correlated with WUE for the seven investigated species (r=0.93, p.01). Results indicate that the species investigated are typical C3 plants. These spring ephemerals are characterized by higher P T and lower WUE in comparison with other desert species. The unique biomass allocation of low root/aboveground biomass ratio, higher leaf area ratio, higher leaf mass per unit leaf area, and photosynthetic traits are involved in the physiological mechanisms that contributed to the rapid growth of desert spring ephemerals.

项目简介：中单808由中国农业科学院作物育种栽培研究所选育，生育期126天左右，株高314cm左右，穗长21.8cm，2004年河北省农林科学院植物保护研究所抗病鉴定结果：抗小斑病，中抗弯孢菌叶斑病，茎腐病，高抗大斑病，瘤黑粉病，矮花叶病，感玉米螟。2005年西南生产试验中平均亩产571.29kg，比对照增产17.85%。

The result showed there existed significant differences among families in seedling growth, dry matter accumulation, leaf shape as well as root parameters at high and low nitrogen levels. Remarkable reduction in seedling height, dry matter accumulation, leaf and root parameters were observed under low nitrogen stress, whereas larger proportion of photosynthesis production was allocated into roots to promote nitrogen absorption. Family variation in seeding growth, leaf and root parameters were increased under low nitrogen stress in comparison with high nitrogen level, which would be benefit to discriminate superior L. chinense families with high nitrogen efficiency. Nitrogen efficiency of different L.

结果表明：不同氮素水平下，马褂木苗的生长、干物质积累、叶片和根系等性状皆存在显著的家系遗传差异；低氮胁迫将显著抑制马褂木苗叶片发育和根系生长，影响苗高生长和干物质积累，但低氮素水平下生产的光合产物则较多地分配至地下根系部分以促进对氮素的吸收利用；与高氮处理比较，低氮胁迫加大了苗木生长、叶片和根系参数等家系遗传分化，有利于鉴别高氮效率的马褂木优良家系。
