leaf area ratio

In a colonizing population of Datura stramonium, there was significant plasticity in specific leaf area, leaf area ratio and number of leaves; traits that are associated with light capture in response to high density.

在曼陀罗（Datura stramonium）的移植种群中，比叶面积、叶面积比和叶片数都具有显著的可塑性，这些特征都与捕光能力对高密度的响应有关。

The grain yield increased with increasing total dry matter accumulation, and significantly positively correlated with dry matter accumulation after heading, total spikelet number, LAI, and spikelet/ leaf area ratio.

稻谷产量随干物质积累总量的增加而提高，与齐穗后干物质积累量、总颖花量和LAI呈极显著正相关，与粒叶比呈显著正相关。
