Upward curling of the leaf blade (called rolled leaf) can result in enhanced erect-leaf habit, increase erect duration and promote an overall erect leafcanopy.
叶片向上卷曲(称为卷叶)可以引起直立叶的表型,延长叶片直立时间,促进形成直立叶株冠。

Canopy is measured according to leaf-area-index (LAI) relative to wall area; for each unit of LAI, sunlight decreases by about half.
雨棚是根据相对于墙体面积的叶面积指数(LAI)来测量的;每单位LAI,日照减少约一半。

The Leaf Angle Distribution (LAD) and Leaf Area Index (LAI) are important descriptors of the vegetation canopy.
