单位叶面积 meaning in English
unit leaf area
Examples
- Generally speaking , leaf nitrogen content per unit leaf area increased under high irradiance and was significantly higher than those under low irradiance
损伤处理可使植株叶单位叶面积n含量降低，而单位叶重n含量却比未受损植株高。 - The result showed : in different light environments anti different plants , transpiring water volume and absorbing heat quantity of leaf area was very different
结果表明：不同的光环境及植物在单位叶面积内的蒸腾释水量及吸热量有很大差别。 - The main results are shown as follows : 1 under nacl stress , the succulent degree of leaves was enhanced , which was showed by measurement of well - developed palisade tissues , water - storing parenchyma and thick epidermis layer made of big parenchyma cells
另外随着nacl浓度增加，单位叶面积上的表皮细胞个数减少，表皮细胞长度、宽度、高度变大，即表皮细胞变肥厚，对叶的肉质化也有很大作用。 - On the contrary , nitrogen concentration decreased with increasing light levels . defoliation led to lower leaf nitrogen content but higher nitrogen concentration contrasted with controlled plants . researches showed that leaf nitrogen content and leaf nitrogen concentration change with different light and defoliation treatment
研究发现，单位叶重和单位叶面积n含量呈现不同变化的原因是由于不同处理植株比叶重之间有显著差异的缘故，光照水平的降低和叶损失都会使植株的比叶重减小。
