【摘要】 应用长宽系数法测定苎麻叶面积时,需要求出相应的换算系数。根据本试验结果说明,在上海地区,芦竹青品种,利用种子繁殖的,其叶面积的换算系数应为0.65,利用种根繁殖的,其叶面积的换算系数应为0.66。如用比重法测定叶面积时,其换算系数均为0.95。更多还原

【Abstract】 Leaf area measure, as a physiology index, is important for shoot diagnose in field, so the suitable conversion coefficient should be determined for the leaf area measure. In this test Lu Zhu Qing, a variety of ramie, is used as material, which is bred by both seeds and subterraneous stem. The result showed that in Shanghai area the coefficient the former′s is 0.65 and the later′s is 0.66 for L×W methods, and it is both 0.95 for specific gravity method.更多还原
