The results showed that the 50% leaf removal could increase the yield of sound boll by 24.4% that suggested the happening of overcompensation. The 25% leaf removal had no influence on cotton plant height and protein content in leaves, suggesting the 25% leaf removal in standard falling into the category of growth redundancy, but the climax in protein content in cotton leaves postponed about one week.

在棉花盛蕾期，用剪刀剪除棉花标准叶面积的25%和50%，模拟田间害虫的食叶危害程度，结果显示：50%去叶处理可使棉花成铃数增加24.4%，产生超补偿现象。25%去叶处理在短时间内对棉花的株高和叶中蛋白质含量都没有影响，植株株型亦无大的变化，表明25%叶面积属于生长冗余范畴。

The research of cytology shows that there are dramatically morphological and structure changes in the leaf: the cells of mesophyll array loosely and parenchyma cells reduced, cambium becomes thinner and degree of xylem becomes more serious, the content of chlorophyll dropped; the changes of conducting tissue and stoma structure affect transport and allocation of water and nutrient, hinder leaf growth and disturb regular metabolism of leaf, at last lead to wilt, rot and become crisp papyraceous.

细胞学研究表明，病叶组织的叶肉细胞排列疏松，薄壁细胞层次减少，形成层变薄，木质化程度加深，叶绿体减少；在病叶中由于疏导组织和气孔的结构发生变化，影响养分和水分在植株体内的运输和分配，干扰叶片的正常代谢，抑制叶片的生长发育，最终导致叶片失水萎缩、干枯，变为焦脆的干纸状。

According to the partial correlation coefficient between the growth of forest and leaf nutrient,the N、 K content in leaf of clone S2 affected the growth of breast-height diameter mostly,and influenced the growth of tree height were Mn 、 P 、 N、 Cu content.The K、 N、 P content in leaf of clone S8 affected the growth of breast-height diameter mostly,and influenced the growth of tree height were Ca、 N content.

4从林木生长与叶片营养的偏相关系数大小来看，影响无性系S2人工林胸径生长的主要是叶片中N、K元素含量，而影响树高生长的主要是叶片中Mn、P、N、Cu元素含量；在无性系S8人工林中，影响胸径生长的主要是叶片中K、N、P元素含量，影响树高生长的主要是叶片中Ca、N元素含量。

Eight common domestically and foreign cultivated Cucurbita pepo L. cultivars were selected to study 14 morphological indexes influencing plant type under sunlight greenhouse. And effects of plant type on yield formation was discussed. Results show that the main morphological indexes influencing plant type are plant height, internode length, average leaf area, functional leaf quantity and leaf angle.

选取近年来国内外广泛栽培的8个西葫芦品种为试材，在日光温室中对影响西葫芦株型的14个形态指标进行研究，分析了影响西葫芦株型的主要形态指标，探讨了西葫芦株型对产量形成的影响。
