| 摘 要： | 本文就长季节岩棉栽培中番茄叶片的生长特性进行了细致的观察及深入的研究， 认为番茄第一果穗下的基生叶， 光合养分主要用于自身建设， 随叶位提高叶片面积增大， 二者呈显著正相关（Ｒ２ ＝ ０－９９） 。两果穗之间的三片叶中以果穗上的第一叶叶面积较小， 这主要表现在叶宽的差异上， 而叶长相差不大， 这是由于养分竞争影响了叶宽的扩展而造成的。果穗之间充分成熟的叶片， 叶形比小于１ ， 即叶长小于叶宽。而未充分成熟的叶片， 叶面积随叶位上升而减小， 并且叶形指数在增大， 表明叶长生长先于叶宽。在植株的整个生长期间， 最大的叶片通常出现在１ ～５ 穗果之间（ 第１０ ～２５ 片叶之间） ， 这与前期座果少、冠层未封闭、见光好有关。叶片的这些生长特性受营养液组成（ＥＣ＝ １０ｄｓ／ｍ） 及蒸腾势处理的影响较小

| Abstract: | The paper studied about the leaf characteristics of tomato grown in rockwool during long season growing The leaf area of the leaves bellow to the first fruit truss was increased with the increasing of leaf number Assimilation was mainly used for leaf itself Among the three leaves between two fruit trusses, the first leaf above fruit truss was smaller then the leaves next to it The difference mainly came from the leaf width because of the competition of assimilate The leaf length had not so much difference Ratio of leaf length/width (L/W) was smaller than 1 in the full-growing leaves between fruit trusses, and it meant that leaf length was smaller than leaf width However, the leaf area of leaves that was not full-growing and near to the growing point was decreased with the increasing of leaf number, and the ratio of L/W was increased This result showed that after the full expansion of leaf length, leaf width was expanded In the whole growing period, the biggest leaf area in a plant was normally present in between the fruit trusses 1-5 or the leaves 10-25 This might come from the fewer fruit trusses, and canopy was not closed in earlier stage and there was enough radiation The characteristics of leaf growing was not affected by the nutrient composition (EC=10) and transpiration in the experiment |
