葡萄叶片和其它植物叶片一样是光合作用、呼吸作用和蒸腾作用的主要器官。生产上一股用叶片的大小、薄厚,颜色来衡量树体的营养状况和群体结构是否合理。因此,葡萄叶面积的测定对研究它的生物学特性及提高产量和品质有重要意义。
Grape leaves, like other plant leaves, are the main organs of photosynthesis, respiration and transpiration. The production of a share of the leaf size, thickness, color to measure the nutritional status of the tree and the community structure is reasonable. Therefore, the measurement of grape leaf area is of great significance for studying its biological characteristics and improving yield and quality.
