佛罗兰娜花生的生长大致可分为两个阶段,即营养生长阶段,生殖生长阶段。每一阶段生长发育的速度和模式受生长环境的影响,对作物能够达到遗传产量潜力的程度将产生重大影响。 营养生长 佛罗兰娜品种是一种匍匐生长的蔓生型花生。植株的营养生长主要包括主茎和两个侧枝及其以后长出的一些分枝、茎和叶。在播后的头40天内,茎的伸长和叶片的发育较缓慢(见图), 在最适宜的环境条件下,营养生长在播后40-110天之间迅速增加,此期出现叶面积增长4至5倍的情况并非鲜见。大部分荚果也是在这一期间形成的,正如后
Florens peanut growth can be broadly divided into two stages, namely vegetative growth stage, reproductive growth stage. The rate and pattern of growth and development at each stage is influenced by the growth environment and will have a significant impact on the extent to which the crop can reach its genetic yield potential. Nutritional Growth The Florentine variety is a creeping peanut creeping growth. The vegetative growth of the plant mainly includes the main stem and two lateral branches and some later branches, stems and leaves. In the first 40 days after sowing, stem elongation and leaf development were slower (see figure). Under the most suitable environmental conditions, vegetative growth rapidly increased between 40 and 110 days after sowing, and the leaf area appeared during this period A 4 to 5-fold increase is not uncommon. Most pods are also formed during this period, just as later
