为了研究植株结构与花卉生产的关系，研究了弯曲处理和种植密度对月季幼嫩植株基梢形成的影响。弯曲初生芽后，最基本的两个芽长出的概率较大。这两个芽在腋芽鳞片的腋部已经作为次生芽存在，当被用作繁殖时。当弯曲被推迟时，这种可能性更加明显。初生枝条的源量主要反映在叶面积指数(LAI)上，由弯曲期决定。延迟弯曲增加了单株基梢的发育速率、直径、重量和横截面积。在基梢形成的早期阶段，植株生长速率与叶面积指数(LAI)呈正相关，表现为每日干重增量，但植株生长速率在T0后28d达到最大值(T0)。
SummaryTo examine the relations between plant architecture and flower production, the effect of bending practices and plant densities on basal-shoot formation was studied in young rose plants. After bending the primary shoot, there was a greater probability for the outgrowth of the two most basal buds. These two buds are already present as secondary buds in the axils of the scales of the axillary bud when used as a cutting for propagation. This probability was even more apparent when bending was delayed. The source capacity of the primary shoot, mainly reflected in the leaf area index (LAI), was determined by date of bending. Delayed bending increased the development rate, diameter, weight and cross sectional area (CSA) of basal shoots per plant. Plant growth rate, expressed as dry-weight increment per day, was positively related with LAI (and thus light interception) during the early phase of basal-shoot formation, although a maximum in plant growth rate was reached when stems were bent 28 d after T0 (ti...
