Crowding as an Agronomic Factor Determining the Development of Plants and the Productivity of Linseed (Linum usitatissimum L.)

ABSTRACT

Nine sowing densities of linseed were compared in a two-year experiment. Self-regulation of the density of a linseed stand resulted in a differentiated branching of the plants. The number of capsules on a linseed shoot, as well as seeds in the capsule, and the number of seeds from the shoot were highly varied from year to year, and there is even a stronger differentiation in the weight of 1000 seeds. Linear relationships were noted between the mass of seeds from the linseed plant and the number of capsules. The yield of linseed was affected by both factors. An increasing sowing rate reduced the seed yield from the shoot and the plant. At lower seeding rates, the lateral shoots contributed in the seeds yield of the plant to a higher degree compared to the main ones.

摘要

在两年的试验中，比较了9个亚麻籽播种密度.亚麻林分密度的自调节导致植物的分化分枝.亚麻苗上的荚果数和荚果中的种子数，以及来自枝条的种子数逐年变化很大，1000粒种子的重量甚至有较强的分化.亚麻籽种子质量与荚果数呈线性关系.亚麻籽产量受两个因素的影响.播种速度的增加降低了地上部和植株的种子产量.在较低的播种速率下，侧枝对种子产量的贡献程度高于主枝.
