| Abstract: |
| Four typical dual-purpose type of oil-cilia varieties (strains) and a cilia-use variety (strain) of flax were selected as test materials. From the early flowering season, the blossoming flowers each day were
marked, with every five-day as a period, and the marking was done in three periods, while all the other flowers were regarded as the fourth period. The seeds were picked five days after blossoming and measured to find out dry matter accumulation of seeds in different periods and parts. The result of logistic growth curve equation analysis showed that seeds in middle fruit of cilia type flax were relatively heavy, each had more fruit seeds, and the bottom took the second place, while the top was the lightest; However, the fruit seeds of the dual purpose type flax were heavier, and the maturing rate reduced from bottom to top in proper order. As for a single plant, the output of the middle seeds took the larg
est proportion. The seeds dry matter accumulation and the average accumulation rate, the max accumulation rate, fast developing period accumulation rate were in positive correlation. Among all of the varieties (series), the developing rate of the fast developing period was notablly overtop the increasing and the slowly increasing period, the weight increment was different among different parts of seeds, the bottom seeds of the dual purpose type flax had lower developing rate, long continuous time, more dry matter accumulation, while the top seeds had high developing rate, but had short continuous time, and light seeds. However, the cilia-using type had the same trend, but had little difference among various parts. |
