Research on tripping phenomenon and propagation characteristics of wild Trifolium in Xinjiang

To understand tripping phenomenon and reproductive characteristics of Xinjiang Trifolium, flowering habit, pollen spreading time and the influence of different mating pattern on reproductive characteristic were studied. The results as followed: 1) flower from budding to wilting maintained 50~52 h, pollen display belongs to keel valvular insufficiency; 2) the pistil stigma crazed when wing petal grow to 1/2 of flag petal; 3) the podding rate of Trifolium from Changji desert steppe in the autonomous selfing was highest (98.61%); the podding rate of Trifolium from Urumqi Nanshan mountain meadow under homologous strain cross-pollination was the highest (100%) ; the podding rate of Hutubi Trifolium under forest belt with free pollination was the lowest (96.30%). The results of this study can provide some references for further study on breeding system and reproductive biology of Trifolium repens.
