The Effects Of Cluster Effect On Individual Growth And Development In The Wild Chinese Chive

Cluster of growths is a kind of widespread exist to distribute a way in plants .Generally speaking, this kind of distribution can increase the teaching powder rate of the cross-pollination and the plant that have the lowest density can acquire reasonable growth density, meanwhile reduce competition, in total, cluster of growths is advantageous to those plants grows in clusters.However, it is still lack of research report in this area until now.The wild Chinese chive is a kind of Liliaceae Allium plant that can be collected easily in the SongNen meadow in the way of cluster of growths,it has highly potential value in economy and ecosystem.Wether the cluster of growths style of the wild Chinese chive is advantageous to the growth of individual and colony,or the influence of dissimilarity of the colony density for the growth of individual plant are still under further research.For this, this literary adopts the artificial methods of controlling the number of stubs in each colony, which is 1 stub(B set), 3-4 stubs(C set), 5-7 stubs(D set) and 8-10 stubs(E set), to study the effects and changes when the wild Chinese chive under the sistuation in different colony densities, the leaves upper the ground and statistics of the sexual reproduction. It is expected to announce that growth regulation in the cluster of growths of the wild Chinese chive, in which could provide theories and practice for the production of the wild Chinese chive, as well as complement with abundant new contents of cluster of growths researches. Study result enunciation:From the research of dissimilarity in colony density of the wild Chinese chive to the influence research of individual growth get, along with increment from B set to D set, the single stub biomass also increases gradually, although the E set has a little drops, still far more at the B set of single stub density.In one-way ANOVA analysis result manifestation, the dissimilarity densities upon the wild Chinese chive has significant influences of single stub biomass (P<0.05).The influence from the dissimilarity of density to the single stub leaf presents the same trend with single variety of homology of the stub biomass, as each has 5-7 stubs in densities, the performance shows best.The research of the influence from dissimilarity density to the sexual reproduction shows that: following the density increment along with the each group, the indexes of the single stub flowers of the wild Chinese chive,number of seed and seed weight etc are all increased. The sex reproductive capacity index sign attain biggest when density is 5-7 stubs , later on although there is a certain reduction, it is still far higher than in single stub.From different index sign correlation analysis ,the dissimilarity of densitieses a single stub leaf long and the weight of the part upper ground , and single stub leaf long and seed weight, exist a direct ratio. But the stem heavy of single stub upper part with of seed weight, the relativity does not show obviously. The above-mentioned result expressed reasonable colony density can give the advantage of individual growth and with each 5-7 stubs per colony for the superior density.
