Architecture Branching and Biomass Allocation of Leonurus spp.,an Annual grass Planted in the Epidemic Area of Schistosomiasis Prevention
摘要
Abstract
In this paper,studies were made of the growth and fruit feature of Leonurus spp.,a snail control species planted in the Snail Control Afforestation pilot area of Renshou County.Leonurus spp.had two types of architecture：acrotony and basitony,the former adapted to the fertile habitat and the latter to the poor.There were greater height（1.6 vs 0.95）,more branches（the first branch：8.5 vs 6.6;the second：32.6 vs 9.7;the third：0.7 vs 0）,taller bifurcation ratio（4.7 vs 2.3） of Leonurus individuals in the ridges between fields than in the poor intercrop stand.In the two habitats,individual height was not related to branches of the first class and had a significant relation to the amount of the second class branches with a paullic curve.The branch diameter,inter-node length,and fruiting amount in different position or nodes all showed an obvious relation of paullic curve,indicating a significant position effect and with a develop pattern of baisitony in Leonurus spp.planted in this site.After analyzis,it was found that the architecture parameters of reproductive branches as diameter near node and inter-node length both had an obvious linear relationship with the fruit amount of this node,implying that this position effect was brought about by the architecture size,and attributed to the architecture limitation.With the individual growth,the calculated ratio for biomass of branch stem,root,fruits and leaves took a decreasing order,implying that the accomplishment of the cultivation aim could require the optimal architecture feature.On the whole,the growth of Leonurus individuals adapted to the heterogeneous habitat through the bifurcation ratio,and its modular reproduction had a dependency of architecture.关键词
