Preliminary study of reproductive allocation in Cistanche deserticola / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>Discuss the trade-off between vegetative growth and reproductive growth.</p><p><b>METHOD</b>Vegetative modules and reproductive modules by large sampling were separated and quantitative charecters of organs and pattern of reproductive allocation were analysed of reproductive allocation were analysed.</p><p><b>RESULT</b>The phenotype plasticity of quantitative charecters were significant. Reproductive biomass was increasing at different stages. The mass of reproductive investment increased significantly with increasing individual size, the opposite of reproductive allocation. There were all significant positive correlations between the seeds weight and height, total biomass, vegetative biomass, reproductive biomass, fruit numbers, fruit weight.</p><p><b>CONCLUSION</b>The significance of phenotype plasticity is the cause of multiple elements. In the process of transferring from vegetative growth to reproductive growth, there was a trade-off between organs. Under individual growth and reproductive strategy, the variation of biomass was allocated coordinately.</p>
