通过蓖麻生长发育过程中光合产物的积累、分配规律研究，发现蓖麻各器官干物质积累呈现慢-快-慢的变化趋势，其干物质积累过程可用Logistic函数和一元二次函数描述；蓖麻生育期内各器官干物质积累的速率变化规律为：生育初期缓慢，在中期迅速加快，后期逐渐下降；蓖麻生育初期干物质主要分配于营养体，随着生育期的推延，营养体干物质分配率逐渐下降，而籽粒初始干物质分配率生育初期低，之后逐渐提高趋势．

The study of castor's photosynthesis product accumulation and law of distribution in the process of growth and development found that the dry matter of castor's different organs accumulation appears slow - fast - slow ,the process of dry matter accumulation can be described by logistic function and a quadratic function; the law of rate variation for dry matter accumulation of each organ during the castor's growth as follows: the initial slow fertility, the rapid acceleration in the medium, later gradually declined; The castor's dry matter mainly allocated to vegetative in the beginning of birth, with the delay of birth period, distribution rate for vegetative dry matter gradually decreased ,and distribution rate for the grain's initial dry matter was low in the beginning of birth, then increased trend gradually.
