Effects of Vegetative growth on Reproduction growth of R.chinensis
Abstract：R. chinensis is traditional Chinese flowers, its rich colors, yellow and white , purple pink , colorful , widely used in horticulture and cut flowers, has an extremely important role in the world flower industry. In order to improve R. chinensis ornamental value, this experiment select shrub R. chinensis planted in the campus conduct phenological observations, research Effects of Vegetative growth on Reproduction growth of R.chinensis, Observing mother branch diameter 、 length, flowering branch diameter 、length, the number of leaves , the area of blade, the number of buds , flower size, the results showed that: (1 ) R.chinensis into the reproductive stage , vegetative organs stop growing, the number of buds remains unchanged in budding stage, the number of flowers bud is different between flowering branch , the number of flowering increase by changing over time, no difference in flower size ; ( 2 ) Making correlation analysis by phenological data and found that effects of flowering branch diameter on flowering branch length ，effects of flowering branch diameter 、length on the number of buds is extremely significant positive correlation , effects of mother branch diameter on flowering branch length ，effects of leaf area on number of buds is significant positive correlation , and the rest (effects of mother branch diameter on flowering branch diameter、number of buds ；effects of mother branch length on flowering branch diameter 、length、number of buds ；effects of number of leaves on number of buds ) no significant effect . Therefore , it is recommended to strengthen basal and heavy pruning in the early growing season of R.chinensis , to ensure there is enough mineral nutrients to absorb to promote germination and the growth intensity of flowering branch , increasing the number of buds and improve the quality of flowering .
Key words：R. chinensis; Prognosticate; Vegetative growth; Reproductive growth
