Therefore,it is necessary to determine the effects of removal of fruiting branches on plant growth and development,lint yield,and fiber quality in various types of Bt transgenic cotton.

Effects of nitrogen application rate on spatiotemporal variability of biomass accumulation of cotton s fruiting branch at flower and boll stage.;

By random arrangement and periodical observation the results showed that compared with no taking-off-leaves-branches cotton plant,the cotton plant of taking-off-leaves branches had higher shedding rate of buds and bolls in different leave position,and had longer shedding day.

We make use of adaptive binary image,morphologic thinning,remove pseudo-structures,distance-taxis of the extended point and high-power curvefitting to have slaved this problem.
