Effect of Density on Accumulation and Transformation of Photosynthesis Product of Different Type Forage Corn

doi:10.3321/j.issn:1000-7091.2006.03.012

Abstract

Abstract: Using the two varieties with the different type forage corn,their photosynthesis products and transformations under the different density were studied.The results showed the silage corn Keduo 8 laid particular stress on vegetable growth,it had larger LAI and higher biomass,there were bigger changed range between LAI and biomass;the dual purpose corn Shandan 310 laid particular stress on reproductive growth,it had smaller LAI and lower biomass,there were a littler effect of density on LAI and biomass.The density had regulation ability to the distribute ratio and transformation traits of photosynthesis product organs of two different types forage corn.The higher transformation ratios of photosynthesis product organs about Keduo 8 and Shandan 310 were respectively leaf and stem.

Key words: Forage corn, Density, Photosynthesis product, Accumulation, Transformation
