Abstract
Effects of planting density o n activities of several enzymes in Weiyou 56,a fodd er hybrid rice combination ,and its relation to protein content and yield were studied by way of field experiment and biochemistry analysis.The resul ts showed that the decrease of density enhanced the activities of PEP carboxyl ase (PEP C),glutamine synthase (GS) in leaves and ADP glucose pyrophosphorylase (ADPGP ) and GS in grains, and increased the content of nonprotein N, protein N and to tal N in le aves and grains, which results in increase of the protein content in brown rice. T he rational density of 300 000 hills/hm~2 had the highest yield and higher prot ein content in brown rice, thus benefited the formation of both high yield and high protein content of fodder hybrid rice, which was associated with the highest a ctivities of SS i n grains and sucrose-phosphate synthase(SPS) in leaves and higher activities of PEPC and GS in leaves and grains under such planting density.
