Abstract
In order to study the effect of Zinc(Zn) on the grain development and Zn accumulation,dry matter and Zn content in organs of detached wheat spikes in vitro culture were determined under two levels of Zn application(19.5 and 195 μg/mL,respectively).The experiment material was Jimai 20,which grew in the field 2 days after anthesis.The results showed that with the days of culture added,dry matter accumulation of detached spikes increased.Under high Zn treatment(195 μg/mL Zn),dry weight of internode next to peduncle,peduncle,flag leaf,flag leaf sheath,rachis and glumes were more than those under low Zn treatment(19.5 μg/mL Zn).However,dry matter accumulation in grains under high Zn treatment was only as one tenth as those under low Zn treatment.Therefore,low Zn treatment was more benefit to the dry matter accumulation of detached spikes.With the days of culture added,Zn concentration in organs tended to rise.Furthermore,Zn concentrations in organs under high Zn treatment were all significantly more than those under low Zn treatment.And there were significant differences in Zn concentration among organs.Zn concentration was greater in flag leaves,and less in grains.With the days of culture added,Zn accumulation of detached wheat spikes also increased.And the adding trend can be described as fast-slow-fast.There was a slow increase in the number of Zn accumulation of detached spikes form 15d to 20d after culture.Zn concentration in organs except grain under high Zn treatment tended to jump sharply compared with low Zn treatment.Under low Zn treatment,there was more Zn accumulation in glumes,grains and flag leaves,the proportion of Zn accumulation in grains was 20 percent.Moreover,there was more Zn accumulation in glumes and flag leaves under high Zn treatment.But under high Zn treatment,Zn accumulation in grains was the least,and it was only 3 percent of total Zn accumulation.
