Abstract
The assimilation of 14CO2 and the accumulation of 14C-assimilates during grain filling period of wheat treated with dry-hot-wind were determined. The results are showed as follows: 1. Under the influence of dry-hot-wind, the chlorophyll content was decreased and the capacity of 14CO2-assimilation was also reduced. Assays of carbonhydrate content indicated that destribution pattern of 14C-assimilatcs was changed, the alcohol soluble fraction was decreased while the petroleum ether soluble fraction was increased. The total 14C-assimilates accumulated in the grain was reduced to a low level. 2. The hydrolysis and export of 14C-assimilates stored in stem was enhanced and the soluble carbonhydrates in the grain transformed more repidly into insoluble from, hence the treated plants ripened earlier than the controls. 3. Injuries caused by dry-hot-wind during grain filling period did not recover even under favorable conditions subsequently.
