[Effects of potassium fertilization period on photosynthetic characteristics and storage root starch accumulation of edible sweetpotato].

Abstract: In this study, same amount of potassium (240 kg . hm-2) was applied as basal dressing (treatment 1) and as 1/2 basal dressing + 1/2 top-dressing at day 75 after planting (treatment 2), aimed to investigate the effects of potassium fertilization period on the photosynthetic characteristics of edible sweetpotato and the starch accumulation in storage root. As compared with treatment 1, treatment 2 improved the leaf photosynthetic rate and sucrose-phosphate synthase activity and the storage root's adenosine diphosphate glucose pyrophosphortlase activity, enhanced the starch accumulation rate in storage root (with an average increment of 6.
