Abstract:

In this study, the effects of different factors on sessile tuberization of single-node stem of Dongnong 303 potato seedlings under different cultivation conditions, including changing chlorophyll, nitrogen, phosphorus, and potassium contents, are determined. The results showed that the sessile tuberization of single-node stem with a leaf was the best under the irrigation condition with a major element of MS in 1.0 culture liquid. The weight of sessile tuber that formed from the upper part with single-node stem of the plant transplanted for 40d was 0.79g. Sessile tuber could form if a single-node stem segment from the lower part was cut for 5d. The weight of the sessile tuber formed from the upper part of the plant that the terminal bud had been removed for 6d was 0.93g. During the formation of the sessile tuber, the contents of chlorophyll a and chlorophyll b exhibited a declining trend. The decline was greater at 3-5d and 4-5d, respectively, after cutting. However, the ratio of chlorophyll a to chlorophyll b was more stable. The potassium content of the leaves from the seedling cutting was the highest, whereas the phosphorus content was the lowest. The changes in nitrogen, phosphorus, and potassium contents exhibited a declining trend during the formation of sessile tuber.

Key words: Potato sessile tuber, Single-node stem, Chlorophyll, NPK content
