Abstract

Growth retardants are the chemicals that slows cell division and cell elongation of shoot tissue and regulate plant height physiologically without formative effects. Maleic Hydrazide (MH) is a plant growth retardant that reduces growth through preventing cell division but not cell enlargement. It is applied to foliage of potato to prevent sprouting during storage. In this study, Potato tubers were treated with MH at different concentration. The different developmental parameters such as sprouting, seedling length, no. of leaves, chlorophyll content and Sugar content were observed after some days. The result showed that number of sprouts were less in MH treated tubers than the controlled one. Seedling length reduced in MH treated tubers but the number of leaves were more in MH treated tubers. Again Chlorophyll content increased with the increasing concentration of MH. The sugar content was low in MH treated tubers. Thus the application of MH can induce the development by increasing leaves numbers and more chlorophyll content and yield of potato also increases

Conclusion

From the experiment, it is suggested that Maleic Hydrazide affects the growth germination of Potato tuber. Though the rate of germination is slower in MH treated tubers and the seedling length is less, the MH treated seedlings bear more leaves with high chlorophyll content as compared to controlled tubers. So, the leaves of MH treated seedlings are photosynthetically more efficient, which favours growth of the tubers and ultimately the production increases. Therefore, the application of growth retardant MH is advantageous and can be used by the cultivator of Potato tuber to increase yields
