Effect of plant growth hormones on growth, tuber character and forskolin content of patherchur (Coleus forskohlii (Willd) Briq).

Abstract

This study was conducted at A field experiment was carried out in the research farm of RAK College of Agriculture, Sehore (Madhya Pradesh) during Kharif 2015-16). A field experiment consisting of Plant Growth Hormones MH (100 and 150 ppm), Cycocel (500 and 1000 ppm), NAA (50 and 100 ppm), GA3 (150 and 200 ppm) and and water spray as control to study the impact of plant growth Hormones on plant height, No. of branches, Number of tuber/plant, Lengh of tubers (cm) Diameter of tuber (cm). Fresh weight of tuber (g/plant) Dry weight of tuber (g/plant) and Forskolin Content (%)of Coleus forskohlii (Willd) Briq. 1000 ppm concentration of cycocel determined a decrease of the plant hight, incraes number of branches, number of tuber/plant, lengh of tubers (cm), Diameter of tuber (cm), fresh and dry weight of tuber (g/plant) and Forskolin Content (%)
