Abstract
The present experiment entitled “To study the effect of different concentrations of plant growth regulators on rooting of litchi (Litchi chinensis Sonn.)) Air layers” was conducted at Punjab Agricultural University, Regional Research Station, and Gurdaspur during the year 2015-16 and 2016-17. The experiment was laid out in Randomized Block Design with thirteen treatments of different concentrations of plant growth regulators each of IBA and NAA i.e.1000ppm, 2000 ppm, 3000 ppm, 4000ppm, 5000ppm and 6000 ppm and replicated thrice with a unit of one plant in each replication of a treatment. The result showed that among different application of IBA (Indole-3-butyric acid), the 5000 ppm IBA treated layers took lesser days to root initiation (16days) and also gave better results with respect to all the parameters studied including per cent rooting (90.45%), number of roots (35.52), root length (12.5cm), percent survival (95.25), days to come leaf after detachment (12days), root thickness (1.62mm), fresh weight of root (3.35gm), dry weight of root(2.15gm),fresh weight of shoot (52.25gm), dry weight of shoot (32.25gm) and root: shoot ratio on dry weight basis (0.067) as compared to other treatments along with control. Similarly, among different treatments of NAA(1-Naphthaleneacetic acid), the 5000ppm NAA treated layers took lesser days to root initiation (20 days) and also gave better results with respect to all the parameters studied including per cent rooting (80.5), number of roots (30.25), root length (10cm), percent survival (84.2), days to come leaf after detachment (14), root thickness (1.42mm), fresh weight of root (2.75gm), dry weight of root (1.50gm), fresh weight of shoot (47.65gm), dry weight of shoot (27.42gm) and root: shoot ratio on dry weight basis (0.04) as compared to other treatments along with control.
