ABSTRACT
Litchi (Litchi chinensis) is mostly propagated through air layering which is cumbersome because of low survival rate of layered plants, more requirement of mother stock and labor intensive method. To address these issues an alternative technique has been employed for quick multiplication of litchi. In the present study we have investigated the influence of various levels of Indole Butyric Acid (IBA) on four Litchi cultivars (Gola, Surahi, China and Bedana) for root induction, its development and success rate of survival in hardwood cuttings. Six treatments of IBA (1000, 2000, 3000, 4000, 5000, 6000ppm) and one with control (without IBA) were applied at base of hardwood cuttings (6mmØ) of different litchi cultivars. Statistically analyzed data showed that root induction, root growth and survival of rooted cuttings was significantly influenced by IBA concentrations, litchi cultivars and their interaction at p<0.01. The interaction of 5000ppm IBA with “Gola” was found appropriate for development of heavier (10.2±0.57gm), longer (27cm) and more number of roots (6.4±0.81) compared to all other cultivars. Moreover, considerable difference was observed for root ability among all litchi cultivars tested as “Gola” produced maximum, longer and heavier roots with less mortality rate compared to all other cultivars.
