Abstract
An experiment on guava propagation as affected by different layering methods and growth regulators was conducted at the Horticulture Farm, Bangladesh Agricultural University, Mymensingh, from February 2002 to January 2003. The two factor experiment consisting of three layering methods viz, mound, trench and air layerings and ten growth regulator treatments viz. 2000, 2500 and 3000 ppm IAA; 2000, 2500 and 3000 ppm IBA; 200, 300 and 400 ppm GA3 and a control was laid out in the Randomized Complete Block Design (RCBD) with 4 replications. Methods of layering showed significant effect on success of rooting, survivability and most of the growth parameters. The highest percentage of success in rooting (84.23%) was obtained from mound layering. Trench layering showed the highest percentage of (87.82%) survivability and also showed the best performance regarding all growth parameters except number of shoots per plant. Among the three methods, air layering showed the poorest performance. Growth regulator treatments had significant effect on almost all parameters. Maximum number of shoots/plant (5.75), highest success in rooting (94.83%), maximum number of roots (40.00) per layer, longest roots (21.64cm), maximum fresh (37.49g) and dry (18.96g) weights and the highest survival percentage (95.35%) were recorded when IBA (2500 ppm) was used. Combinedly, trench method of layering treated with 2500 ppm IBA gave the best result incase of number of shoots per plant, fresh and dry weights of roots. The highest percentage of success in rooting and the highest survival percentage were recorded when 2500 ppm IBA was used in both trench and mound layerings.
