Abstract:
A field experiment was conducted at the Horticulture Farm Bharregaon under Pt. K.L.S. College of Horticulture and Research Station, Rajnandgaon (C.G.), during Rabi season of 2020-21, to evaluate the “Effect of plant growth regulators on air layering in guava (Psidium guajava L.)”. Totally 11 different treatments and 03 replication consisting of different growth regulators have been tried. Among the effect of different practices, the application enhanced the root parameters like callus formation (mm), success in rooting percentage, number of secondary roots/ air-layers, length of secondary roots/ air-layers (cm), diameters of secondary roots/ air-layers (mm), fresh weight of roots /air –layers (g) and dry weight of roots/ air-layer (g) were significantly superior in the treatment T₄ (Indole 3 butyric acid- 10000 ppm) and least performance in the treatment T₀ (Dipped in distilled water). There for it may be concluded that treatment T₄ (Indole 3 butyric acid- 10000 ppm) may be prefer for growth regulators on air layering in guava.
