Abstract

The present investigation conducted field trial during 2017-18 at research orchard of Horticulture, collage of agriculture Gwalior in sandy loam to clay loam soil. The influence of adventitious roots and survivability on air layers of Guava (Psidium guajava L) Cv. Gwalior 27 with the add of different coloured poly wrappers. The experiment comprising four sources of poly wrappers (White, Black, Blue and Red) were lead out in randomized block design with 3 replications. The result reveled that maximum value of callus formation (0.25mm), rooting percentage (83.73%), no of primary adventitious roots(11.73), no of secondary adventitious roots (38.58), length of roots (4.17 cm),diameter of roots (0.34mm), fresh weight of roots (1.23 g), dry weight of roots (0.49g), survival percent (64.9%), length of shoot (22.2 inches), no of new sprouts (4.22), no of leaves (11.29) was observed in red coloured poly wrappers. The highest value of all parameters was recorded under red coloured poly wrappers.
