dc.description.abstractThe present investigation entitled on “Standardization of grafting time and propagation environment in red pulp guava (Psidium guajava L.) hybrids” was conducted with the hybrids Arka Kiran, Punjab Pink and Punjab Bold during the period 2020-2021 at Fruit nursery, MHREC, University of Horticultural Sciences, Bagalkot. The first experiment were laid out in two factorial completely randomised design with fifteen treatments and two replications to standardize grafting time. Nine treatments and three replications for the second experiment to standardize the propagation environment. Among the five different time of grafting considered viz., November, December, January, February and March for the standardization of grafting time in different red pulp guava hybrids, Arka Kiran grafted on February month took very less number of days taken for first sprouting (4.24 days), maximum number of sprouts (4.37, 4.45 and 4.62), number of leaves per graft (10.25, 14.59 and 18.27 cm), sprout length (2.50, 4.60 and 7.43 cm) at 30, 60 and 90 DAG (Days after grafting) respectively. Whereas, fresh and dry weight of shoot (24.40 and12.92 g), fresh weight of root (13.02 g), survival percentage (99.50 %) at 90 DAG and chlorophyll content (46.25 and 63.10 SCMR) at 60 and 90 DAG respectively has been recorded. Among the three different propagation environmental conditions considered viz., polyhouse, shade net and open field condition for the standardization of propagation environment in red pulp guava hybrids, Arka Kiran placed under poly house condition took least number of days taken for first sprouting (8.34 days), maximum number of sprouts (4.20, 4.33 and 4.40, respectively), number of leaves per graft (10.43, 14.59 and 18.27), sprout length (2.50, 4.60 and 7.43 cm) at 30, 60 and 90 DAG respectively. Whereas, fresh and dry weight of shoot (23.40 and 12.20 g), fresh weight of root (12.00 g), root length (28.26 cm), graft success (94.10 %), survival percentage (89.92 %) at 90 DAG. Whereas maximum chlorophyll content (45.53 and 63.00 SCMR) and the maximum stomatal conductance (339.33 and 391.80 m mol m2 s -2 ) was observed at 60 and 90 DAG respectively when Arka Kiran grafts maintained under open condition.
