Abstract
The present investigation entitled on “Studies on the success and survivability
of grafts in different varieties of guava by soft wood grafting under different growing
conditions” was carried out during the year 2015-16 at University of Horticultural
Sciences, Bagalkot. The results of the investigation revealed that the highest graft
success (77.38 %), number of sprouts (3.83), number of leaves (16.91), sprout length
(13.77 cm), scion diameter (6.36 mm), graft height (50.90 cm), root length (31.25
cm), root mass (27.06 g) and per cent graft survival (68.96 %) were noticed in mist
house followed by shade house. While, the minimum number of days for graft take
(14.97) was recorded in mist house followed by open condition.
Among the varieties, the highest graft success (85.74 %), number of sprouts
(4.34), number of leaves (16.19), sprout length (14.11 cm), scion diameter (6.75 mm),
graft height (52.24 cm) root length (30.93), root mass (28.76 g), per cent graft
survival (73.39%) were recorded in var. Sardar and also recorded minimum number
of days required for graft take (14.18).
Among the interactions, highest number of sprouts (5.17), sprout length (15.33
cm), scion diameter (8.15 mm), graft height (53.07 cm), root mass (34.58 g) were
recorded in var. Sardar when the grafts were kept in mist house followed by shade
house. However, graft success of 95.28 % was recorded in Sardar under mist house
followed by open condition.
