Abstract
An investigation on “Effect of media composition on seed
germination, seedling growth and its effect on grafting in mango
(Mangifera indica L.)” was carried out during July 2010 to February 2011
at Division of Horticulture, University of Agircultural Sciences, GKVK,
Bangalore. The experiment was laid out in factorial randomized complete
block design with three Mango varieties involving nine compositions of
media (soil, sand, compost, coirpith and vermicompost in different ratio)
with control.
Among the varieties, Nekkare recorded statistically significant
difference in time taken for first seed to germinate, time taken for 50 per
cent germination, leaf area, height of seedlings, girth of seedling, length
of longest secondary roots, length of sprout, graft success, time taken for
sprouting and height of grafted plant. The maximum germination
percentage, number of leaves, length of primary root and number of
secondary roots was recorded in Neelum.
The treatment soil: sand: compost: coirpith (1:1:1:1) recorded the
minimum days for first seed to germinate (21.66 days), minimum time
for 50 per cent germination (30.77 days), maximum germination
percentage (45.55%), maximum height of seedling (28.97 cm), maximum
girth of seedling (0.83 cm), highest number of secondary roots (25.55)
and minimum days (10.77 days) for first sprouting.
The number of leaves (15.03), leaf area (54.82 cm2), number of
branches (2.21), graft success (94.43 %), length of sprout (9.33 cm) and
height of grafted plant (17.38 cm) was maximum in treatment soil: sand:
compost: coirpith (2:1:1:1).
