Description The study on “Provenance variation studies on fruit, seed and seedling, traits of
Zanthoxylum rhetsa - a tree under high exploitation in Central Western Ghats” was conducted
at college of Forestry, Sirsi. The study was laid out by following completely randomized
design with six treatments (seed sources) and four replications. The fruit length, fruit width,
fruit test weight were 6.09 mm, 4.19 mm and 21.29 g respectively in Sirsi seed source which
was found highest. Seed length, seed width and test weight and volume were 2.84 mm, 1.75
mm and 10.40 g, 0.037 mm3 in Sirsi seed source which was found to be superior from rest of
the seed sources. However Kumta seed source recorded the least for both fruit and seed
parameters. Among the different pre treated seeds, the highest germination percentage was
found to be 45% in boiling water for five min with cow dung treatment for three days,
followed by only cow dung treatment for two days (42%). There was an increase of 68.64 per
cent in mean daily germination due to boiling water for five min with cow dung treatment for
three days as compared to control. Maximum germination was recorded in Sirsi seed source
(45.29%) and least was noticed in Kumta seed source (26.45 %). At 180 days after
germination, maximum seedling height was recorded in Sirsi seed source (37.11 cm) and
least was in Kumta seed source (24.88 cm). Similar trend was observed for collar diameter in
Sirsi and Kumta seed sources. The shoot length and root length traits were higher in Sirsi
seed source (33.45 Cm and 17.01 cm) at 120 days after germination and lowest was in Kumta
seed source (22.65cm and 12.96 cm).The highest fresh shoot biomass (9.43 g) was recorded
for Sirsi followed by Siddhapur seed source (9.05 g), least was in Kumta seed source (8.18
g). Thus it is inferred that for any further Improvement/ breeding work, Sirsi seed source was
found most promising.
