    Provenance Variation in Seed and Seedling Traits of Jamun (Syzygium cumini, Skeels) in Uttar Kannada District
    (UAS, Dharwad, 2013) Lokannavar Rakesh; H. Shivanna
    The study on “Seed source variation in seed, germination and seedling attributes of Jamun (Syzygium cumini Skeels) in Uttar Kannada district of Karnataka” was conducted at college of Forestry, Sirsi. The study was laid out by following completely randomized design with eight treatments (seed sources) and three replications. The maximum fruit length (21.26 mm), fruit diameter (14.79 mm), fruit test weight (370.71 g) were recorded in Mundgod seed source. Seed length (15.20 mm), seed width (8.42 mm) and test weight (53.25 g) were recorded highest in Mundgod seed source. However Sirsi seed source recorded the least for both fruit and seed parameters. Among the fruits collected from different seed sources, pulp weight, pulp content and pulp to seed ratio were 2653.25 g 2.46 g, 74.46% and 65.13 recorded highest in Mundgod seed source. Maximum germination was recorded in Mundgod seed source (90.66%) and least was noticed in Sirsi seed source (69.33 %). At 120 days after germination, maximum seedling height was recorded in Mundgod seed source (47 cm) and least was in Sirsi seed source (40.63cm). Similar trend was observed for collar diameter in Mundgod and Sirsi seed sources. The shoot length and root length traits were higher in Mundgod seed source (48.16 cm and 24.07 cm) at 120 days after germination and lowest was in Sirsi seed source (37.23cm and 17.36 cm).The highest fresh shoot biomass (10.25 g) was recorded for Mundgod followed by Yellapur seed source (9.25 g), least was in Sirsi seed source (5.13 g). Thus Mundgod seed source emerged to be most promising one.
