    Provenance Variation of Cassia flstula L. for Pod, Seed and Seedling Traits from Agroclimatic Zones of Northern Karnataka
    (UAS, Dharwad, 2013) Renuka Nayak; H. Shivanna
    Cassia fistula, a member of the family Caesalpiniaceae is an important tree with lot of medicinal properties commonly called as ‘Amaltas’. Recently this species is gaining more popularity for its medicinal value. The pods and seeds are economically important part having medicinal properties. With this point in view the present study was carried out in College of Forestry, Sirsi during 2012-2013. The study was laid out by following CRD design with five treatments (provenances) and three replications. The average pod weight and length was 59.28 g, 57.60 cm. The average seed length, seed width, seed test weight and volume was 6.80 mm, 5.96 mm, 16.68 g and 12.18 mm3. Hilly zone recorded the highest for pod and seed parameters. The study was laid out by following factorial CRD with five treatments (provenances) as main treatment and 12 pre-sowing treatment with three replications. Out of twelve different seed treatments tried, the maximum germination percentage (81.47%) was recorded in Cold water soaking for 24 h after that dipping in H2SO4 for 1 min. The other quality indices viz., mean daily germination, peak value, germination value, germination rate of seeding also high in this treatment. Significantly increased the seedling growth attributes was observed in hilly zone viz., seedling height, collar diameter, shoot fresh, root fresh, shoot and root vigour index, shoot to root ratio, total leaf area, relative water content and Chlorophyll content by 38.20 cm, 3.74 mm, 8.50 g, 4.55 g, 3775.80, 1231.39, 2.14, 1358.79 cm2, 90 per cent and 21.90 mg/ g fresh weight respectively at 180 days after planting. The study identifies the Hilly zone as the best provenance for Cassia fistula.
