Anthracnose caused by Colletotrichum gloeosporioides (Penz.) Penz. and Sacc. is one of the most important diseases of mango. During survey, the disease samples of fruits affected by anthracnose were collected from Arambakam, Dapoli, Hassan, Hessarghatta, Lucknow, Raichur, Tiruvur and Tumkur, and isolations were made. Studies were conducted to find out the temperature requirement of different isolates by incubating them at 15, 20, 25 28 and 30°C. The study indicated that the temperature of 25°C was found to be good for the growth of Aramkabam, Lucknow and Tiruvur isolates. Maximum growth of Dapoli, Hessarghatta and Tumkur isolates were recorded at 28°C whereas 30°C supported good growth of Hassan and Raichur isolates, nine days after inoculation. As regards to sporulation, Dapoli, Hessarghatta and Raichur isolates were good at 28°C whereas, 25°C supported good sporulation of Lucknow and Tiruvur isolates. Hassan and Tumkur isolates showed moderate sporulation at 28°C and 25°C supported moderate sporulation of Arambakam.© 2010 Academic Journals. Source

A study on the vegetative propagation of Vitex negundo (L.) was conducted in University of Agricultural Sciences, Bengaluru during 2010-11 with a four replicated factorial CRD. Single, double and triple node hardwood cuttings were treated with different growth hormone solutions and observations were recorded. The shoot parameters such as days taken to sprout (9 days), number of sprouts(3.23), length of the longest sprout (20.38 cm), fresh weight (3.6 g) and dry weight (0.88 g) of sprouts and the root parameters like time taken to root (30 days), number of roots (19.05), length of the longest root (21.75 cm), fresh weight (2.37 g) and dry weight (0.67 g) of roots were significantly higher in triple node stem cuttings treated with Indole Butyric Acid 3000 ppm. Thus triple node hardwood cuttings treated with 3000 ppm Indole Butyric Acid (IBA) obtained maximum rooting success. Source

Brinjal were regenerated from callus derived from hypocotyl, cotyledon and root explants of five genotypes, namely Punjab Barsati, Punjab Sadabahar, Jamuni Gola, PBSR-11 and BB-93C on MS medium containing different concentrations of IAA and BAP. A combination of 2.5 mg/l IAA + 0.5 mg/l BAP was found optimum for adventitious shoot induction from all explants. Genotype, explant and genotype x explant interaction showed highly significant effects on organogensis. Among genotypes, PBSR-11 showed maximum response for organogenesis (79.43%). However, among explants, cotyledon was significantly better than hypocotyl and root. Plants regenerated via adventitious shoots were rooted on half-strength MS basal medium in vitro. Source

A field experiment was carried out at the Indian Institute of Horticultural Research, Bengaluru during 2011–12 to study the effect of seed coat removal on seed germination and vigor of polyembryonic mango seedlings. In seed coat removal, the cultivar Muvandan recorded the maximum germination percent (85.4%), extent of polyembryony (2.76), and maximum number of leaves (10.3), whereas Bappakkai recorded maximum plant height (22.4 cm), stem girth (0.64 cm), leaf area (249.2 cm2), fresh weight (18.5 g) and dry weight (8.4 g), vigor index-I (1831.5 cm), and vigor index-II (685.7 g). With respect to treatments, seed coat removal was superior in all of the parameters, namely, initiation of germination (16.7 days), germination percent (78.3%), extent of polyembryony (2.50), plant height (19.5 cm), stem girth (0.62 cm), number of leaves per plant (8.7), leaf area (288.3 cm2), fresh weight (16.2 g) and dry weight (7.3 g), vigor index-I (1559.0 cm), and vigor index-II (581.8 g) compared to seed coat intact. There were no significant differences among the interactions of different treatments and cultivars. © 2016 Taylor & Francis. Source

A field and laboratory experiment was conducted at Indian Institute of Horticulture Research, Bengaluru. Residual cabbage leaves (RCL) were collected after harvesting of heads. The left over leaves were collected and partitioned in to two; one was subjected for blanching and another unblanched. Then the leaves were oven dried at 60°C until they became crisp textured and ground to powder. The powder was used for further preparation of biscuit in different ratios 5, 7 and 10 per cent. The nutrient composition such as protein, carbohydrates, fat, total carotenoids, vitamin C and total antioxidants were estimated for unblanched and blanched RCL powder and their products. Blanching helped in increasing fibre, total carotinoids and total antioxidant activity but there was reduction in vitamin C content. A close perusal of data indicated that with the increase in RCL powder there was increase in all the nutrient components. All the fortified products were evaluated for sensory qualities such as texture, appearance, taste, crispness and overall acceptability for 100 score among different panelists but no significant differences were recorded among the treatments.
