| dc.description.abstract | The study was conducted during February to October, 2003 in the experimental block of Deptt. of Horticulture, G.B. Pant University of Agri. & Tech., Hill Campus, Ranichauri (Tehri Garhwal), Uttaranchal, situated at 30o15‟ North latitude and 70o50‟ East longitude and an altitude of about 2000 m amsl. The experiment was arranged in Factorial Randomized Block Design with two varieties viz., „Chaubattia Anupam‟ and „Tydeman‟s Early Worcester‟ and twelve dates of harvesting at different stages of maturity. The results of the experiment showed that the leaf emergence (20th March) and flowering (31st March) was recorded earlier in „Chaubattia Anupam‟, while the cultivar „Tydeman‟s Early Worcester‟ showed delayed leaf emergence (24th March) and flowering (4th April). The cultivar „Chaubattia Anupam‟ showed slightly better performance in respect of annual extension of shoot growth (22.16 cm) and fruit set (31.98%), while the cultivar „Tydeman‟s Early Worcester‟ showed significantly higher bloom density (53.79%). At harvest, the „Chaubattia Anupam‟ fruits attained green colour with slight tinge of red on the surface in contrast to „Tydemans‟s Early Worcester‟ showing the reddish purple skin. Picking maturity in „Chaubattia Anupam‟ and „Tydeman‟s Early Worcester‟ were exhibited with the respective values of 9.36 and 7.49 lb/inch2 (firmness), 13.15 and 14.26oBrix (TSS), 10.23 and 8.97 mg/100g (ascorbic acid), 0.16 and 0.39% (titratable acidity), 8.98 and 9.70% (sugars) and 30.81 and 27.88% (juice content). The fifteen-year-old trees of apple cultivars „Tydeman‟s Early Worcester‟ resulted in a slightly higher yield potential per tree than Chaubattia Anupam. On the basis of the experimental results, it may be concluded that in both the apple cultivars under study i.e., „Chaubattia Anupam‟ and „Tydeman‟s Early Worcester‟ the 21st of July was observed to be the date of optimum picking maturity under Ranichauri or similar conditions in the Uttaranchal hills. Individually, it was also observed that the optimum picking maturity was attained after about 105 and 98 days from full bloom in the cultivars „Chaubattia Anupam‟ and „Tydeman‟s Early Worcester‟, respectively. | en_US |
