apple cultivars to assess the physico-chemical changes and shelf-life at ambient storage conditions for 49
days. The physiological loss in weight, TSS, reducing sugars, total sugars, non-reducing sugars and fruit
decay percentage increased, while fruit firmness, titratable acidity, ascorbic acid content and organoleptic
score decreased during storage in all cultivars. Cultivar Skyline Supreme exhibited lowest physiological loss
in weight (7.77%), highest TSS (14.93 °B) and organoleptic score (7.19) than other apple cultivars. However,
the cv. Red Chief exhibited highest ascorbic acid (12.32 mg/100 g), reducing sugars (8.89%) and total sugars
(10.59%) and the cv. Bright-N-Early exhibited highest fruit firmness (8.18 lb/in2
) and lowest fruit decay (5.05%)
than other apple cultivars. Conclusively, Skyline Supreme, Red Chief and Bright-N-Early have better shelf-life
than other apple cultivars under ambient storage conditions.Not Availabl

Physico-chemical characterization of wild apple (Malus baccata) in Kumaon hills of UttarakhandA survey was conducted in Kumaon hills of Uttarakhand (India) for evaluation of physico-chemical
characteristics in wild apple (Malus baccata). During the survey, total five variants of wild apple were
collected and assessed for their important physico-chemical traits. A considerable variability in physicochemical
characteristics was observed among the variants. Majority of the variants are small (<2.5 m) to
large (>5 m) in tree size, produces medium size (15-30 mm) fruits which are round to globose in shape,
yellowish red to dark red in colour and mid (August-September) to late (October-November) in maturity.
The highest leaf length (7.54 cm), leaf width (4.90 cm) and leaf area (64.69 cm2) were recorded in Collection-
4, while the lowest leaf length (6.10 cm) and leaf width (3.30 cm) were recorded in Collection-1. The highest
fruit length (31.53 mm), fruit width (38.45 mm), fruit weight (28.15 g), total sugars (8.94%), reducing sugars
(6.41%), total anti-oxidant activity (32.65 mMTE/L), seed length (7.32 mm), seed width (4.06 mm) and seed
index (3.18 g) were recorded in the Collection-5, while lowest leaf area (48.64 cm2), fruit length (8.68 mm),
fruit width (9.09 mm), fruit weight (0.45 g), total sugars (2.83%), carotene content (84.08 Îźg/100 g), total
anti-oxidant activity (10.05 mMTE/L), seed length (4.59 mm), seed width (2.09 mm) and seed index (1.18 g)
were recorded in Collection-2. The most of the physico-chemical characteristics were found superior in
Collection-4 and Collection-5 as compared to other wild apple collections.Not Availabl
