dc.description.abstractThe present investigation was carried out to assess the optimum storage temperature for garlic (Allium sativum L.) with minimum deterioration and also for the most promising genotype on the basis of morpho-physiological and biochemical parameters. Garlic genotypes (PG-17, PG- 18, PG-29, PG-46 and PG-48) were kept in three storage temperatures; 0°C, 15°C and room temperature for four months for evaluation of various parameters and then planted to evaluate their growth performance. Temperature and months of storage had a decreasing influence on garlic genotypes. PG-18 was found to be a promising genotype irrespective of temperature storage conditions due to its better performance than other genotypes in morphological properties prior to storage such as bulb diameter (4.5cm), neck diameter (2.7cm), bulbing ratio (0.6), bulb’s fresh weight (28.7g) and dry weight (17.5g), number of cloves per bulb (24.3). PG-18 also retained maximum biochemical composition till end of storage such as total phenols (10.5 mg/g DW), flavonoids (0.59 mg/g DW), ascorbic acid (5.70 mg/g DW), total soluble sugars (17.25 mg/g DW) and reducing sugars (12.71 mg/g DW). Also, genotype PG-18 had highest germination percentage (66.93%), maximum vigour index II (2580) and highest survival percentage (66.45%). Room temperature storage was found to be the optimum storage condition for garlic bulbs as garlic of room temperature performed better than other temperature stored garlic by the end of storage in case of compactness, bulb’s fresh weight (14.86g) and dry weight (8.86g), total phenols (10.46 mg/g DW), ascorbic acid (5.12 mg/g DW) and total soluble sugars (11.88 mg/g DW). Also, room temperature stored garlic, on subjecting to germination, had highest germination percentage (77.01%) and survival percentage (88.40%), maximum vigour index II (2717) and more plant fresh weight (51.40g) , dry weight (21.49g) and height (69.72 cm) than 15°C garlic.en_US
