ABSTRACT
The experiments were carried out at AICRP Floriculture Research Unit, Regional Research Station Wadura. (SKUAST-K) to assess the effects of low temperature storage and duration on flower and bulb production in Asiatic Lilium. Four temperature regimes (Ambient, -40C, 00Cand 40C) and five storage durations (1, 2, 4, 6, and 8 weeks) were studied in cultivar “Elite”. The storage temperatures had significant effect on growth, flowering and bulb characteristics of Asiatic Lilium. Bulbs stored at ambient conditions took minimum days to sprout (5.76). Ambient conditions also recorded maximum plant height (57.80cm) and more leaf number (58.72 plant-1) On the other hand 4 0C recorded minimum days for appearance of flower bud (48.96 days), minimum days to colour break (54.98 days) and earlier anthesis (57.19 days). This temperature regime was also best in producing maximum number of flowers (6.40 plant-1), largest flower (11.91 cm), more number of bulbs (2.75 plant-1), heaviest bulb (61.99 g), maximum bulb diameter (2.94 cm), increased number of daughter bulbs (1.89), maximum diameter of daughter bulbs (0.66 cm), highest scale size (1.22 cm) and finally recorded efficient propagation coefficient (2.75) where as -4 0C.was best in producing maximum number of scales (16.71). The influence of storage duration was significant on vegetative and bulb characteristics. Under 8 week duration, bulbs sprouted earlier (8.03 days). Again 8 weeks duration was superior in case of earliest appearance of flower bud (42.92 days), colour break (47.88 days), flower anthesis (49.82 days) weight of bulbs (80.78g), diameter of bulbs(3.60cm), diameter of daughter bulbs (1.21 cm) and scale size (1.90 cm).On the other hand 1 week duration was best in recording maximum plant height (63.15 cm), more number of leaves (72.99 plant-1), maximum number of flowers (4.45 plant-1), maximum flower diameter (10.25 cm),increased number of bulbs (4.01 plant1), more number of daughter bulbs (2.85), highest number of scales (21.81) and an efficient propagation coefficient (4.01).
