Abstract:

Tuberose is one of the important commercially cultivated loose flower crops known for its fragrant white flowers. The area under the cultivation of tuberose is being increasing among the farmers. But, the availability of quality planting materials and high cost for the healthy bulbs remains a great hindrance for tuberose cultivation. Hence, an investigation was carried out at the Department of Floriculture and Landscaping, Horticultural College and Research Institute, Tamil Nadu Agricultural University at Coimbatore during 2018-2019 on tuberose with the objective of standardizing the planting materials for mass multiplication in tuberose. The treatment details are mother bulbs are divided into different parts and also treated with GA3 at different concentrations. Various morphological observations were recorded during nursery stages viz., Days taken for sprouting, plant height, number of leaves per bulb, days taken for 70% sprouting (days), number of sprouts per bulb, leaf length (cm), leaf width (cm), root length (cm), number of roots per bulb, sprouting percentage (%). This study revealed that, at nursery stage, bulbs cut into two halves (P2) showed minimum number of days taken for sprouting (4 days).Days taken for 70% sprouting recorded minimum days (4days) for bulbs cut into two halves (P2). Maximum plant height of 28.35 cm was observed in bulbs cut into four halves (P4) at 60 DAP in nursery. At 60 DAP, maximum number of leaves (5.70) was recorded in whole bulbs (P1).Maximum leaf length of 26.55 cm was observed in bulbs cut into four halves (P3) in nursery at 60 DAP. Bulbs cut into two halves (P2) was showed highest number of sprouts (90) at 60 DAP. Bulbs cut into two halves (P2) was reported highest plant vigour (3885) at 60 DAP. Maximum relative growth rate (0.016 mg/g/day) was recorded in bulbs cut into two halves (P2) at nursery stage.


Keywords: Tuberose, bulbs, gibberellic acid, sprouting percentage, growth.
