Effect of planting densities on growth, flowering and postharvest quality of cut spike in tuberose (Polianthes tuberosa) cv. 'Single'.

The effect of seven plant spacing, viz. 30x30, 30x20, 30x10, 20x20, 20x12.5, 20x10 and 20x8.5 cm, on vegetative growth, flowering and postharvest quality of cut spikes in tuberose cv. 'Single' was investigated at Bangalore, Karnataka, India, during 1997-98. Wider spacing resulted in longer rachis and heavier individual florets. Closer spacing produced higher yield of cut flower and loose flower per plot basis. Wider and closer spacing have vice versa effect on above floral parameters. Rest of the studied parameters namely, plant height, number of leaves per clump, spike length, diameter of second floret, flowering duration under field condition and number of florets per spike and their corresponding weight and postharvest quality of cut flower were not influenced significantly by the plant densities.
