Title

Effects of long-day treatment using different supplemental light intensities on quantitative and qualitative traits of Rosa hybrida Dolce vita

Pages

  403-412

Abstract

 In prder to investigate the effect of long-day treatment during autumn and winter on quantitative and qualitative characteristics of Rosa hybrida ‘ Dolce vita’ , an experiment was conducted in completely randomized design with nine replications. Rose bushes were treated with increasing length of photoperiod to 16-h under six levels of light intensity includes 0, 85, 170, 255 and 340 μ mol m-2 s-1 using HPS lamp and 85 μ mol m-2 s-1 using LED lamp. Important factors of quantitative and qualitative yield such as shoot length, stem diameter, time of harvesting, renewal bud formation, quality index and vase life were affected by supplemental light treatments. Using supplemental light, the average time required for harvesting the flower was around five days lesser than the control plants. The highest number of renewal bud formation was observed in light intensity of 85 μ mol m-2 s-1 using HPS lamp, respectively. In many traits such as plant height and stem length, stem diameter under flower, leaf number, leaf length and width, fresh and dry stem weight, flower quality index and vase life, 340 μ mol m-2 s-1 light intensity was the best treatment.
