 ABSTRACT

The present investigation was carried out at orchidorium, Regional Horticultural Research and Extension Centre, University of Horticultural Sciences campus, GKVK, Bengaluru during October 2015 to June 2017. The results indicated a significant influence on color intensity of L* a* b* on fresh petals of each variety of Dendrobium orchid grown under different environment conditions. Maximum brightness of L* value in petals (49.10) and red to green of a* value (30.47) was recorded in flowers grown under polyhouse condition (G1) and it was minimum under shadehouse (G2). Highest flower color from yellow to blue b* value (15.74) was observed in polyhouse condition (G1) than the shadehouse condition (G2) (14.42). With respect to Dendrobium varieties, maximum brightness of color intensity (85.63) was recorded in var. Charming White (V3) and it was minimum color intensity (22.41) was found in var. Mona Red (V2). Highest red color development (65.51) was recorded in var. Mona Red (V2) followed by var. Sonia-17 (V6) and lowest in var. Big White (V7) (-3.93). Maximum development of yellow color (35.01) was recorded in var. Burana Jade (V6) and minimum intensity of blue color was recorded in var. Mona Red (V2) and var. Bubble Gum (V4) (-4.84 and -6.35 respectively). Highest chlorophyll content in leaves (36.21, 41.89 and 47.69 spad units respectively) was recorded under plants grown under polyhouse condition (G1) and lowest (33.82, 39.39 and 44.85 spad units respectively) was recorded under shadehouse condition (G2).Maximum chlorophyll content in Dendrobium leaves (57.08 spad units) was found in var. Sonia-17 (V7) and it was observed minimum (38.86 spad units) was noticed in var. Charming White (V3).

Key words:Color intensity, Chlorophyll, Dendrobium.
