Physiological Response of China Aster [Callistephus chinensis (L.) Ness] under Shade Net Conditions

Abstract

The present investigation was carried out during the year 2017-18 at College of Horticulture, Dr. Y.S.R Horticultural University, Anantharajupeta, Y.S.R. Kadapa Dist. of Andhra Pradesh. The experiment consisted of 7 China aster genotypes, laid out in randomized block design with four replications under 50 per cent shade net condition. Significant variations were observed among different genotypes with respect to physiological and biochemical traits. Among the genotypes, Arka Archana recorded highest leaf area plant-1 (204.58 cm2 , 1297.89 cm2 and 2689.49 cm2 ), biomass (3.50 g plant-1, 16.00 g plant-1 and 33.00 g plant-1) and LAI (0.228, 1.443 and 2.990) at 30, 60 and 90 DAT. Arka Archana also recorded maximum AGR (0.425 g day-1) and SPAD value (44.26) at 30-60 DAT interval, LAD (25.04, 66.46 days) at 30-60 and 60-90 DAT interval. While highest LAR (100.37cm2 g-1, 138.13cm2 g-1 at 60, 90 DAT) and protein content (40.50 μg g-1, 133.00 μg g-1 in leaves and flowers) was observed in Arka Kamini. However, maximum anthocyanin content of 207.40 mg 100 g-1 was recorded in Local violet and highest AGR at 60-90 DAT interval (0.790 g day-1), protein content in seeds (652.00 μg g-1) was registered in genotype Arka Aadya. The genotype Arka Shashank recorded the highest leaf area ratio at 30 DAT (65.05 cm2 g-1).
