| Abstract:
The effects of blue, black and red shade nets on flowering and biomass production of several cultivars and hybrids of Phalaenopsis were studied. Plants aging from 6 months until the end of cycle and very young plants until the end of the cycle were tested. Flowering of all cultivars and hybrids, except one, was earlier and anthesis was reached sooner when grown under the red shade net as compared to the other two. Number of flowers was higher in plants grown under red shade net. Leaf surface area and the biomass of the leaves and roots were larger for plants grown under the blue shade net than the red and black net. These results suggest that the management of the spectrum can improve commercial characteristics in the Phalaenopsis plants. | |
