Abstract:
Grape (Vitis vinifera) is the most important garden crop all over the world. Multiplication and breeding of most important garden and crop plants is based on the cell and tissue culture. Beside the medium composition, the incubation conditions also require to be optimized, too. Important factors in physical environmental of culture are including light, temperature and gas exchanging. The light plays a key role in the range of plant growth activation and is used as a source of energy in the photosynthesis process. Then it must be optimized for the most plant performance. In this study auxiliary buds of grape cv. Crimson Seedless have been grown in treatment of red (622-780 nm), blue (455-492 nm) and visible light (400-700 nm) with two intensity of 5000 and 2500 lux. The fastest growth of axillary bud is referred to the range of the red and visible light with 2500 lux (46.77 hour) and the most axillary bud growth was observed in the range of red light (65.77 mm). In the blue light the developed axis was the strongest. The rate of axillary bud photosynthesis in intensity 5000 lux (38.33 mm) achieved to the level of light saturation, and then dynamic light inhibitions )photoinhibition) and chronic were observed in this treatment.
