Climate and intercultural operation
a) Climate:
- Cultivated from tropical to temperate region
- Shows deciduous behavior in temperate region whereas ever green in tropical region
- Prefers dry and cool weather during fruit maturation
Â
b) Soil
- Sandy to sandy loam (pH- 7.3)
Â
c) Propagation
- Seed: Seeds dormancy can be broken by keeping the seed in cool environment (1 C) for 4-5 months or dipping the seed in 100-500 ppm GA3
- Cutting: Hardwood and Softwood
- Budding and grafting: V. vinifera cultivars are mostly susceptible to Phyolloxera and nematodes. So, V. rupestris, V. raparia (both phyolloxera ressistance) and V. solonis, V. chamini and V. doahiana (resistance to nematodes), T-buding in Asadh and Chip budding in Chaitra
