Mango can be raised from seed or propagated vegetatively. Several methods of vegetative propagation have been tried with varying degrees of success.Propagation from seed, though easy and cheap, is unable to perpetuate characters of the parent tree because most commercial varieties in India are cross-pollinated and mono embryonic. Plants also take more time to bear fruit. However, it is essential to raise seedlings to be used as root stocks. We will focus various methods of grafting used in ‘Mango Grafting’. In this part we will understand the simple techniques about ‘Stone Grafting’.
Stone Grafting :
- Stone grafting is a simple, cheap and quick method of mango propagation with a success rate of 75-80%.
- For this purpose, stones should be sown in June-July on raised beds of size 1×3 m. The beds should Be prepared by mixing soil and FYM in the proportion of 2:1.
- After germination, seedlings with tender stems having coppery leaves are lifted with stones still attached.
- The roots and stones are dipped in O.1 per cent Carbendazirn solution for 5 minutes after washing the soil.
- The seedling stems are headed back leaving 6-8 cm long stem.
- A 4-6 cm longitudinal cut is made running down through the middle of the stem.
- A wedge shaped cut starting on both sides is made on the lower part of scion stick.
- The scion stick should be 4-5 months old and 10-15 cm long containing plumpy terminal buds.
- The scion stick is then inserted in the cleft of the seedlings and tied with polythene strips.
- The grafts are then planted in polyethylene bags containing potting mixture.
- The bags are then kept in the shade protecting from heavy rain.
- The scion starts sprouting 15-20 days after grafting.
- Care should be taken to remove the sprouts on the root stocks below the graft union during this period.
- July is the most suitable month for stone grafting.
