Depotting and Transplanting of Carnati<strong>on</strong> into Medium<br />

The propagati<strong>on</strong> by vegetative lateral shoots of the flowering plants should be<br />

avoided. Since disease are easily perpetuated in this type of propagati<strong>on</strong>. Offsprings<br />

produced by this method have a declining plant vigour and productivity. In order to<br />

produce disease free plants, stock plants should be grown <strong>on</strong> raised benches in<br />

pasteurized media. These plants should be kept in vigorous and vegetative c<strong>on</strong>diti<strong>on</strong>s and<br />

maintained by drip irrigati<strong>on</strong> to keep foliage dry. Plant should be sprayed frequently to<br />

prevent foliage disease and insect damage. Stock plants should be used <strong>on</strong>ly for <strong>on</strong>e<br />

seas<strong>on</strong> of cutting producti<strong>on</strong>.<br />

Mass Scale Producti<strong>on</strong> of Roses:<br />

Roses can be propagated by seeds, cuttings, grafting and buddings. Seed propagati<strong>on</strong><br />

is used by rose breeder for the development of new varieties whereas the T-budding is<br />

used for commercial producti<strong>on</strong> of the plants. The budding is d<strong>on</strong>e over the rooted root<br />

stock of Rosa odorata which is most comm<strong>on</strong>ly used root stock in India. Some times<br />

Rosa indica, R. multiflora are used for the producti<strong>on</strong> of rooted root stock and further<br />

budding. R. multiflora is a popular rootstock in South India.<br />

Producti<strong>on</strong> of Rootstock of Roses:<br />

The 25-30 cm l<strong>on</strong>g semi-hard wood cuttings are planted slanting in well prepared<br />

beds during December to February from rootstock mother plant. The cuttings are planted<br />

at 45 0 with the spacing of 30x15 cm. The field is irrigated as so<strong>on</strong> as the cuttings are in<br />

place to settle the soil around the base. After 20-30 days of planting the rootstock sprout<br />

and grow. During this period adequate soil moisture should be maintained. The moisture<br />

stress can cause the wilting am<strong>on</strong>g the cuttings. Proper care is practiced in field beds up<br />

to June.<br />

Lifting of Rootstock of Roses:<br />

The rooted cuttings are lifted during 15th July to 30th July and planted in budding<br />

block/ polythene bags for budding. The rooted rootstocks are pruned up to the height of<br />
