Rose is called as the Queen of flowers as well as King of flowers. Rose is a very important flower crop cultivated in the country. Rose is propagated by different methods like cutting, shield budding, grafting etc. The rootstock like Rosa indica, Rosa multiflora, and Edward rose are commonly used for rose propagation. Introduction
Propagation Method: Cutting This Cutting method of propagation is used for propagation of rose rootstocks, miniature roses, shrub roses, climbing roses and ramblers. Newly matured stem are selected for such type of propagation. The stem is cut in such a way that each cuttings has 4-5 buds. Root promoting hormones like IAA, IBA are used for rooting the cuttings. Rooting period varies with type of cuttings, growing media, season of cutting and growth regulators treatment.
Shield or T-Budding is most commonly used method of rose propagation. T shaped incision is made on the selected rootstock. Bud is inserted into the incision and then firmly tied with a plastic film. Budding should be preferably done on lowest part of the rootstock. Union requires as long as 3-4 weeks after which the side branches of rootstock are removed. When new shoot from the grafted bud is growing about 10 cm long, the portion of rootstock above union is cut off and polythene tape around the union is removed. Shield or T-Budding:
Shield budding: T-shaped incision on rootstock Insertion of bud on rootstock Tying of bud on rootstock
Layering: This propagation method is limited to Climbing and Rambling roses. They can be propagated either by Ground Layering or Air layering. Air Layering in Rose
Rootstocks Rootstocks:Commonly used rootstocks in rose are: Rosa borboniana, Rosa multiflora, Rosa indica. 1.Rosa bourboniana (Edward Rose): It is most popular rootstock used extensively in India for budding standard roses. 2. Rosa indica (var. odorata): It is a large climbing shrub used for greenhouse roses which is easily propagated from cuttings. It is well adapted to dry or wet soil conditions, can withstand high soil pH and is resistant to powdery mildew and many insect pests. In India, it has been recommended for Northern plains.
Rootstocks 3. Rosa multiflora: It is a native of China and Japan and introduced in India in 1872. It is widely used root stock for outdoor roses which can be easily propagated by cuttings. It is adaptable to wide range of soil and climatic conditions. It recommended for Bihar, Bengal and hilly areas. Rosa multiflora
