Standardization of Nursery techniques of Five Prominent Indigenous species (Capparis spinosa, Colutea nepalensis, Caragana geraradiana, Ribes orientale, Cratagus songarica besides Eleaegnus angustifolia, Hippophae rhamnoides and Rosa webbiana ) of Cold desert.

Principal Investigator: Dr. K.S.Kapoor, Scientist-F

In Case of Eleagnus angustifolia the new growing shoots of 20 to 30 cm length collected from the healthy mature plants during April treated with 5000pm to 6000pm concentrations of IBA using quick dip method in soil and sand medium gave more than 90% rooting in Poly- house. Whereas 6000 ppm to 7000 ppm concentrations in open nursery conditions in soil medium gave more than 70% rooting. After rooting, all the plants kept in beds in Open nursery during next growing season for hardening. The stock gets ready for out planting in the third growing season. In case of the Rosa webbiana, the seeds must be sown immediately in poly-house for best germination (80%) and (60%) in open nursery condition whereas the germination declines if the seeds are sown during the following March/ April. The Plant can also be propagated by root cuttings of 12- 15 mm thickness. However, one should prefer the propagation of Plant through seeds. The seeds of Colutea nepalensis (Sims) mature by mid of September hence, should be collected and processed. Sowing should be done during April in the nurseries to obtain maximum germination (upto80 percent) in poly house during first growing season and during the second growing season shifted to open nursery condition in the beds for subsequent hardening. The stock is ready for out planting I the third growing season.
