Propagation Techniques of Crataegus crenulata : a Multipurpose Plant of Mid Himalayan Hills

The study standardized the propagation techniques of Crataegus crenulata through seeds and cuttings. Mature pencil thick cuttings were collected and treated with different hormone concentrations (100, 150, 200, 250, 300 nd 350 ppm) of hormones i.e. IBA (Indole -3-butyric acid), IAA (Indole-3-acetic acid) and NAA (Napthelene-6- acetic acid). Sprouting and rooting capacity of the cuttings were assessed under open environmental conditions. Data revealed that IBA 250 ppm significantly enhanced sprouting, rooting and root length as compared to other plant growth regulators and control. The IBA (250 ppm) treated cuttings were found to be best for maximum plant length (189.32cm) and number of branches (6.45) after six months of transplantation in the field. Overnight (12 hr) dipping the cuttings in running water was observed helpful in removing phenolic components. Dipping of seeds in lukewarm water overnight (12 hrs) significantly improved in germination per centage (85-90 %) as compared to control (65-70%). Comparative study indicate that cutting raised seedlings were having edge over seed raised seedlings in terms of plant height and number of branches and being a faster method of multiplication also.
