Abstract:

Performance studies of different clonal rootstocks of Prunus species were undertaken in the Departmental field of Fruit Breeding at Dr YSP UHF, Nauni-Solan (Himachal Pradesh). The experimental plant material was comprised of three clonal rootstocks viz., Myrocal (P. cerasifera), Julior (St. Julien x Pershore) and Jaspi (Methley x P. spinosa) introduced from France and planted in the experimental farms. Observations were recorded on one year old plants on the various growth characters(growth habit, plant height (m), plant spread (m), trunk girth (mm), number of branches per plant), foliage characters (leaf bud burst time, leaf area (cm2), leaf shape, time of leaf fall), physiological characters (stomatal density and size (µm), chlorophyll content (mg/g) and cold hardiness. With respect to growth characters plant height (2.35 m), trunk girth (27.15 mm), plant spread-NS (1.23 m), plant spread-EW (1.19 m) and number of branches per plant (8.67) in Myrocal was significantly higher from those of Julior and Jaspi, however, all the three rootstocks exhibited erect growth habit. Early leaf bud burst and leaf fall was noticed in Julior rootstock i.e. 1st - 2nd week of March and 2nd - 3rd week of November. Maximum stomatal density per microscopic field was recorded in Myrocal (34.29) alongwith maximum stomata length (27.86 m), breadth (17.09 m) and chlorophyll content (2.91 mg/g). Leaf shape in all the three clonal rootstocks studied was observed as ovate, obovate and obovate in Myrocal, Julior and Jaspi, respectively. Mean per cent electrolyte leached out was maximum (35.93) in Myrocal followed by 33.89 per cent in Julior and 32.23 per cent in Jaspi which was statistically significant. On the whole, all the three rootstocks survived well and shown optimum growth.
