The paper summarizes the results of ischolar_maining of juvenile cuttings of Chir Pine (Pinus roxburghii Sarg.). Cuttings emanating from 9 clones of P. roxburghii. (UPTSB-14 (Bhasla), HPSNR-5 (Nurpur), UPBER-5 (Berinag), UPKAL-10 (Kaligarh), UPPAT-I094 (Patwadangar), UPTSS-3 (Sikanderdbarl, UPDNH-770 (Dhanari), UPBER-368 (Berinag) and UPDNH-81 (Dhanari) were treated with different concentrations of IBA viz. 1000 ppm, 2000 ppm, 3000 ppm and 4000 ppm and planted in vermiculite under mist condition. Significant differences in ischolar_maining percentage and other ischolar_main parameters were observed between the clones. Among the four concentrations of IBA tried, 4000 ppm proved to be the best. 100% ischolar_maining was observed in three clones viz. UPTSB-14, UPKAL-10 and UPPAT-1094.

Abstract


The paper summarizes the results of ischolar_maining of juvenile cuttings of Chir Pine (Pinus roxburghii Sarg.). Cuttings emanating from 9 clones of P. roxburghii. (UPTSB-14 (Bhasla), HPSNR-5 (Nurpur), UPBER-5 (Berinag), UPKAL-10 (Kaligarh), UPPAT-I094 (Patwadangar), UPTSS-3 (Sikanderdbarl, UPDNH-770 (Dhanari), UPBER-368 (Berinag) and UPDNH-81 (Dhanari) were treated with different concentrations of IBA viz. 1000 ppm, 2000 ppm, 3000 ppm and 4000 ppm and planted in vermiculite under mist condition. Significant differences in ischolar_maining percentage and other ischolar_main parameters were observed between the clones. Among the four concentrations of IBA tried, 4000 ppm proved to be the best. 100% ischolar_maining was observed in three clones viz. UPTSB-14, UPKAL-10 and UPPAT-1094.
