Abstract
The present investigation entitled “Propagation Studies in Wild pomegranate (Punica granatum L.)” by hardwood cuttings was carried out at Research Farm, Division of Fruit Science, Faculty of Agriculture, Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu, Main campus, Chatha during the year 2020-21. The aim of this investigation was to standardize the doses of auxins and planting time for inducing maximum rooting and its establishment in wild pomegranate. The experiment was laid out according to randomized block design (factorial) with seven treatment combinations replicated thrice. The root and shoot parameters of wild pomegranate plant such as survival percentage was recorded on 60 days after planting and it was observed that highest average root length (22.37 cm) was observed in cuttings treated with IBA 2500 ppm and planted on 30th January, length of longest root (26.16 cm), minimum number of days to sprout (12.32 days), number of shoots per cutting (4.85), shoot diameter (3.11 mm), leaf area (33.45 cm2), number of leaves (214.00), fresh and dry weight of shoots (18.87 and 12.09g), partitioning coefficient to stems (75.14), and partitioning coefficient to leaves (86.45), partitioning coefficient to root (6.00) visualized to be highest in hard wood cuttings treated with NAA 2500 ppm and total chlorophyll content (55.33 nmol/cm) was highest in cuttings treated with IBA 2500 ppm planted on 15th January. However survival percentage (76.73 per cent), diameter of longest root (1.59 mm), fresh and dry weight of roots (1.11 g and 1.07 g respectively) and length of longest shoot (26.38 cm) were found to be non- significant in this experiment. It can be concluded that from all the studied treatments in wild pomegranate cuttings, IBA 2500 ppm on 30th January resulted in average root length, length of the longest root, minimum number of days taken to sprout, number of shoots per cutting, shoot diameter, number of leaves, leaf area, fresh and dry weight of shoots, partitioning coefficient of stems and partitioning coefficient of leaves, T2D3 (IBA 2500 ppm on 15th January) showed highest chlorophyll content and T5D4 (NAA 2500 ppm on 30th January) recorded highest partitioning coefficient. Whereas, survival percentage, diameter of longest root, fresh and dry weight of roots and length of longest shoot were found to be non- significant.
