dc.description | The present investigation was carried out at the Polyhouse of the Citrus Nursery Block, Department of Fruit Science, College of Horticulture and Forestry, CAU (Imphal), Pasighat, Arunachal Pradesh during the year 2019-20. The experiment was laid out in Completely Randomised Design with 6 (six) treatments in four replications. | en_US |
dc.description.abstract | The treatment details of the present experiments were T1 (Karnakhatta), T2 (Rangpur lime), T3 (Samphola), T4 (Volkamariana), T5 (Rough lemon) and T6 (Tasi). The analysis of variance revealed that there was significant variation among the different species. The experimental results showed that treatment T1 (Karnakhatta) exhibited maximum for most of the parameters i.e., extent of polyembryony (36.57 %), plant height (42.00 cm), girth of shoot (5.30 mm), rootstock vigour index (2373.50) root volume (10.33 ml), fresh and dry weight of root (5.08 and 4.62 g) and shoot (6.05 and 5.40 g). T2 (Rangpur lime) had maximum number of leaves (31.50), chlorophyll content a, b and total (2.46, 1.00 and 3.46 mg/g respectively), germination vigour index (8.920) and percentage of NPK in plant leaf sample. Treatment T3 (Samphola) showed maximum germination percent (80.50 %). The highest number of primary roots (72.50) was recorded in treatment T5 (Rough lemon). In this study, T1 (Karnakhatta), T2 (Rangpur lime) and T4 (Volkamariana) recorded high germination percentage, germination vigour index, polyembryony, nutrient uptake, plant height, girth of stem and chlorophyll content. Therefore, it may be concluded that these citrus species have the potentiality as rootstock in North Eastern Region with respect to growth, nutrient uptake and early graftability. | en_US |
