Abstract
Treatments were executed in three factor factorial CRD(Completely Randomized Design)with three replications. Different rootstocks viz., Rough Lemon (Citrus Jambhiri Lush.), Rangpur Lime (Citrus limoniaUsbek), Khasi Mandarin (Citrus reticulata Blanco),Volkamer Lemon (Citrus volkameriana) and Pummelo (Citrus grandisOsbeck) and different methods of budding (‘T’ budding and Modified Chip budding) were used for budding in Khasi Mandarin in February, April and March.Interaction of budding time, methodsand types of rootstockshowed maximum bud take (93.33%) when Modified Chip budding was performed on Rough Lemon and Rangpur Lime during February. Maximum budding success (93.33%), length (11.30cm), girth (2.14mm) and dry weight of sprout (2.95g), number of leaves (7.97), Chlorophyll ‘a’,‘b’ and total (0.34, 0.50 and 0.86 mg/g respectively) were recorded when Modified Chip budding was done on Rough Lemon in February. Fresh weight (5.22g) was higher in Rough Lemon budded with both ‘T’ budding and Modified Chip budding during February. Minimum days required to sprout (32.00) and maximum root diameter (8.23mm) were observed on Khasi Mandarin with Modified Chip budding done in February. Maximum leaf area (18.36 cm2) was observed in Rangpur Lime with Modified Chip budding and maximum length of leaf (6.76cm) as well as breadth of leaf (4.47cm) with ‘T’ budding performed during February. Maximum rootstock parameters such as length (32.37cm), number of primary roots (3.33), fresh weight (22.13g) and dry weight (16.22g) were found maximum in Volkamer Lemon with ‘T’ budding done during February along with perimeter of leaf (18.7cm). The maximum root: shoot ratio (29.87) was observed when ‘T’ budding was done on Pummelo in April and minimum (0.43) in ‘T’ budded Rough Lemon in April.. Therefore, it is concluded that the Modified Chip budding is the best method of budding that can be performed during February in Khasi Mandarin using Rough Lemon as rootstock with respect to bud take, budding success and growth of sprout.
Description
Khasi Mandarin (Citrus reticulata Blanco), an excellent quality Mandarin grown in North East India has high export potential. In North-East, Khasi Mandarin is widely adaptable but the productivity is quite low due to the fact that they are mainly of seedling origin. Thus, multiplication with suitable rootstock through budding, which is faster and efficient, is promising to boost its cultivation in this region. With this backgroundthe present investigation was undertaken 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 2021-22.
