Abstract
An investigation was conducted on grafting in brinjal during rabi season of 2016-17 with the major objectives of monitoring the changes induced by different rootstock-scion combinations in terms of plant growth and fruit quality of brinjal at ICAR-IIHR.
The experiment was laid out in randomized block design with three brinjal hybrids Mahyco-9, Lalitha and Sharpova grafted onto Solanum torvum Swartz and non grafted were used as control. The effect of rootstock on the agronomic characteristics of the three brinjal cultivars, allow a series of considerations on the feasibility of this technique in the cultivars tested. The grafted plants produced maximum yield than non-grafted ones when grown for the potential economic value. Graft success was recorded about 85 to 87% in all the rootstocks and scion combinations, on an average it was reported 85%. Overall vegetative growth was highest in grafted plants. Maximum plant height was recorded in grafted Mahyco-9. The highest number of branches was recorded in grafted hybrid Lalitha. Number of leaves was recorded maximum in grafted Lalitha. Leaf, stem, root dry weight and leaf area index were recorded maximum in Mahyco-9 and the highest fruit dry weight was recorded in grafted Sharpova. A positive effect of grafting was recorded when Solanum torvum Swartz was used as rootstock. Flowering was early in grafted Mahyco-9 followed by grafted Lalitha. Days taken for 50% and 100% flowering in self rooted and grafted Lalitha took minimum number of days. Fruit set, number of fruits, yield per plant was recorded maximum in grafted Mahyco-9. The highest fruit length was recorded in grafted Mahyco-9 whereas, fruit diameter and volume was recorded highest in grafted Sharpova. Grafted Mahyco-9 performed best in flowering and yield characters when Solanum torvum Swartz was used as rootstock.
Description
Grafting increases yield since plants have strong root system and increased photosynthesis. It was believed that grafting is an effective horticultural approach to improve fruit yield and quality under adequate growth conditions. The positive effect of the rootstock on fruit yield and quality may be dependent on both the shoot and root genotypes making it a difficult task to select the optimum rootstocks. So considering the advantages of grafted plants, study was conducted on “Evaluation of rootstock and scion in brinjal (Solanum melongena L.) for growth, yield and fruit quality”.
