dc.description.abstractThe investigation entitled “Effect of chlormequat chloride (CCC) on growth, yield and fruit quality of grapes under protected conditions” was carried out at Fruit Research Farm, Department of Fruit Science, Punjab Agricultural University, Ludhiana. The experiment was conducted on grape cvs. Flame Seedless, Perlette and Punjab Purple grown in protected structure and open field conditions. Application of chlormequat chloride (250, 500, 750 and 1000 ppm) was done when the vines reached 5-leaf stage after sprouting. Results revealed that application of chlormequat chloride reduced the vegetative growth in terms of cane length and internodal length with maximum reduction recorded in the vines sprayed with highest dose of chlormequat chloride. Under the protected field conditions the increase in cane length at various intervals was more as compared to open field. At the end of observation period (69 days), the lowest cane length (110.0cm) in Flame Seedless was recorded with chlormequat chloride@ 1000 ppm while it was 204.4 cm in case of control. Similarly, the foliar application of CCC @ 1000ppm followed by CCC @ 750 ppm was found to be the most effective in reducing leaf size and trunk girth. Also, chlormequat chloride decreased the content of IAA and GA3 on each date of sampling relative to untreated buds. Application of CCC @ 1000ppm and 750 ppm was adjudged as the best treatment for improving the bunch quality in terms of TSS, total sugars and anthocyanin content in the berries. In Punjab Purple under protected field conditions, the maximum TSS content was found in 750 ppm chlormequat chloride (20.34%) which was at par with 1000 ppm chlormequat chloride (19.85%). Among the various treatments, foliar application of CCC @ 1000 ppm significantly improved the average yield and quality of grape clusters viz. bunch weight, size, berry weight and size and TSS: acid ratio. Under protected conditions, yield of Flame Seedless (9.48 kg/vine) and Perlette (7.42 kg/vine) was highest in CCC @ 1000 ppm as compared to control (7.56 and 5.22 kg/ vine respectively).en_US
