“…Since GA stimulates the elongation of cells and thus is intimately involved in vegetative growth of plants. These results are in agreement with the findings of Kumar et al [7] who reported that cultar @ 1500 ppm was most effective in reducing the plant height, extension growth and shoot internode length in peach trees under high density planting system. Similar results have been confirmed by Basak [8] in Jonagold apple trees and Miller [9] in Red Chief Delicious apple trees.…”

The present investigation entitled “Regulation of growth, fruiting and biochemical characteristics in Fuji Zehn Aztec and Red Braeburn apple cultivars through application of growth retardants under high density planting system” was conducted in the Experimental Block of the Division of Fruit Science at Sher-e-Kashmir University of Agricultural Sciences & Technology of Kashmir, Shalimar campus, Srinagar (J&K) during the years 2020 and 2021. Four-year-old apple cultivars Fuji Zehn Aztec and Red Braeburn on M9-T337 planted at a distance of 3×1 meter of uniform age, vigor and girth were used for the study. The experiment comprising of seven treatments viz., control, prohexadione-calcium @125 ppm, prohexadione-calcium @250 ppm, prohexadione-calcium @500 ppm, paclobutrazol @200 ppm, paclobutrazol @400 and paclobutrazol@600 ppm was laid out in randomized complete design with three replications. The chemicals were sprayed one week after petal fall, three weeks after 1st spray and three weeks after 2nd spray. Paclobutrazol@600 ppm resulted in maximum reduction in vegetative growth parameters in both the apple cultivars under study.

“…Because, a threshold concentration is required for growth inhibition (Birecka, 1967) [2] , with reports of low concentrations actually promoting stem elongation (Tolbert, 1961;Halevy and Wittwer, 1965) [21,6] . Furthermore, fruit number and yield increased by application of cycocel @ 1500 ppm on peach but had no significant effect on fruit weight, TSS and acidity (Kumar et al 2005) [9] . According to Kulkarni et al (2018) [8] three different concentrations (1000, 1500, 2000 mg/l) of CCC at three different stages (5, 7, 12 leaf stage) were superior in respect to reducing total shoot length, internodal distance, leaf area, cane weight and increased cane thickness, petiole diameter and well developed cluster primordial (Percent fruitfulness).…”

Chemicals that slow cell division and cell elongation in shoot tissues and regulate plant height physiologically without formative effects. So far only chemical growth retardants are available in market which have residue problem. So, to overcome residue issue Vasumitra Life Energies Pvt. Ltd has developed a formulation of herbal extract having role in induction of fruitfulness as well as retardation of unwanted shoot growth. The extract was applied to vineyard at Pandharpur, during the year 2018-19 at different concentrations keeping Chlormequat Chloride (CCC) as check and one control treatment replicated five times at 5, 7 and 15 leaf stages after foundation pruning as well as 3 leaf stage after fruit pruning. The results revealed that significantly reduced shoot length, internodal length and increases the cane thickness of grape vine. The SPAD values, number of bunches per vine, weight of bunch were found significantly higher in treatments with herbal extract as compared to CCC and control. Fitochek @ 2 ml/lit showed highest fruitfulness percentage 65%, and yield 16.46 t/acre. It had no significant influence on berry length, berry diameter, TSS and acidity. Fitochek and control had no residues at harvest while CCC have residue above EU MRLs. Furthermore, no phytotoxic effects on grape vine were observed in any of treatments under investigations. From the above result and literature surveyed this is first report to demonstrate this novel organic compound (Fitochek) can be used effectively @ 2 ml/lit at different stages (After Foundation and fruit pruning) to retard unwanted shoot growth as well as overcome the residue problem.
