“…Application of BRs in the combination with CPPU and GA enhance the leaf number, leaf area and the dry weight of the seedless grape's variety Tas-A-Ganesh [30]. The combination of BRs and NAA treatment improved pineapple fruit size, shape, and quality in the 'Pattawia' variety [31] Mostafa et al [32] was showed in their study that the sugar apple Annona squamosa L. treated with brassinosteroids in the combination with the hand pollination enhance fruit quality and fruit set. In terms of plant height, number of leaves, number of branches, leaf area, number of buds, day to first flowering, number of flowers per plant, day to first fruit set, number of fruits per plant, Polar and Radial diameter (cm), fruit weight (g), and fruit yield (q/ha), as well as quality parameters such as T.S.S, acidity, Ascorbic acid, and shelf life of Cape gooseberry, brassinosteroids was found to be the best treatment [33].…”

Plant growth regulators are extremely important natural hormones which control the growth and the physiological factors within the plant. They are naturally occurring as well as synthetic. PGRs like Auxins, ethylene, cytokinins and gibberellins are the growth inhibitors and growth retardants. The foliar application of plant growth regulators helped in increasing the quality of the fruit crops. Auxin is required for fruit retention in sweet cherry, litchi, grapevine, snake fruit and tomato. Most commonly used auxins are IBA, NAA, IAA, 2,4D etc. IBA at the concentration of 4000 ppm is the best plant growth regulator for rooting in cuttings. Gibberellins (GA) are diterpene plant hormones that influence various aspects of growth and development through complex biosynthetic processes. Application of GA with combination of Zinc and pruning showed better performance in fruit weight, ascorbic acid, and reduction in pre-harvest fruit drop. Repeated applications of brassinosteroid have a long-lasting effect on strawberry cv. Winter Dawn physiological growth. Triacontanol (TRIA), natural plant growth hormone in fruit crops. It regulates a variety of physiological processes in plants. Salicylic acid (SA) is a plant hormone best recognized for modulating host responses in response to pathogen infection.SA treatments boosted crop productivity and fruit quality criteria such as firmness, aril color, and individual sugar and organic acid concentrations at harvest. It is revealed by many studies that the application of biofertilizer play an essential role for increasing the sustainability of the soil and also enhance the organic matter content, aeration, fertility, availability of micro and macronutrients with in the soil which are the essential things for the better survival of the plant and results into the good quality and higher yield from the plant. The present review encompasses the use and the effect of different PGR’s and biofertilizer on the fruit crops.

“…4-chlorophenoxy acetic acid (synthetic auxin) is a plant growth regulator plays an important role in alleviation of stress, increasing fruit set and fruit size (Picken and Grimmett, 1986;Karakurt, 2000;Ramin, 2003;Sasaki et al, 2005). Brassinosteroids are a new class of plant growth regulators that regulate many physiological properties in plant processes including stimulating elongation, decreasing fruit drop, increasing fruit set, enhancing fruit quality and alleviating biotic and abiotic stresses (Bartwal et al, 2013;Wang et al, 2013;Symons et al, 2006;Chumpookam et al, 2017;Baghel et al, 2019). Thus, the objective of this experiment was to study the influence of 4chlorophenoxyacetic acid (4-CPA) and brassinosteroids on fruit set, yield and quality of "Keitt" mango fruits.…”

The present experiment was conducted on six-years-old "Keitt" mango trees at El-Bostan region, El-Behira governorate, Egypt to study the effect of 4-chlorophenoxyacetic acid (4-CPA) and brassinosteriods (BR) on fruit set, yield and quality of "Keitt" mangos. The following seven treatments were used, control, brassinoloide at 1 mg/L, brassinoloide at 2 mg/L, 4-chlorophenoxyacetic acid at 10 mg/L, 4-chlorophenoxyacetic acid at 20 mg/L, brassinoloide at 1 mg/L + 4-chlorophenoxyacetic acid at 10 mg/L and brassinoloide at 2 mg/L + 4chlorophenoxyacetic acid at 20 mg/L. The treatments were applied twice at full bloom and after fruit set with ten days. The results showed that pre-harvest application of 2 mg/L brassinoloide increased fruit set, fruit retention, yield, average fruit weight, average fruit size and ascorbic acid. Pre-harvest applications of 4-chlorophenoxyacetic acid either at 10 mg/L or 20 mg/L increased fruit set, retention, yield, fruit weight, size, fruit firmness and ascorbic acid. The formulation containing 4-chlorophenoxyacetic acid plus brassinoloide either at low concentration or high concentration enhanced fruit set, yield, firmness, fruit physical and chemical quality of "Keitt" mangos fruit.

“…It determines the acceptance by the consumer and they are willing to pay a higher price for good quality fruits [10,11]. It is now well established that the pineapple plant reacts to the application of PGRs such as naphthalene acetic acid (NAA), gibberellic acid (GA), and brassinosteroid (BR) in several ways and improves fruit growth along with its quality [12][13][14][15][16][17]. In this context, the primary purpose of this research work was to investigate the influence of PGRs in enhancing the fruit growth and quality attributes of pineapple.…”

Aims: A trial was conducted to investigate the influence of plant growth regulators on the growth and quality attributes of pineapple fruits. Study Design: The experiment was arranged in a randomized completed block design (RBCD) with three replications using 25 plants per replication. Place and Duration of Study: The experiment was carried out between 2020 and 2021 at the Central Horticultural Experiment Station, Aignia, Bhubaneswar, India. Methodology: The application of PGRs i.e. naphthalene acetic acid (NAA), gibberellic acid (GA), and brassinosteroid (BR) was done at the flower initiation stage. Only water application is done in case of control. Fruits were harvested at the ripe stage and an analysis of different growth and quality parameters were done. Results: The application of naphthalene acetic acid (NAA), and gibberellic acid (GA) significantly improved the yield and quality attributes of pineapple. Application of NAA 200 mgL-1 (T3) was found to be the most effective in enhancing absolute growth rate (2.65 g day-1), fruit weight (1.58 kg), and fruit/crown ratio (6.38). It was also evident that the application of NAA 200 mgL-1 improved fruit quality in terms of soluble solid contents (17.67 oBrix), soluble solid contents to acid ratio (19.49), reducing sugar (3.54%), and total sugar content (12.38%). Higher pulp content (73.89%), pulp-to-peel ratio (3.49), and juice content (54.50%) were also observed with NAA 200 mgL-1. Conclusion: NAA 200 mgL-1 significantly improved fruit growth i.e. fruit weight, fruit-to-crown ratio, and absolute growth rate. It also enhanced the quality attributes of pineapple fruits i.e. pulp content, pulp-to-peel ratio, juice content, pH, soluble solid contents, SSC to acid ratio, reducing sugar, and total sugar content.
