India is the largest producer of acid lime in the world and they are used as fresh fruit or for the preparation of pickles and beverages. They are rich in vitamin C, minerals and salts. The seasonality of production leads to market glut which results in poor returns to the farmers. Hence, an experiment was conducted to manipulate and regulate flowering by using various plant growth regulators viz., GA­3 and cycocel, chemicals viz., KNO3 and salicylic acid at 11 different treatment combinations. The experiment was conducted in randomized block design (RBD) and each treatment was replicated thrice. The age of the trees was seven years and the variety used was PKM1. The experiment conducted in four consecutive years. The experimental results showed that there were significant differences among the treatments. Acid lime trees sprayed with GA3 50 ppm in June + cycocel 1000 ppm in September + KNO3 2% in October recorded the highest number of fruits tree-1 (1003), weight of fruits (48.60 g) and average fruit yield (28.96 kg tree-1). The same treatment registered the highest values for juice content (32.13 %), TSS (7.29o Brix) and ascorbic acid content (32.56 mg / 100ml).

To increase the strawberry production especially during offseason with the application of plant bio-regulators, the present study was conducted under subtropical mid-hill conditions of Arunachal Pradesh, India during spring-summer months of 2015-16. Effect of springtime foliar application of different plant bio-regulators viz., NAA, GA3, and BA on plant growth, yield and quality attributes of strawberry cv. Chandler with the advantage of increasing strawberry production during the off-season was accessed during the current study. The experiment was laid out in a randomized block design with ten treatment combinations (NAA, GA3, and BA at 50, 100, and 150 ppm each) replicated thrice considering water spray as control. The plant bio-regulators were sprayed at 25 days after transplanting and at the bud initiation stage. Results of the experiment revealed that the plants treated with GA3 150 ppm significantly influenced the plant height and number of leaves per plant at 30, 45, 60 and 75 days after transplanting. The minimum number of days taken to open the first flower (62.11 days) and the maximum number of runners per plant (9.17) were also recorded in the plants treated with GA3 150 ppm. While, GA3 50 ppm treated plants yielded fruits with maximum berry length (3.69 cm), berry width (2.74 cm), average berry weight (13.99 g), number of berries per plant (21.11) and yield per plant (209.11 g). Concerning the quality parameters of fruits, plants treated with NAA 100 ppm exhibited maximum TSS (9.00° B), total sugar (7.23 %), and ascorbic acid content (77.82 mg/100 g) whereas, GA3 100 ppm treatment significantly increased the contents of anthocyanin (122.18 mg/100 g), total phenols (69.42 mg/100 g) and β-carotene (3.96 µg/100 g).

The tomato fruit is rich in antioxidant compounds and has great nutritional and economic importance, annually promoting research on the nutritional and productive characteristics. The present study aimed to evaluate whether foliar application of commercial products based on growth regulators [auxin, cytokinin and gibberellin (Ax+CK+GA)], micronutrients [cobalt and molybdenum (Mi)] and mixtures of macro and micronutrients [nitrogen, boron, copper, molybdenum and zinc (Ma+Mi)], isolated and in combination, increase productivity and improve the post-harvest quality of tomato fruits (Predador F1). The experiment design used randomized blocks, with seven treatments and four repetitions, which were (T1) control; (T2) Ax+CK+GA; (T3) Ma+Mi; (T4) Mi; (T5) Ax+CK+GA + (Ma+Mi); (T6) Ax+CK+GA + Mi; and (T7) Ax+CK+GA + Mi + (Ma+Mi). The variables production, precocity, soluble solids content (SS), titratable acidity (TA), ratio (SS/TA), pH, total soluble sugars, ascorbic acid and weight loss were evaluated. The Ax+CK+GA application, isolated or in combination with Ma+Mi, promoted the precocity, and the use of isolated Ax+CK+GA and Mi improved the tomato plant productivity. The growth regulators, macro and micronutrients, isolated or in combination, increased the ascorbic acid content in the fruits.

Aim: To evaluate the efficacy of foliar application of Ascophyllum nodosum extract, homobrassinolide, and triacontanol for improving fruit retention, yield, and quality in mango. Methodology: The experiment was laid out in a randomized block design with 10 treatments, comprising Ascophyllum nodosum extract (1000, 3000, and 5000 ppm), homobrassinolide (0.1, 0.3, and 0.5 ppm), triacontanol (1, 3, and 5 ppm), and water as control. Treatments were foliar sprayed at panicle initiation, pea, and marble stages of fruit growth. Observations were recorded on flowering, fruiting, yield, and fruit quality parameters. Results: All the treatments of Ascophyllum nodosum extract and triacontanol exhibited significant improvement in fruit retention, fruit weight, yield, and fruit quality parameters over control. However, 3000 and 5000 ppm Ascophyllum nodosum extract treatments outperformed all the treatments of triacontanol. Plants sprayed with 5000 ppm Ascophyllum nodosum extract recorded the maximum value for fruit retention (48.15, 36.74, 29.48, and 25.76% at 3, 6, 9, and 12 weeks after pea stage, respectively), number of fruits (133.25 per tree), fruit weight (188.84 g per fruit), and yield (25.16 kg per tree), whereas the lowest values were recorded under control. With respect to fruit quality, 3000 ppm ANE produced the fruits with the highest TSS (19.62 °B), whereas the highest TSS/acid ratio was recorded with 5000 ppm ANE (62.29) treatment. Interpretation: In mango, foliar application of Ascophyllum nodosum extract (3000-5000 ppm) thrice at panicle initiation, pea, and marble stages of fruit growth is effective for reducing fruit drop and enhancing quantum and quality of produce.

ABSTRACT The family farming from the Borborema Territory-PB, Brazil, produces sweet oranges that supply the regional market. In this context, it is necessary to define standards of identity and quality, as well as to quantify the bioactive compounds in the fruit, in view of adding value and creating more competitive markets. This work sought to evaluate the quality, bioactive compounds and total antioxidant activity (TAA) of oranges from family farming. A 3x3 factorial completely randomized design was used, with three cultivars (Baía, Comum, Mimo-do-Céu) and three maturity stages (predominantly green, green/yellow, yellow), with 60 replications of 1 fruit for the physical evaluations, and 4 of 15 fruit for the others. The whole fruits were evaluated by color index, length, diameter, fresh weight and firmness. The juice was assessed for yield, pH, soluble solids (SS), titratable acidity (TA), SS/AT ratio, and ascorbic acid. Total extractable polyphenols (TEP) and ABTS•+ and DPPH• total antioxidant activity (TAA) were measured in the juice and albedo. The 'Baía' and 'Mimo-do-Céu' oranges presented quality parameters aligned with the CEAGESP standards. On average, the ascorbic acid content was higher than 45 mg 100 g-1, with ‘Mimo-do-Céu’ presenting the highest content (50.26 mg 100 g-1). During maturation, the firmness decreased, and the SS, TEP and TAA of the juice and the albedo increased. In general, the TEP content was about eight-fold higher in the albedo than juice, corresponding to the much higher TAA in this portion, thereby highlighting its higher functional potential, especially for ‘Baía’ orange.

ABSTRACT Aiming at the generation of new guava varieties with superior attributes, we conducted this study adopting the REML/BLUP procedure at individual level. Seventeen segregating guava families were evaluated in a randomized-block design with two replicates and 12 plants per plot. Families were obtained after controlled biparental pollination. The studied individuals showed high genotypic variance for fruit weight (FW), total yield (YLD), and ascorbic acid content (AAC). The heritability coefficients of the mean of progenies led to high progeny-selection accuracy for pulp yield (PY), soluble solids content (SSC), in addition to FW, YLD, and AAC; moderate accuracy for fruit acidity (FA) and SSC/FA ratio; and low accuracy for mesocarp thickness (MT) and pH. Selection among families (h2mp) indicated the highest values for FW, PY, YLD, SSC, and AAC, revealing that, for the present study, this practice would be effective, since these traits allowed for the highest selection accuracy values among families. As for the ranking of individuals, families originating from crosses UENF 1835 × UENF 1834, UENF 1831 × UENF 1832, and UENF 1831 × UENF 3739 stood out, occupying the first positions for most traits.
