In the present study, we calibrated and validated thermal models to predict DOY date at which grape maturity index, potential alcohol/total acidity (PA/TA), reaches 0.75 (MS0.75), 1.0 (MS1), 1.5 (MS1.5), 2.0 (MS2) for two grapevine Portuguese varieties, Touriga Nacional (TN) Encruzado (EN), growing in Dão wine region, Portugal. Daily rates of forcing calculated with Sigmoid (SM) function Degree...

An experiment was conducted at the Fruit Research Farm of Punjab Agricultural University, Ludhiana, during 2019–20 to study impact mineral nutrients on fruit drop, powdery mildew and quality attributes ber (Ziziphus mauritiana Lam.) cv. Umran. A 15 year’s old plants were sprayed with like calcium nitrate @0.25 0.50%; potassium sulphate boric acid @0.40 0.60% liquid sulphur 0.50% along control (...

Orang drink is the most common flavoured consumed in Iraq and it can be found markets of all sizes provinces making them subjected to a wide range storage temperature time. In this work, effect time was studied on three different local brands Orange with Low-to-No nectar content; were packed Laminated Aseptic Cartons (LAC). Samples stored fixed controlled environment ranging between 10 ?C-50 ?C...

Phosphorus (P) is one of the most limiting nutrients for growth and development crops, important soil fertility managements, since it affects quality fruits. With hypothesis that different levels irrigation phosphorus fertilization interfere in physical physicochemical properties tomatoes, objective this experiment was to verify analyze behavior fruits’ responses. The conducted a greenhouse at ...

The aim of this study was to evaluate and compare potential different optical spectroscopic techniques for quality assessment apple juices. calibration partial least squares (PLS) regression models were developed optimized determination parameters juice non-destructively from the NIR spectra fruit or directly UV-VIS-NIR external validation performed using test sample set. Calibration based on c...

The current study in tomato (Solanum lycopersicum L.) was conducted at PAU, Ludhiana with the objective of developing hybrids possessing combined resistance to late blight and leaf curl virus diseases along desirable horticultural characteristics. experimental material which included 32 F1 (developed by line ? tester method), 12 parental lines (8 4 testers; including susceptible check Punjab Ch...

Palmyrah neera (inflorescence sap) is susceptible to natural fermentation at ambient temperature within a few hours of extraction due enzymatic and microbial activity. Once fermented, becomes toddy which unsuitable as health drink or value-added product. Therefore, study was carried out investigate the influence different packing materials storage conditions on shelf life keep quality palmyrah ...

Abstract During postharvest life, strawberry fruit as a perishable commodity exhibiting short shelf life suffers from fungal decay that severely limits its marketability and nutritional value. Herein, we investigated the mechanisms activated by exogenous phytosulfokine ? (PSK?) application at 150 nM to delay senescence relieve in during storage 4 °C for 18 days. Our results showed higher extrac...

Changes in physicochemical traits, peel colour, and juice attributes of four blood orange cultivars (‘Moro’, ‘Tarocco’, ‘Sanguinello’, ‘Sanguine’) were evaluated during 180 days at 2 5 °C plus 20 for shelf life. ‘Tarocco’ had the lowest weight firmness losses both temperatures storage. Titratable acidity (TA) was higher than °C, with ‘Sanguinello’ showing highest TA, respectively. Juice content...
