Water stress may reduce leaf net photosynthetic carbon assimilation (A N ) through both stomatal effects, which the internal CO 2 concentration (C i ), and nonstomatal result in reduced A at a given level of C However, gas exchange techniques used to calculate are susceptible important artifacts when applied water‐stressed leaves, making such estimates unreliable. As an alternative , chloroplast can be calculated from simultaneous measurements measurements, thylakoid electron flux...

Plant growth, yield, and fruit quality of two strawberries ( Fragaria × ananassa Duch.)—`Chandler' `Sweet Charlie'—grown under high tunnels (HTs) were compared with that field plants during 2002–03 2003–04 growing seasons. Plug planted in mid-October 2002 mid-September 2003 on raised beds covered black polyethylene mulch. Microclimate the HTs protected strawberry crowns from winter damage advanced production 5 weeks earlier than grown conditions. From December to February, average minimum...

Field studies were conducted on <i>Vitis vinifera</i> L. cvs. Cabernet franc and Merlot to evaluate the effects of basal leaf removal timing severity 3-isobutyl-2-methoxypyrazine (IBMP) concentration in grape berries. Treatments consisted removing either 50% or 100% leaves from fruiting zone at 10 days after anthesis, 40 60 anthesis. In second year study, a 15-day postveraison treatment was also included. both years significant reductions IBMP (range = 28 53%) observed before veraison...

In the present study, morphological traits, organic acids, sugars, total phenols, flavonoids, anthocyanins, anthocyanidins, antioxidant activity and color parameters such as lightness(L*), Chroma (c*) hue angle (h°) were investigated in 11 local introduced fig cultivars cultivated Moroccan climate. Since only limited information on that topic is available literature, this study was performed order to compare clones with some of varieties based their biochemical attributes. Results showed...

The main objective of this study was to evaluate the ability both antagonistic bacteria Bacillus amyloliquefaciens (SF14) and Alcaligenes faecalis (ACBC1) used in combination with salicylic acid (SA) effectively control brown rot disease caused by Monilinia fructigena. Four concentrations (0.5%, 2%, 3.5%, 5%) were tested under vitro vivo conditions. Furthermore, impact biological treatments on nectarine fruit parameters’ quality, particular, weight loss, titratable acidity, soluble solids...

In the present study, chromatic coordinates, phenolic acids, flavonoids and antioxidant capacity assessed by 1,1-diphenyl-2-picrylhydrazyl (DPPH), 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonate (ABTS) lipid peroxidation inhibition (LPIC) essays their relative IC50 were investigated in 25 fig cultivars growing Morocco. The aims of this study to determine (i) variation these compounds among light dark-colored cultivars, (ii) partitioning between fruit peel pulp (iii) display network...

Palm date seeds oil of eight varieties were investigated for physical, chemical, and phytochemical analysis, compared to used commercial oils. Significant differences observed among varieties. The content the ranged from 6.05 10.25%. Fatty acid analysis using GC-MS revealed that oleic acids dominant component (38.67–44.38%) followed by lauric (21.72–26.66%), myristic (11.26–13.04%); palmitic (9.65–11.38%); linoleic (6.25–8.24%); stearic (3.06–3.32%) while linolenic was found in traces....

With the progresses of oilseed industry, an important interest is currently being focused on exploiting novel and underutilized sources for vegetable oils. Being so far less studied part in fig fruits, seeds separated from four cultivars were assessed their oil content, fatty acids identification, total phenolics invitro antioxidant analysis. A one-way Anova yielded statistically significant differences all parameters, with exception pentadecylic, margaric arachidic besides saturated acids....

Numerous fungal plant pathogens can infect fresh fruits and vegetables during transit storage conditions. The resulting infections were mainly controlled by synthetic fungicides, but their application has many drawbacks associated with the threatened environment human health. Therefore, use of natural plants antimicrobial potential could be a promising alternative to overcome side effects fungicides. In this regard, study aimed at evaluating antifungal activity saffron petal extract (SPE)...

Solar drying is affordable, requiring low energy and an eco-friendly method. Thus, the present paper studies efficiency characteristics of indirect solar convective in fruits Arbutus unedo L. as well its effects on fruit phenolic compounds. The samples were dried at 60 °C, 70 80 °C. Phenolic compounds investigated using a Liquid Chromatography platform. Experimental results revealed that effective moisture diffusivity determined by Fick’s second law varied from 1.51 × 10−9 to 4.68 m2/s,...

Apple fruit is one of the worldwide most industrially valuable horticulture crops. However, vulnerable to post-harvest brown rot degradation caused by Monilinia laxa and fructigena, which a prominent pre-and disease tree fruit. Numerous non-chemical treatments have been investigated so far control these pathogens provide an alternative option synthetic fungicides that are commonly used may negative effects on human health environment. Therefore, this study aimed assess in vitro vivo efficacy...

Extreme subfreezing temperatures occurred in January 2009 throughout the grapegrowing regions east of Rocky Mountains. In Ohio, temperature lows ranged between −22 and −31°C, which were considered critical for grapevine productivity survival.
