Plants usually tolerate drought by producing organic solutes, which can either act as compatible osmolytes for maintaining turgor, or radical scavengers protecting cellular functions. However, these two properties of solutes are often indistinguishable during stress progression. This study looked at individualizing osmotic adjustment versus osmoprotection in plants, using cowpea the model species. Two cultivars were grown well-watered soil, conditions, followed rewatering through fruit...
Chitosan is an environmentally-friendly active molecule that has been explored for numerous agricultural uses. Its use in crop protection well-known, however, other properties, such as bioactivity, deserve attention. Moreover, the modes of actions chitosan remain to be elucidated. The present study assessed levels total phenolic compounds, antioxidant potential, and expression reactive oxygen species (ROS) scavenging genes berries (skins seeds), leaves, cluster stems, shoots upon application...
Almonds have recognized health benefits, which are largely attributed to their chemical composition, including fatty acids, phenolics, vitamin E, and sucrose. This study was carried with the aim of providing information on levels aforementioned bioactive compounds antioxidant activities in six understudied Portuguese cultivars (Amendoão, Bonita, Casanova, Molar, Pegarinhos–Moncorvo, Pegarinhos–Murça Refêgo), comparison two foreign (Ferragnès Glorieta). A cultivar effect observed for all...
Almond is one of the most commonly consumed nuts worldwide, with health benefits associated availability bioactive compounds and fatty acids. often eaten raw or after some processing steps. However, latter can positively negatively influence chemical sensorial attributes almonds. This work was carried out to assess effects two treatments, namely; roasting blanching on (i) contents compounds, (ii) acids (3) antioxidant activities (4), characteristics four neglected Portuguese almond cultivars...
ABSTRACT Increase in the atmospheric carbon dioxide concentration ([CO 2 ]) enhanced of carbohydrates rice grains, according to results a previous study. However, its impact on other quality traits is little known. To investigate effect CO levels (375 and 550 μmol/mol) quality, field experiment was conducted with open‐top chambers. Elevated [CO ] affected several nutritional parameters grain. Whereas α‐linolenic acid increased, that linoleic γ‐linolenic acids decreased. For example,...
Both qualitative and quantitative changes occur in the lipid composition of Vitis vinifera L. tissues, which may compromise defense response against Esca complex disease, a widespread damaging trunk disease. In this study, lipidomic analysis grapevine leaves is conducted to assess how membrane remodeling relates emergence progression foliar symptoms. total, 208 molecular species (including lipids, four hormones, some other compounds metabolism lipids) were detected. Lipid readily assigned...
Nitrogen (N) is the primary nutrient required for plant growth. During last few decades, there has been extensive use of synthetic N-containing fertilizers in agriculture, resulting increased environmental pollution. In this study, feasibility replacing N with biofertilizer maize cultivation was investigated. A liquid (digestate obtained from anaerobic digestion swine wastewater) and applied to large plots as a total (100%) or partial (50%) substitute fertilizer. Moreover, most efficient...
ABSTRACT Little is known regarding the impact of elevated carbon dioxide concentration ([CO 2 ]) on chemical composition rice grains. A field experiment was conducted with open‐top chambers ( Oryza sativa L. cv. Ariete) grown at two levels atmospheric CO (375 and 550 μmol/mol), their effects were monitored proximate carbohydrate contents Following exposure to [CO ], soluble dietary fiber increased by 136, 82, 77% in brown rice, white bran, respectively. Increases a lower magnitude (8%)...
Abstract Late blight caused by Phytophthora infestans is the most important disease of tomato in Cameroon. Three experiments are conducted to assess fungitoxicity methylene chloride/methanol leaf extracts seven plants on P. development. The (3%) evaluated for sporangial germination inhibition, latent and incubation periods, lesion size late severity plants. Inoculated leaflets incubated greenhouse at 21°C during day 18°C night, with a 12 h photoperiod 7 days. Sporangial significantly...
Composts are widely used in horticulture as organic amendments to improve the properties of soils. have also been reported enhance disease suppressive potential soils and, therefore, could be a strategy for managing plant diseases. The aim this study was test ability amended with four different agro-industrial waste-based composts (chestnut peels and shells, spent coffee grounds, grape marc, olive leaves) inhibit growth activity Botrytis cinerea several soilborne pathogens. First, capacity...
