TL;DR: In this paper , the effect of different maturity levels on berry composition and postharvest quality of table grapes was investigated and three grape cultivars (Sultanina-C, ‘Flame Seedless’ and ‘NARC Black’) were harvested at early (M1) mid (M2) and late (M3) maturity stages.

TL;DR: In this article , the authors investigated different LED light color (Blue, Red and White) and glycine concentrations (0, 40 and 80 mg L−1) on photosynthetic efficiency of black henbane (Hyoscyamus niger L.) plant in a completely randomized design (CRD).

TL;DR: In this paper , the authors used liquid chromatography-mass spectrometry (LCS) to annotate the secondary metabolites in Verbascum thapsus leaves and flowers.

TL;DR: Artemisinin and its derivatives are now used worldwide for treatment of malaria, largely in combinations with other antimalarial drugs known as ART combination therapies (ACTs) as mentioned in this paper .

TL;DR: In this paper , a total of 1,997 polymorphic SNP markers were successfully mapped onto 18 different linkage groups and six QTLs were identified based on the genetic map using the multiple QTL mapping (MQM) method.

TL;DR: In this paper , the authors investigated the cytotoxic, apoptotic, anti-invasive, oxidant, antioxidant, GST inhibitory activities of caffeic acid in colorectal cancer cells.

TL;DR: In this paper , a review of the many roles that calcium plays in plant growth has been presented, including the various processes via which Ca2+ has been studied to play a part throughout these stresses.

TL;DR: In this article , the effect of humic acid on the growth parameters and secondary metabolites of stevia (Stevia rebaudiana B.) under different soil moisture conditions, was done at the experimental filed of Western Tehran, Iran during the growing season 2018-2019.

TL;DR: In this article , the authors analyzed the independent allelopathy and the co-allelopathy of two Asteraceae invasive plants, Solidago canadensis L. sativa and Conyzacanadensis (L.) Cronq., on seed germination and seedling growth of the horticultural Asteraceae species Lactuca sativa L. under a gradient of salt stress.

TL;DR: In this paper , the main focus of this study, Teucrium multicaule is also renowned for being an important medicinal and aromatic plant in Turkiye, and all extracts were found to be quite rich in phytochemicals by LCHRMS.

TL;DR: In this article , the potentials of aerial tissues in comparison to rhizomatous tissues were analyzed to estimate polyphenols, flavonoids, and saponin (Borassoside E) as well as in-vitro antidiabetic and antioxidant potentials.

TL;DR: In this article , the authors provide a critical analysis of plant chemicals with mosquito larvicidal efficacy and their mode of action, which have been reported for the past 10 years, and a total of 180 compounds from 97 plant species have been recorded, including methyl palmitate, proanthocyanidins, 22-monacetonide, and 20-hydroxyecdysone.

TL;DR: In this paper , the role of exogenous application of moringa leaf extract (MLE) in ameliorating perturbations caused by salinity (200 mM) in some physiological, biochemical and anatomical parameters of two canola varieties i.e. Super (V1) and Punjab (V2).

TL;DR: In this article , Carotol and carotol derivatives are suggested as a potential treatment for neurodegenerative disease associated with neuroinflammation, which are key detrimental processes involved in the etiology of Alzheimer's disease (AD).

TL;DR: In this article , the effects of foliar application of amino acids biostimulants (Perfectose™, liquid) on yield and leaf quality of two lettuce cultivars, romaine and iceberg, under soilless conditions.
