Variables related to foliar damage, leaf morphology, spectral reflectance, chlorophyll fluorescence and chlorophyll content were measured from leaves sampled from mature eucalypts exhibiting symptoms of crown dieback associated with bell miner colonisation located in Olney State Forest, near Wyong, New South Wales. Insect-damaged mature leaves and healthy young expanding leaves of some species ...

Pomegranate (Punica granatum L.) peel and sumac (Rhus coriaria L.) fruit and leaf extracts were chemically characterized and their ability to inhibit table grape (cv. Italia) rots caused by Botrytis cinerea was evaluated on artificially inoculated berries. Different extraction methods were applied and extracts were characterized through Ultra Fast High Performance Liquid Chromatography coupled ...

the mineral contents of centaura leave and seeds were determined by inductively coupled plasma-atomic emission spectroscopy (icp-aes). macro element concentrations (p, k, ca, mg and s) of samples were found at high levels. k was established at high level in both leave and seed samples of centaurea. while k contents of leaves changes between 7254.10 mg/kg (centaurea lycaonica) and 26396.36 mg/kg...

Bioactive materials of natural origin have great demand in industry and medicine due to their versatility useful properties. The main purpose this work is prepare biocomposites for the dual modified silk fibroin (Bombyx mori L.), which protects against destructive effects bioactive, antioxidant ultraviolet rays. For purpose, an aqueous extract autumn leaves anthocyanin-rich smoke tree plant (Co...

In vitro grown cabbage (Brassica oleracea var. capitata) seedlings exposed to excess molybdenum (Mo) ions exhibited severely reduced plant growth at the cotyledonary stage. Adding 80 mM proline (Pro) to the Mo-treated medium could help 50% seedlings to overcome the toxicity and grow true leaves. Under excess Mo stress, seedlings accumulated blue/purple anthocyanin in their cotyledons and hypoco...

Abstract Background Ananas comosus var. bracteatus is a colorful plant used as cut flower or landscape ornamental. The unique foliage color of this includes both green and red leaves and, trait interest, deserves investigation. In order to explore the pigments behind section chimeric leaves, parts were sampled analyzed at phenotypic, cellular molecular levels in study. Results CIELAB results in...
