The concentration of salts in the vesiculated hairs of Atriplex halimus L. was measured and was remarkably higher than that of the leaf sap and xylem exudate. In spite of their unusually high salt content, these hairs when immersed seemed unable to absorb water, in apparent contradiction to the previously held hypothesis that vesiculated hairs make it possible for such plants to absorb water fr...

Blackcurrant leaves are an essential source of phenolic compounds and this study investigated their variation relative to leaf positions and harvest date. The phenolic content varied between harvest dates, although leaf position on the shoot and interactions also played an important role. The contents of quercetin-malonyl-glucoside, kaempferol-malonyl-glucoside isomer and kaempferol-malonyl-glu...

As sugar beet source leaves lowered the CO(2) concentration to compensation point in a closed atmosphere, leaf thickness and relative water content decreased. Leaf water potential declined rapidly from -0.5 to -1.4 megapascals. At 340 microliters CO(2) per liter, water potential and sucrose, glucose, and fructose contents were steady in photosynthesizing source leaves. Within 90 minutes after l...

this study was undertaken to identify morphological changes in young seedlings of 5 iranian almond species (prunus dulcis, p. eburnea, p. eleagnifolia, p. haussknechti, and p. scoparia) under polyethylene glycol-induced drought stress. drought stress caused a significant reduction in plant growth parameters such as fresh and dry weights of plant organs, leaf number, total leaf area, and leaf re...

BACKGROUND AND AIMS Epidermal phenolic compounds (mainly flavonoids) constitute a vital screen that protects the leaf from damage by natural ultraviolet (UV) radiation. The effectiveness of epidermal UV-screening depends on leaf anatomy, the content of UV-screening compounds and their spatial uniformity over the leaf area. To investigate in vivo the spatial pattern of the epidermal UV-screen du...

The study was conducted on physiology and biochemical performance and correlation for yield and its quality characters of 18 genotypes of Glory lily (Gloriosa superba). Experiment was laid out in a randomized block design with three replications at the Medicinal Plants Unit, Botanical Garden, Tamil Nadu Agricultural University, Coimbatore. Genotypes GS 15, GS 06, GS 18, GS 03 and GS 02 were com...

the influence of moisture content of mulberry leaf on the growth, development and moisture build up in the body of silkworm was studied by feeding with different maturity leaves to late age of silkworm larvae. significantly higher larval moisture (79.78%), larval weight (65.65 g), pupal moisture (73.81%) was recorded in top tender leaf (high moisture) fed batches and least was recorded in the c...

Changes in dry matter and water-soluble carbohydrate components, especially fructan, were examined in the basal 25 mm of expanding leaf blades of tall fescue (Festuca arundinacea Schreb.) to assess their roles in plant response to water deficit. Water was withheld from vegetative plants grown in soil in controlled-environment chambers. As stress progressed, leaf elongation rate decreased sooner...
