Leaves are essential in the propagation of roses by cuttings. However, about the underlying principles, there is no unequivocal opinion in the literature. We investigated the hypothesis that current photosynthesis would represent the dominating factor. To validate this hypothesis variations in photosynthesis were created by reducing leaf area, covering of leaves and by reducing CO2 air concentr...

Prunus ferganensis (Kost. & Riab) Kov. & Kost, is closely related to cultivated peach, P. persica (L.) Batsch, but is distinguished by very long, unbranched leaf veins which turn and run parallel to the leaf margin at the edge of the leaf. Also, the pits have longitudinal grooves. Otherwise the tree and fruit of this species (or sub-species) resemble those of our familiar commercial peach. P. f...

The increase of atmospheric CO2 due to global climate change or horticultural practices has direct and indirect effects on food crop quality. One question that needs to be asked, is whether CO2 enrichment affects the nutritional quality of Malaysian young ginger plants. Responses of total carbohydrate, fructose, glucose, sucrose, protein, soluble amino acids and antinutrients to either ambient ...

Background: To ascertain the effects of tropical leaf meals on semen production and semen quality. Objective: This study was conducted with the main objective of investigating the effect of neem leaf meal on physiological responses of rabbit bucks fed graded levels of neem leaf (Azadirachta indica A. Juss) meal. Materials and Methods: The varying levels of neem leaf meal (NLM) in the different ...

This experiment was conducted to evaluation the effects of different levels of untreated and treated green grape leaf with urea on performance, egg quality traits and blood parameters of laying hens. In this experiment 192 Hy-Line (w-36) laying hens, 35 to 46 wk of age were divided in to 4 treatments with 4 replicates (12 birds per replicate) in a completely randomized design experiment. The tr...

Pharmaceuticals contribute greatly to human and animal health. Given their specific biological targets, pharmaceuticals pose a significant environmental risk by affecting organisms and ecosystem processes, including leaf-litter decomposition. Although litter decomposition is a central process in forest streams, the consequences of exposure to pharmaceuticals remain poorly known. The present stu...

A cryptic fungal endophyte, Neotyphodium coenophialum, infects most tall fescue (Festuca arundinacea) pastures in the United States. Cattle, sheep, and horses that consume the endophyte-infected grass can suffer fescue toxicosis caused by toxic alkaloids in the infected plants. The effects of the endophyte on mammalian herbivores have been well documented, but less is known regarding the qualit...
