Defoliation is a commonly used viticultural technique to balance the ratio between grapevine vegetation and fruit. Defoliation is conducted around the fruit zone to reduce the leaf photosynthetic area, and to increase sunlight exposure of grape bunches. Apical leaf removal is not commonly practiced, and therefore its influence on canopy structure and resultant wine aroma is not well-studied. Th...

In this study, gold nanoparticles (AuNPs) were synthesized following a bioreductive route using extract of Eriobotrya Japonica leaf. For the synthesis nanoparticles, firstly, leaves collected from Eastern Black Sea region (Akçaabat-TRABZON) in Turkey and dried. Secondly, 20 g dried sample was shaken 400 mL distilled water for 180 min. extracted laboratoary microwave device at 4 minutes, 600 W l...

Abstract Background Leaf color is an important ornamental trait of colored-leaf plants. The change leaf closely related to the synthesis and accumulation anthocyanins in leaves. Acer pseudosieboldianum a tree native Northeastern China, however, there was less knowledge about biosynthesis many steps pathway remain unknown date. Results Anthocyanins metabolite transcript profiling were conducted ...

in order to determination of partitioning n fertilizer by using of leaf color chart (lcc) and chlorophyll meter (spad) in rice an experiment was conducted as split plot under randomized complete block design with three replications during 2006 and 2007 at rice research institute of iran. main plots were contained cultivars in three levels (grh1, khazar and hashemi) and sub plots were contained ...
