light intensity is considered a limiting factor in greenhouse rose production. the main aim of this experiment was to evaluate the effect of shading treatments (0, 25, 50, and 65% shading) on quality and chlorophyll content of cut rose (rosa hybrida cv. avalanche), under greenhouse conditions. the experiment was planned in randomized completely block design with four replications. all shoots we...

During maize development and reproduction, shading stress is an important abiotic factor influencing grain yield. To elucidate the genetic basis of shading stress in maize, an F(2:3) population derived from two inbred lines, Zhong72 and 502, was used to evaluate the performance of six traits under shading treatment and full-light treatment at two locations. The results showed that shading treat...

throughout the present study some vegetative and reproductive characteristics of rosa damascene fewer than three different irrigation regimes (100, 70 and 40% of potential evapotranspiration) through an application of surface vs subsurface drip irrigation systems were investigated. some morphological characteristics investigated, included the number of branches per plant, shading diameter, plan...

This paper aimed to evaluate the initial growth of "mutambo" seedlings in different conditions of light intensity and treatments with gibberellic acid (GA). The seedlings were kept under full sun and 50% of shading. Sixty days after the emergence, seedlings were sprayed with: 1) 100 mg L(-1) GA(3); 2) 200 mg L(-1) GA(3); 3) control. At the end of the appraisals, seedlings height under 50% of sh...

The role of competition in tree communities is increasingly well understood, while little is known about the patterns and mechanisms of the interplay between above- and belowground competition in tree communities. This knowledge, however, is crucial for a better understanding of community dynamics and developing adaptive near-natural management strategies. We assessed neighbourhood interactions...

effects of different mulches and saran shading on yield and quality of tomato (lycopersicon esculentum cv. early urbana vf) were studied at ilam university, ilam, iran in 2009. the research work was carried out using a 4×4 split plot experimental arrangment through a completely randomized block design (crbd) of three replications, where shading levels of 0%: no shading; 40%: white; 55%: double-...

The individual components of the slope-parallel surface radiation balance were measured in and around Arizona’s Meteor Crater to investigate the effects of topography on the radiation balance. The crater basin has a diameter of 1.2 km and a depth of 170 m. The observations cover the crater floor, the crater rim, four sites on the inner sidewalls on an east–west transect, and two sites outside t...
