carbon dioxide (co2) concentration of the global atmosphere has increased during the last decades. increasing global atmospheric co2 concentrations are expected to influence crop production. in order to evolution of co2 concentration effects on morphophysiologycal traits in tagets, ageratum and gauilardia, a factorial experiment based on completely randomized design with 3 replications and 12 t...
In this research, to evaluate the effect of superabsorbent polymer and drought stress on the number and leaf area of Lettuce, experimental research was conducted in a completely randomized design factorial with two treatments of irrigation regime at three levels (60, 80 and 100 percent of crop water requirement) and four superabsorbent hydrogel application (0, 4, 6 and 8 g per kg of soil) in t...

Land plants lose vast quantities of water to the atmosphere during photosynthetic gas exchange. In angiosperms, a complex network of veins irrigates the leaf, and it is widely held that the density and placement of these veins determines maximum leaf hydraulic capacity and thus maximum photosynthetic rate. This theory is largely based on interspecific comparisons and has never been tested using...
This study was conducted to evaluate the effects of paclobatrazol and cycocel on some quantitative and qualitative traits of zinnia. Seedlings were transplanted on Horticulture Department Farm , College of Agriculture, Isfahan University of Technology. The experiment was carried out in the framework of randomized complete block with 3 replications. Triats which were studied included plant heigh...
for study the effect of arbuscularmycorrhiza fungi a factorial experiment in a randomized complete block design with four replications was carried out in the summer of 1389 at the agricultural research station in city of zahak. the experiment included two factors; the first factor was inoculated glomus mossea mycorrhiza and no-inoculated one. the second factor was in four varieties of corn: s.c...
This study was accomplished with the aim of investigating the effects of tree decline and slope aspect on leaf morphological traits and determining the indicator morphological traits that indicate the leaf diversity of Persian oak trees in relation to habitat conditions and environmental stresses in Mellah Siah forests of Ilam. Two forest habitats were selected on the northern and southern slop...
