let h be a separable hilbert space and let b be the set of bessel sequences in h. by using several interesting results in operator theory we study some topological properties of frames and riesz bases by constructing a banach space structure on b. the convergence of a sequence of elements in b is de_ned and we determine whether important properties of the sequence is preserved under the con...
to evaluate the effect of slow release fertilizer and humic acid on quality of new guinea impatiens (impatiens hawkeri), an experiment established in complete random design with 15 treatments and three replications. treatments were slow release fertilizer (12-11-18-2.7mgo-8s) in five levels (0, 1.5, 3, 4.5 and 6 kg/m3) and humic acid in three levels (0, 2 and 4 kg/m3) that mixed with medium cul...
BACKGROUND AND AIMS It is well known that plant aerial development is affected by light intensity in terms of the date of flowering, the length of stems and petioles, and the final individual leaf area. The aim of the work presented here was to analyse how shade-induced changes in leaf development occur on a dynamic basis from the whole rosette level to that of the cells. METHODS Care was tak...
topping stage of tobacco is a key time for development of agriculture measures to promote the quality of leaves. in order to investigating influence of topping timing and suckericide content on tobacco leaf, a factorial experiment on the basis of rcb design with 3 replications was conducted in 2011 at the tobacco research farm of isfahan. treatments were including topping time (t1: topping at e...
to evaluate growth characteristics and adaptation of new asian pear cultivars (pyrus serotina rehd.) in iran, some growth characteristics and physiological factors of nine asian pear cultivars named ‘ks’6, ‘ks’7, ‘ks’8, ‘ks’9, ‘ks’10, ‘ks’11, ‘ks’12, ‘ks’13, ‘ks’14 and one european, present commercial cultivar ‘shahmiveh’ of iran (control) were evaluated under the climatic conditions of tehran ...
Mulberry (Morus spp.) is a perennial tree cultivated for its foliage to rear the domesticated silkworm, Bombyx mori L. Mulberry has improved through conventional breeding in general aims to improve the quantity and quality of leaf yield, which have direct bearing on silk productivity. Leaf senescence is one of the major constraints, which restricts the quantity of quality leaf availability for ...
The appropriate planting pattern of safflower in summer planting might be different from the planting pattern suitable for spring planting, and this has not been determined under Isfahan environmental conditions. A field experiment was conducted in the summer of 2000 at the Agricultural Research Station, Isfahan University of Technology, using a randomized complete block design with a split plo...

Studies were conducted to quantify leaf area damage to ‘Tahiti’ lime by citrus leafminer (CLM) (PhyllocnistLF citrella Stainton) and to relate leaf damage to larval density and the length of time mining per leaf. Visual estimates of leaf damage were similar among five evaluators and were positively correlated with image analysis determinations. The number of CLM larvae per leaf and the number o...
