Recently, there has been a resurgence in the adoption of lightweight cold-formed steel (CFS) profiles as structural elements low- to mid-rise modular construction. Typically, openings for doors and windows are ever-present front rear elevations where shear walls find their optimal position ensure lateral stability CFS structures. These architectural design features translate into reduced areas ...

Factors affecting survival and recruitment of 3531 individually mapped seedlings of Myristicaceae were examined over three years in a highly diverse neotropical rain forest, at spatial scales of 1-9 m and 25 ha. We found convincing evidence of a community compensatory trend (CCT) in seedling survival (i.e., more abundant species had higher seedling mortality at the 25-ha scale), which suggests ...

Seedling recruitment of Dalmatian toadflax, (Linaria genistifolia ssp. dalmatica (L.) Maire and Petitmengin (Scrophulariaceae)), was examined in a 2-year field study in Montana using overseeding and plant/insect exclusion methods, to determine whether it was more limited by seed availability or interspecific plant competition. Overseeding test plots with toadflax seed had no effect on seedling ...

Karlsson. A. 1996. Site vrevaration of abandoned fields and earlv establishment of naturallv and direct-seeded birch in Sweden. Studia Forestalia Suecica 199, 25 pp. ISSN 0039-3150, ~ S B N 91-576-5152-3. Field experiments were carried out at four sites in Sweden to investigate the possibility of establishing downy birch (Betula pubescens Ehrh.) and silver birch (Betula pendula Roth) on abandon...

Abstract: In this experiment, the response of canola cultivars to salnity stress in germination stage was evaluated using a factorial experiment with four replications in completely randomized design. Six canola cultivars (Fornex, Alice, Orient, Consoul, Okamer and Okapi) were subjected to four salinity levels (0, 40, 80 and 120 mMol NaCl) under room, greenhouse, field? Salinity reduced the...

This research was carried out in order to evolution effect of salt stress on seedling growth and antioxidant activity of two safflower cultivars KW13 and IL111 in Islamic Azad University, Shoushtar branch. Salt stress treatments were applied using salt solutions with EC values of 0 (control), 4,6, 8,10 and 12 ds/m. All experiments were carried out under a dual factorial (cultivar × salinity lev...

In plants encouraged by the proliferation of seed, seed to plant survival factor to maintain the role is very vital and important. In order to evaluate different size effect's on the quality seedling production during germination in wheat (Triticum aestivum L.), this experiment was conducted in 2011 at Laboratory Sciences, Islamic Azad University Shahr-e-Qods Branch by a completely randomized d...

oxalate soluble pectin (osp) is related to fruit firmness with respect to the chelation of calcium ions with carboxyl groups of adjacent polyuronide chains. this study was carried out to explore the effect of time of fruit harvest, foliar spray with cacl2 during growing season on osp, polygalacturonase activity (pga), fruit firmness and the effects on fruit shelf life, quality and internal ...

Abstract In order to evaluation of seed (pod) priming and seed size (pod) effects on growth and anti oxidant enzymes activity of sainfoin (onobrychis viciifolia Scop.) seedling in normal and drought condition, this experiment was carried in green house condition in 2010. Treatments (16) included: two masses (Borojen and Ghazvin), two seed sizes (large, >4.5 mm and small, 4.5>…>3.5 mm) and four ...

The mode of inheritance of seedling color and plant pubescence was studied in two crosses among three parents, which differed for these traits. The results have revealed that purple seedling color was dominant over green seedling color and pubescence was dominant over nonpubescence. These two traits segregated independently of each other may be used as morphological markers individually for dif...
