growth traits, yield and fruit quality in ‘synda’ tomato were compared with those in tomatoes grafted onto either ‘king kong’ rootstock or onto their own rootstocks, (trained as single or double stem), and at two fruit thinning levels, of: no thinning or thinned to five fruits per truss. the data related to crop growth rate (cgr), relative growth rate (rgr), net assimilation rate (nar), leaf ar...

Purpose of Review This review shows that a more or less constant rate of tip-to-base vessel widening across species, together with the assumption that wider vessels are more vulnerable to embolism, suggests how climate should limit maximum vegetation height; together, these two factors predict a maximummean vessel diameter permitted by temperature and water availability at a site and thus maxim...

Saltcedar (Tamarix pentandra Pall.) stem cuttings responded vegetatively to various photoperiods of 11-, 14-, 17-, and 8 + 1-hour duration. Total stem length, average stem length, cuticle thickness, and xylem vessel member outside diameter were significantly maximal under a 14-hour photoperiod and less under photoperiods above and below this level. Numbers of stems and roots produced were signi...

Introduction: Post and core has been considered for endodontically treated tooth, especially in cases with severe damage crowns. Recently fiber reinforced composite posts (FRC post) have been used in the treatment of endodontically treated teeth. Because the length and diameter of posts are effective in stress distribution, the purpose of this study is to evaluate the effect of length and diame...

in order to study the effects of planting pattern on yield and yield components in different cultivars of forage corn (zea mays l.), an experiment was conducted at saline conditions (ec=6.43 ds.m-1) of dasht-e-malhe, neyshabour during growing season of 2009-2010. nine treatments and two furrow planting and furrow bed planting as main plots and three cultivars (ksc 704, zp 644 and ns540) as sub ...

The research aimed to produce new genotypes by hybridization. It was conducted in the Ornamental Plants Research Center of Mahallat from 2016 to 2018. Four varieties of gladiolus including Amsterdam, White Prosperity, Advance Red and Rose Supreme were chosen for hybridization. The progenies were evaluated in a randomized complete block design with three replications. The highest heritability in...

Field investigations are important tools for confirmation of the effectiveness of the organic manures on crop yield. As different N sources, this work presents a comparative study of the effects of urea, cow dung and poultry manure on plant height, stem length and diameter, leaf length, breadth and number accompanied with the fresh weight of plant, stem, leaf coupling stem leaf ratio and gross ...
