in mulberry (morus sp.), grown for its foliage, which is the sole food for the silkworm (bombyx mori l.), evolving high yielding varieties is a long drawn and laborious process. one of the important selection parameter that has significant positive correlation with leaf yield is total shoot length [tsl] of the mulberry plant. measuring the length of all the shoots of the test genotypes to get t...

Objectives Root resorption is a dangerous side effect in orthodontics, and maxillary incisors are at the highest risk for root resorption. It is important to understand optimal force considerations for patients with altered root lengths.The purpose of this study was to investigate the effects of root length on stress distribution on roots by means of three dimensional fi...

Shimizuomyces paradoxus showed no inhibitory effect against plant pathogen fungi, such as Fusarium oxysporum f. sp. lycopersici and Alternaria solani. The S. paradoxus culture filtrate showed higher seed germination and seedling growth rates in canola than distilled water and potato-dextrose broth. A conidial suspension of 1.0×10(4)/mL resulted in the highest growth stimulating effects on total...

Root hairs are a low-cost way to extend root surface area (RSA), water and nutrient acquisition. This study investigated to what extend variation exists for root hair formation in rice in dependence of genotype, phosphorus (P) supply, growth medium, and root type. In general, genotypic variation was found for three root hair properties: root hair length, density, and longevity. In low P nutrien...

the research has been done for assessment of effects of different concentrations of indole-3-butyric acid (iba) on rhizogenesis of scions of c. phlomidis in 2010.  the research has been done on randomized complete-blocks for five replications and three treatments with zero, 2000ppm and 3000pmm concentration. different characters such as number of root of each scion, length of root, length of ne...

The aim of this study was to determine the relationship between shoot nitrate concentration, mediated by nitrate supply to roots, and root exudation from Hordeum vulgare. Plants were grown for 14 d in C-free sand microcosms, supplied with nutrient solution containing 2 mM nitrate. After this period, three treatments were applied for a further 14 d: (A) continued supply with 2 mM nitrate (zero b...

the investigation was conducted on wet and dry seasons of ethiopia during the year 2012/2013 at wondo genet agricultural research center nursery site. four levels of cutting size and three levels of cutting positions were arranged in randomized complete block design with three replications. data on seedling height, branch number/seedling, root number/seedling, root weigh/seedling, root length/s...

Low soil P availability is a primary constraint to common bean (Phaseolus vulgaris L.) production in Latin America and Africa. Substantial genotypic variation in bean adaptation to low phosphorus (LP) availability has been linked with root traits that enhance the efficiency of soil foraging. The objectives of this study were to identify quantitative trait loci (QTLs) for P accumulation and asso...
