greenhouse experiment was conducted to assess the response of wheat to tank mixture of herbicides with insecticide and manure in ferdowsi university of mashhad, iran. the experiment consisted of 8 treatments: 1- tribenuron methyl (15-20 g ha-1) + clodinafop propargyl (0.8 l ha-1) 2- tribenuron methyl + clodinafop propargyl + fenitrotion (1.2 l ha-1) + librel (1 kg ha-1) 3- tribenuron methyl + c...

peppermint (mentha piperita l.) is one of the most important plants producing essential oil. an experiment was carried out using a randomized complete block design with 3 replications to study the effect of salinity stress on growth parameters, essential oil percent of peppermint. 4 levels of salinity solution containing 0, 50, 100 and 200 mmol nacl was applied in irrigation plantings in a gree...

The present study investigates the effects of Glomus mosseae and Glomus intraradices on the resistance of green basil plants to salinity stress. The findings suggested that there was an interaction of effects between mycorrhiza fungi inoculation and salt stress on the physiological characteristics of Ocimum basilicum L. On one hand, salinity decreased percentage of root colonization, root lengt...

Citrus plants are widely cultivated around the world and, however, are one of the most salt stress sensitive crops. To improve salinity tolerance, transgenic Carrizo citrange rootstocks that overexpress glyoxalase I and glyoxalase II genes were obtained and their salt stress tolerance was evaluated. Molecular analysis showed high expression for both glyoxalase genes (BjGlyI and PgGlyII) in 5H03...

Genetic relationships between plant height and root morphology were investigated in a diverse set of wheat germplasm [199 double-haploid progeny derived from a cross between Avalon and Cadenza (Triticum aestivum L.), Rht near-isogenic lines (NILs), and accessions from the Watkins Collection] to investigate whether Rht genes controlling shoot height also control seedling root growth. A germinati...

Seed priming improves vigor, but priming agents may differ greatly in their effectiveness. The present study was performed to unravel the physiological basis of vigor improvement by priming sunflower achenes with pre-optimized levels of hydrogen peroxide (H2O2), salicylic acid (SA), thiourea (TU), gibberellic acid (GA3), ascorbic acid (AA), sodium chloride (NaCl), freezing and heating. Most of ...

Centaurium erythraea plants obtained by indirect organogenesis are described in the paper. The plants were initiated from a single adventitious shoot regenerated from callus derived from the cotyledon of a 30-day-old seedling. The shoot was multiplied on MS medium supplemented with IAA (0.1 mg·L-1) and BAP (1.0 mg·L-1). The multiplication rate (28 shoots per culture within 4 weeks) was highest ...

A segregating population of 136 recombinant inbred lines derived from a cross between the durum wheat cv. "Simeto" and the T. dicoccum accession "Molise Colli" was grown in soil and evaluated for a number of shoot and root morphological traits. A total of 17 quantitative trait loci (QTL) were identified for shoot dry weight, number of culms, and plant height and for root dry weight, volume, len...

The Experiment with nutrient solution was conducted in the glasshouse of the University of Applied and life Science, Vienna, Austria to evaluate the effect of water stress on root and shoot development of seven tomato cultivars. The stress levels were 20, 25 and 30 minutes (withholding water) as low, medium and severe stress. The experiment revealed that the cultivars BR-4 and BR-5 showed compa...
