Six selected cultivars of rice namely BPT-5204, MTU-7029, CSR-30, Narendra Usar Dhan-3, Rajendra Bhagwati and Pusa Basmati-1 were screened for salinity tolerance on the basis of in vitro seed germination and seedling growth under different salt stress (02.5%) created by a salt mixture of NaCl, CaCl2, and Na2SO4 in 7:2:1 ratio. At 2% salt stress, germination was only observed in cultivars CSR-30...

Pearl millet is one of the most important cereals grown in drought-prone areas and is the staple grain for million of people in West Africa and India. Breeding for drought-prone environments is constrained by lack of suitable selection indices of drought stress resistance. The present study is conducted to determine the reliability of in vitro screening method for initiating drought breeding pr...

to investigate the effects of different salinity levels of nacl on germination of safflower (cv. esfahan 24) seeds under three different incubation methods, a factorial experiment was carried out based on a complete randomize design with three replications. salinity levels were 0, 5, 10, 15 and 20 dsm-1 (nacl) and incubation methods were sandwich method, and using petri dishes with open or clos...

To investigate mechanisms involved in establishing polar organization in Arabidopsis embryos and seedlings, we used promoter trapping to identify molecular markers (beta-glucuronidase fusion genes) expressed in spatially restricted patterns along the apical-basal axis. Three markers were identified that are expressed, respectively, in the embryonic and seedling root tip (POLARIS), cotyledons an...

One hundred and sixty two genotypes of different Lens species were screened for salinity tolerance in hydroponics at 40, 80 and 120 mM sodium chloride (NaCl) for 30 d. The germination, seedling growth, biomass accumulation, seedling survivability, salinity scores, root and shoot anatomy, sodium ion (Na+), chloride ion (Cl-) and potassium ion (K+) concentrations, proline and antioxidant activiti...

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...

microorganisms has positive role on seed germination and growth of plants. In the present study, its efficacy on seed germination and seedling growth of Albizia lebbeck in the nursery was studied. The seeds were sown in polybags filled with a mixture of forest soil and cow dung (3:1) and treated with 0.1%, 0.5%, 1%, 2%, 5% and 10% concentrations of MI. Most of the parameters studied (seed germi...

This investigation was carried out to determine the effects of gamma radiation on germination and physiological characteristics of wheat seedlings. Two wheat genotypes (Roshan and T-65-58-8) were irradiated with 100, 200, 300 and 400 Gy. The results showed that MGT (Mean Germination Time), root and shoot length, and seedling dry weight decreased with increasing radiation doses but final germina...

Despite the accumulation of data on the genetic and molecular understanding of heterosis, there is little information on the regulation of heterosis at the physiological level. In this study, we performed a quantitative analysis of endogenous gibberellin (GA) content and expression profiling of the GA metabolism and signaling genes to investigate the possible relationship between GA signaling a...
