abstract germination and emergence of cold tolerant lentil genotypes sometimes experiences low temperatures and variable rainfalls in the fall planting. this study was conducted to evaluate the effects of drought stress on germination stage of lentil genotypes. experiment was carried out with 18 lentil genotypes under five levels of water potential (0 , -0.4 , -0.8 , -1.2 , -1.6 mpa) using peg ...

The use of local seed provenances is often recommended in restoration and habitat creation because they are thought to be better adapted to local habitat conditions. However, spatial scales and the degree of population differentiation are not well known and germination is often not included in comparisons between provenances. We analysed germination as a key trait of plant development in five p...

both poor germination and crop establishment due to water stress and salinity are among the most important limitations for production in semi-arid regions such as iran. to evaluate the response of four genotypes of triticale (et-82-15، et-82-8، et-79-17 and juanillo-92) to different water potentials caused by salinity and/or drought and recognizing the germination and seedling establishment, a ...

Rapid germination is important for both direct seeded rice in the field and production of germinated brown healthy food. This study aims to evaluate genotypic differences speed identify characteristics that determine speed. Seven experiments were conducted (i) impact dehulling on water absorption germination, (ii) variety consistency across crops grown three years, (iii) effect grain size. Germ...

Three terrestrial plant species, oat (Avena sativa ), Chinese cabbage (Brassica campestris cv. chinensis) and lettuce (Lactuca sativa), were exposed to different concentrations of herbicide TCA (sodium trichloroacetate) in a growth test according to guideline OECD # 208. Classical (i.e. germination and biomass) and biochemical (i.e., antioxydant enzyme activities) endpoints were investigated. G...

Germination rate in contaminated soils cannot be used as the sole indicator to select suitable species for phytoremediation trials, since it does not predict the plant development after germination. As a result, most screening tests for selection of specie with phytoremediation potential to treat contaminated soils include germination rate and biomass production. These screenings take several m...

To assess the potential for carry-over of loblolly pine (Pinus tuedu L.) and shortleaf pine (Pinus echinatu Mill.) seeds from one year to the next, seed viability was determined by germination tests following field storage for up to 21 months. Treatments included seeds stored (i) in a freezer, (ii) on the forest floor, (iii) 1.8 m above the forest floor and exposed to precipitation, and (iv) 1....

University rankings generally present users with the problem of placing the results given for an institution in context. Only a comparison with the performance of all other institutions makes it possible to say exactly where an institution stands. In order to interpret the results of the SCImago Institutions Ranking (based on Scopus data) and the Leiden Ranking (based on Web of Science data), i...
