Aim of study: Despite protection by international agreements, millions orchid tubers are harvested from their natural distribution areas each year. Of these species, Himantoglossum robertianum is locally threatened due to overharvesting and requires precautionary measures ensure its protection. Reproduction the species in an asymbiotic environment imperative for providing ex-situ There no studi...

Lack of chickpea cultivars tolerant to extreme freezing is a limiting factor for autumn planting of this crop in cold areas. In this study, 58 Kabuli-type chickpea genotypes and a control (an international sensitive genotype) were planted in pots and first exposed to -10°C and then to -15°C after being acclimated in natural conditions. No destructive effect of -10°C was observed in plants. So, ...

Abstract Due to challenges associated with lavender propagation, Texas hybrid (lavandin) growers require revised propagation information. Therefore, experiments investigated effects of media and plant growth regulators (PGR) on rooting three different lavandin (Lavandula x intermedia) cultivars. PGRs applied cuttings were naphthaleneacetic acid (NAA), or indole-3-butyric (IBA) at concentrations...

Eight coals used as carriers in legume inoculants promoted the survival of Rhizobium phaseoli on pinto bean seeds. Although peat was more protective, most coal-based inoculants provided >10 viable rhizobia per seed after 4 weeks.

Oil and gas production has an adverse impact on the ecological state of Russian Arctic. The local natural materials, such as peat, moss, reindeer moss are considered naturel sorbents in wastewater treatment technologies. sorption properties these materials were studied. isotherms at different initial concentrations pollutant (250, 50, 0.5 mg/L) constructed. patterns changes intensity oil produc...

laboratory experiments were performed to determine the effect of various scarification treatments at four temperature regimes on germination of licorice seeds . a randomized complete block design with four replications was used. germination counts were made every day for 2 weeks. at 50c, none of the chemically and mechanically scarified and non scarified seeds germinated. at 15, 25, and 350...
