The possible effects of seed priming on mitigating the effects of drought stress on germination and early seedling growth of two rangeland plants were evaluated in a laboratory research during 2015-16 growing season. The research was conducted as a 2×3×3 factorial experiment based on completely randomized design with three replications. The first factor was plant type (Festuca ovina and Bromus ...

rapid germination is an important factor determining the final yield. the most important abiotic stress threatening lentils is drought and temperature. therefore, this study was performed with the aim of investigating effects various thermal treatments (5, 10, 15, 20, 25 and 30°c) and four levels of drought (0, -4, -8, -12 and -16 bar) on percentage and germination rate of lentil genotypes. a s...

The adverse effects of salinity and PEG-induced water stress on growth of Matricaria chamomilla were assessed at the germination stage using osmotic solution of NaCl (0, -0.175, 0.358, -0.541, -0.716 MPa), and polyethylene glycol (PEG 6000) (0, -0.05, -0.1, -0.2, -0.3 MPa), respectively. Effect of NaCl salinity stress (0, 40, 80, 120 and 190 mM NaCl) at early growth stage of chamomile was also ...

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...

In order to study of hydropriming and halopriming on germination and early growth stage of wheat (Triticum aestivum L.) an experiment was carried out in laboratory of the Department of AgroNomy and Plant breeding, Shahrood University of Technology. Seed treatments consisted of T1: control (untreated seeds), T2: soaking in distilled water for 18 h (hydropriming). T3: soaking in -1.2 MPa solution...

To test the germination capacity and its temperature dependence in Mediterranean plants, sixteen species representative of a diversity of habitats of the Balearic Islands were selected. The percentage of germination, the half-response time and the dormancy period of these species were studied at three alternating temperatures: 5-15 C, 10-20 C and 15-25 C. Large differences were found among spec...

in order to further understand the emergence and germination of sugar beet monogerm cultivars under moisture stress, the current study was carried out at three stages. at the first stage, the quality of germination of three monogerm cultivars (rizofort, rasoul and zarghan) were studied under five moisture stress levels (0, -2, -4, -6 and -8 bars) in germinator at 15°c by between-paper method. a...
