Abstract:

Sexual reproduction is crucial for plant populations to track and adapt to climate change, but it is uncertain to what degree arctic vascular plants reproduce by seed. Several studies on arctic species show low germination. To re-examine seed germination and evaluate factors limiting sexual reproduction, seeds of 6–22 arctic species were germinated in five different, increasingly more realistic, conditions. Thirteen out of 15 species that were tested in an earlier study in Svalbard, Norway, germinated better in our study. Compared with perceived optimal conditions in a growth chamber, average

The germination percentage of Soybeans is susceptible and affected by many external and internal factors. Screening of three varieties of soybeans (Shimaa, Industrial2, and M103) during laboratory germination and field emergence was conducted to identify varieties with superior performance under four concentrations of gibberellic acid (0, 75, 150, 225 ppm). Experiments were conducted in Field Crops Dept./College of Agriculture/Tikrit University.

Freeze thaw scarification has been observed to increase the germination rate of alfalfa (Medicago sativa L.) seed containing a large proportion of hard (water impermeable) seed in a 7-d laboratory germination test; however, a comparable increase in plant density is not always seen in the field. To investigate this discrepancy, a field experiment with untreated and scarified seed was carried out using cultivars with high (Apica, 35%; Barrier, 32%) and low (Apollo II, 1%; WL316, 0.3%) percentages of hard seed. Plants were counted at the three-trifoliate-leaf and 10% bloom stages in 1992, the pla

The obligate hemiparasite Striga hermonthica is one of the major global biotic threats to agriculture in sub-Saharan Africa, causing severe yield losses of cereals. The germination of Striga seeds relies on host-released signaling molecules, mainly strigolactones (SLs). This dependency opens up the possibility of deploying SL analogs as “suicidal germination agents” to reduce the accumulated seed bank of Striga in infested soils. Although several synthetic SL analogs have been developed for this purpose, the utility of these compounds in realizing the suicidal germination strategy for combatin

Laboratory and field trials were carried out for two years to study the effect of hydro-priming on faba bean germination and field performance in spring sowing. In laboratory trials, the effects of hydro-priming for 0, 8, 16, 24, 36, and 48 h on final germination percentage, germination speed, Timson’s germination index, mean germination time, mean daily germination, synchronization index, and seedling vigor index were studied. All hydro-priming treatments

Abstract:

The effect of salinity on seed germination/emergence in narrow-leaved ash (Fraxinus angustifolia) was studied both under field and laboratory conditions, in order to detect critical values to NaCl exposure. Research Highlights: Novel statistical methods in germination ecology has been applied (i) to determine the effects of chilling length and salinity (up to 150 mM NaCl) on Fraxinus angustifolia subsp. oxycarpa seed emergence, and (ii) to estimate threshold limits treating germination response to salinity as a biomarker. Background and Objectives: Salinity cut values at germination stage had

Abstract:

This article presents the results of research conducted on the germination of Greater Celandine (Chelidonium majus L.), one of the valuable medicinal plant species. It was found that under laboratory conditions, seed germination was high (91.4-93%) with an optimal germination temperature of 25-30°C. Field germination, however, was relatively low (17.7-24.5%), influenced by the seeds' anatomical structure and variable environmental conditions.

Abstract:

Threehorn bedstraw is an important dicotyledonous weed of winter crops in southern Australia, which can be difficult to control in some field crops. Knowledge of the germination ecology of this weed would facilitate development of effective weed control programs. Seed germination in the laboratory was greater for seeds that after-ripened while buried in the soil relative to those that after-ripened on the soil surface. The timing of greatest seed germination in the laboratory was found to coincide with the period of low temperature in the field. Seed germination of threehorn bedstraw was moder

To determine if conditions in California were conducive to this, teliospore emergence and priming were evaluated in the field. A factorial exper
