Stratification requirements for seed dormancy alleviation in a wetland weed. [PDF]

, 2013
Echinochloaoryzicola(syn.E. phyllopogon) is an exotic weed of California rice paddies that has evolved resistance to multiple herbicides. Elimination of seedlingsthroughcertain weed control methods can limit the spread of this weed, but is contingent on ...

Optimizing Seed Germination and Seedling Growth in Different Kiwifruit Genotypes

Horticulturae, 2021
The presence of dormant embryos in seeds and nonuniformity in seedling growth are the main limiting factors for kiwifruit propagation. Studies on the germination of hybrid genotypes are limited, especially at different ploidy levels.

New insight into stratification of anaerobic methanotrophs in cold seep sediments [PDF]

FEMS Microbiology Ecology, 2011
Methane seepages typically harbor communities of anaerobic methane oxidizers (ANME); however, knowledge about fine-scale vertical variation of ANME in response to geochemical gradients is limited. We investigated microbial communities in sediments below a white microbial mat in the G11 pockmark at Nyegga by 16S rRNA gene tag pyrosequencing and real ...

Non-Deep Simple Morphophysiological Dormancy and Germination Characteristics of Gentiana triflora var. japonica (Kusn.) H. Hara (Gentianaceae), a Rare Perennial Herb in Korea

Plants, 2021
This study investigated the kind of seed dormancy and seed germination of Gentiana triflora var. japonica (Kusn.) H. Hara for developing a seed propagation method. The seeds were collected in October 2020 from plants at Mt. Sobaeksan, Korea.

Predicting the consequences of global warming on Gentiana lutea germination at the edge of its distributional and ecological range [PDF]

PeerJ, 2020
Background Temperature is the main environmental factor controlling seed germination; it determines both the percentage and the rate of germination. According to the Intergovernmental Panel on Climate Change, the global mean surface temperature could ...

Cold-Moist Stratification Improves Germination in a Temperate Terrestrial Orchid [PDF]

Castanea, 2016
ABSTRACT  Seed dormancy is a common evolutionary adaptation in temperate plant taxa. Dormancy mechanisms can prevent seeds from germinating at inopportune times, such as a cold period. We report the influence of pregermination stratification treatments on in vitro seed germination and seedling development in Platanthera chapmanii, a rare temperate ...

Comparison of acid scarification, stratification and endocarp removal on seed germination of three olive cultivars [PDF]

علوم و فناوری بذر ایران, 2020
Present study was conducted to evaluate the effects of chemical scarification (Sulphuric acid 97% for 0, 3, 6 and 9 h at 25°C), removal of endocarp and cold stratification (0, 21 and 31 days at 10°C) treatments on percentage and rate of seed germination ...
