Although the effect of cold stratification on seed dormancy release has been extensively studied for many species, knowledge of the role of stratifying temperature, soil moisture content and duration of stratification on seed dormancy release at the population level is limited.

Notopterygium incisum is an important Chinese medicinal plant. Its mature seeds have underdeveloped embryos and are physiological dormant. We found the seeds with full developed embryos can germinate after treated by fluridone (FL), an inhibitor of abscisic acid (ABA).

Multi-dimensional phenomena specific to the SGTR accident appeared such as significant thermal stratification in a cold leg in broken loop especially during the operation of highpressure injection (HPI) system. The RELAP5/MOD3.3 code overpredicted the broken SG secondaryside pressure after the start of the intact SG secondary-side depressurization, and failed to calculate the cold leg fluid temperature in broken loop.

The effects of stratification, temperature and storage on seed germination performance were investigated in 3 provenances of Fraxinus angustifolia subsp. oxycarpa seeds. In the first study, seeds were subjected to 9 different periods of cold stratification or warm stratification followed by cold stratification to overcome dormancy.

Dormancy in Cercis siliquastrum seeds is due to the hard, impermeable seed coat and inhibition by endosperm. The effects of acid scarification, cold moist stratification, and the combination of both on breaking dormancy and enhancing seed germination were evaluated.

Tôm, cá thuộc loại máu lạnh (cold-blooded, poikilothermic). Tôm, cá thay đổi nhiệt độ theo môi trường bên ngoài, khác với con người là loại thân nhiệt (warm-blooded, homoiothermic). Nhiệt độ ảnh hưởng tới sự hô hấp, tiêu thụ thức ăn, đồng hoá thức ăn, miễn nhiễm đối với bệnh tật, sự tăng trưởng... Ở miền Nam Việt Nam có thể nuôi tôm quanh năm, miền Bắc thường chỉ nuôi tôm mùa nóng. Ánh nắng mặt trời làm nóng lớp nước trên mặt làm xảy ra hiện tượng phân tầng (thermal stratification): lớp nước trên mặt sẽ nhẹ hơn và...
