Global cooling event 4,200 years ago spurred rice evolution spread across Asia
2020/5/29
A major global cooling event that occurred 4,200 years ago may have led to the evolution of new rice varieties and the spread of rice into both northern and southern Asia, an international team of res...
真空预冷处理对青花菜贮藏期间生理活性的影响（Effect of Vacuum Pre-cooling on Physiological Activities of Broccoli during Storage）
青花菜 真空预冷 生理活性
2009/11/3
将真空预冷技术应用于冷藏保鲜青花菜的预处理中，研究了真空预冷处理对青花菜在5℃贮藏期间生理活性的影响。结果表明：与不进行预冷处理样品相比，真空预冷抑制了青花菜的呼吸速率、乙烯释放量，其中失重率减少了2.18%；改善了青花菜的感官品质，减少了叶绿素和维生素C的损失，并通过调节抗氧化酶的活性起到了延缓青花菜衰老的作用。
Sterility Caused by Cooling Treatment at the Flowering Stage in Rice Plants:IV. Effects of the starting time of cooling, morning and evening, and the soil temperatures and the light conditions after cooling on the fertility
Cool temperature Diurnal variation Flowering stage Rice Sterility
2009/8/6
Effect of the starting time of cooling at the flowering stage together with the effects of water temperatures and light conditions after cooling on the fertility percentage were examined. The fertilit...
Male Sterility Caused by Cooling Treatment at the Young Microspore Stage in Rice Plants : XXIX. The mechanism of enhancement in cool tolerance by raising water temperature before the critical stage
Cool injury Cool tolerance Microspore Pollen Rice Sterility Water temperature
2009/8/6
Potted rice plants were grown in the phytotron with different water temperatures in a range from 18 to 25°C during the period from the spikelet differentiation stage to just before the young microspor...
Sterility Caused by Cooling Treatment at the Flowering Stage in Rice Plants:III. Establishment of a method of in vitro pollen germination
Boric acid Incubation temperature In vitro germination Pollen Rice
2009/8/6
Rice pollen grains germinated more than 80% with low variation (standard deviation less than 10%) and their pollen tubes elongated to more than 150μm within one hour with a simple medium composed of 1...
Male Sterility Caused by Cooling Treatment at the Young Microspore Stage in Rice Plants:XXX. Relation between fertilization and the number of engorged pollen grains among spikelets cooled at different pollen developmental stages
Anther Cool injury Cool temperature Microspore Pollen Rice Sterility
2009/8/6
Cooling treatments at different stages of pollen development lowered the percentage of fertilized spikelets through decreasing the number of engorged pollen grains per anther at anthesis. Cooling duri...
Male Sterility Caused by Cooling Treatment at the Young Microspore Stage in Rice Plants:XXXI. Four components participating in fertilization
Cooling injury Cooling tolerance Fertilization Microspore Pollen Rice
2009/8/5
We divided the developmental processes from microspore differentiation to fertilization into 4 phases and defined the component relating to fertilization in each phase. The percentage of fertilization...
Influence of Nitrogen Application on Anther Length, Anther Width and Number of Engorged Pollen Grains as Characters Related to Cooling Injury in Rice Plants
Anther legth Anther width Basally applied nitrogen Cooling injury Cooling tolerance Number of engorged pollen grains
2009/7/16
Anther length, anther width, and number of engorged pollens were reported to have a relationship to cooling injury of rice. The effects of nitrogen application on anther size and number of pollens wer...
