This case is not isolated. Around the same time, certain varieties of maize could be found with ubiquity across part of South America, suggesting a highly frequented and established trade route existed. Phytolith data from the southeastern United States suggest that two different lineages of maize were introduced from two different sources.
Seed dormancy is an evolutionary adaptation that prevents seeds from germinating during unsuitable ecological conditions that would typically lead to a low probability of seedling survival. [1] Dormant seeds do not germinate in a specified period of time under a combination of environmental factors that are normally conducive to the germination ...
Xenia effects in maize. Xenia (also known as the xenia effect) in plants is the effect of pollen on seeds and fruit of the fertilized plant. [1] The effect is separate from the contribution of the pollen towards the next generation.
Input, output, and biological silicon fluxes, with possible balance. Total silicon inputs = total silicon outputs = 15.6 Tmol Si yr −1 in reasonable agreement with the individual range of each flux. White arrows represent fluxes of net sources of dissolved silicic acid and/or of dissolvable amorphous silica and of dissolved silicic acid ...
All chlorides pendant to silicon hydrolyze, but the geminal chlorine on carbon failed to hydrolyze, and the vicinal chlorine eliminated to ethene: beta-silicon effect. The same behavior appeared with n-propyltrichlorosilane. The α and γ isomers resisted hydrolysis, but a hydroxyl group replaced the β chlorine: Scheme 3. Beta silicon effect
Sierra Mixe corn is a traditional variety of maize grown in the Sierra Mixe region of Mexico, especially the town of Totontepec Villa de Morelos. It is known locally as olotón and has been grown by indigenous farmers for thousands of years.
A seed crystal is a small piece of single crystal or polycrystal material from which a large crystal of typically the same material is grown in a laboratory. Used to replicate material, the use of seed crystal to promote growth avoids the otherwise slow randomness of natural crystal growth, and allows manufacture on a scale suitable for industry.
