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.
Silica is an important nutrient utilized by plants, trees, and grasses in the terrestrial biosphere. Silicate is transported by rivers and can be deposited in soils in the form of various siliceous polymorphs. Plants can readily uptake silicate in the form of H 4 SiO 4 for the formation of phytoliths.
The plants that were affected by either mosaic virus (carried by aphids) or bacterial wilt disease (carried by cucumber beetles) were infected on their own to replicate natural conditions and all plants were grouped into three categories: healthy plants sprayed to prevent insect herbivory, plants infected with mosaic disease, and plants ...

Dust from treated seed is known to have caused at least some health and safety problems particularly from crops such as maize drilled during the main honey flows. Improvements to pneumatic drills to reduce dust release, and improvements to seed treatment compounds to prevent the compound breaking up into dust (dust-off) have been introduced in ...
True dormancy or inherent (or innate) dormancy is caused by conditions within the seed that prevent germination even if the conditions are favorable. [7] Imposed dormancy is caused by the external conditions that remain unsuitable for germination [8] Seed dormancy can be divided into two major categories based on what part of the seed produces dormancy: exogenous and endogenous. [9]
The International Maize and Wheat Improvement Center (known – even in English – by its Spanish acronym CIMMYT for Centro Internacional de Mejoramiento de Maíz y Trigo) is a non-profit research-for-development organization that develops improved varieties of wheat and maize with the aim of contributing to food security, and innovates agricultural practices to help boost production, prevent ...
They combined the phytoene synthase (psy) gene from maize with crtl gene from the original golden rice. Golden Rice 2 produces 23 times more carotenoids than golden rice (up to 37 μg/g) because psy gene of maize is the most effective gene for carotenoid synthesis, and preferentially accumulates beta-carotene (up to 31 μg/g of the 37 μg/g of ...
