Update on Hormonal Regulation of Branching in Grasses Hormonal Regulation of Branching in Grasses
Axillary meristems, which form in the axils of leaves, play an essential role in plant architecture and reproduction. During vegetative development, axillary meristems give rise to branches, called tillers in grasses, while during reproductive development, axillary meristems give rise to flowering branches or to flowers. The control of branching by axillary meristems is under hormonal, environm...

15 صفحه اولPower Tillers for Demining: Blast Test
Power tillers are very simple and versatile machines with large scale diffusion in developing countries, where they are commonly used both for agriculture and for transportation purposes. A new integrated participatory approach that makes use of and improves local end-users knowledge has been used to design a new robotic system for humanitarian demining applications in Sri Lanka, using power ti...
متن کاملArchitectural Evolution and its Implications for Domestication in Grasses
BACKGROUND The cereal crops domesticated from grasses provide a large percentage of the calories consumed by humans. Domestication and breeding in individual cereals has historically occurred in isolation, although this is rapidly changing with comparative genomics of the sequenced or soon-to-be sequenced genomes of rice, sorghum, maize and Brachypodium. Genetic information transferred through ...
متن کاملMechanisms of drought stress tolerance in cool season grasses
Drought stress is one of the most limiting abiotic stresses affecting growth, production and survival of plants in many areas of the world, and is expected to intensify considering the trend of climate change. Grass species are important for the sustainability of agricultural systems, forage resources for animal farming and landscapes. Grass species adapt to water deficit by different morpholog...
