Períodos de drenagem do solo durante o perfilhamento e características agronômicas de cultivares de arroz irrigado no sistema pré-germinado Soil drainage periods during tillering and agronomic traits of rice cultivars grown with pre-germinated seeds

Ciência Rural, 2008
A retirada da água no perfilhamento é uma prática comumente efetuada pelos produtores de arroz irrigado no Estado de Santa Catarina, visando a estimular o enraizamento, prevenir o acamamento e facilitar a colheita.

Substitution Mapping of a Locus Responsible for Hybrid Breakdown in Populations Derived From Interspecific Introgression Line

Frontiers in Plant Science, 2021
Hybrid breakdown, a form of postzygotic reproductive barrier, has been reported to hinder gene flow in many crosses between wild and cultivated rice. Here, the phenomenon of hybrid breakdown was observed as low-tillering (i.e., low tiller number) in some

Advances in studies on the physiological and molecular regulation of barley tillering

Journal of Integrative Agriculture, 2023
Tillering is a crucial trait closely associated with yield potential and environmental adaptation in cereal crops, regulated by the synergy of endogenous (genetic) and exogenous (environmental) factors.

Impact of Drought Exerted during Spike Development on Tillering, Yield Parameters and Grain Chemical Composition in Semi-Dwarf Barley Mutants Deficient in the Brassinosteroid Metabolism

Agronomy, 2020
Drought is a major factor limiting plant development and negatively affecting crop yield. It was reported that mutants defective in the brassinosteroid (BR) metabolism from several species, including barley (Hordeum vulgare), show improved tolerance to ...
