Maintained root length density contributes to the waterlogging tolerance in common wheat (Triticum aestivum L.)

Root growth, soil water variation, and grain yield response of winter wheat to supplemental irrigation

“…The soil water content (SWC) strongly affects the distribution of roots (Lv et al, 2010;Wang et al, 2004). Drought stress or waterlogging restricts root growth and reduces root density (Hayashi et al, 2013;Ma et al, 1999;Xue et al, 2003). Moderate SWC can increase root density, particularly in the deep soil layers, favors soil water absorption at depth and increases grain yield and WUE Qi et al, 2012;Zhang et al, 2009).…”

Effect of pre- and post-heading waterlogging on growth and grain yield of four millets

“…a data were calculated from cross sections of crown roots by microscope observation as showed in Figure 5. (Hayashi et al, 2013). Our results suggest that sustained plant growth may be important for grain formation during vegetative growth under waterlogging.…”

“…Hayashi et al (2013) reported a correlation between root length density and waterlogging tolerance in wheat. In wetland species, the ability to form adventitious roots under flooded soil conditions was very closely related to the flooding frequency of their natural habitat (Visser et al, 1996).…”

“…Before research at the cellular level, the function of roots should be investigated since waterlogging changes the root environment directly and reduces root growth, shoot growth, and final grain yield for several crops (Cannell, Belford, Blackwell, Govi, & Thomson, 1985;Setter & Waters, 2003;Trought & Drew, 1980). It is also well established that flooding imposes water stress in the shoot since water absorption is decreased in plants with smaller root system and/or physiologically injured roots (Hayashi et al, 2013;Polacik & Maricle, 2013). Maintenance of root growth is considered an important adaptive response to excess water in several crops (Daugherty & Musgrave, OPEN ACCESS tolerance and the effect of pre-and post-heading waterlogging on growth and grain yield among four millets.…”

Contribuição direta do fósforo microbiano do solo na nutrição de plantas de trigo

“…Esta redução pode ser atribuída também à translocação de P da raiz para a parte aérea, visto que a planta possui mecanismos que atuam na regulação dos teores de P na parte aérea para manutenção do aparato fotossintético (Silva et al, 2008) e a senescência de raízes, por causa do alagamento do solo e redução da aeração (Hayashi et al, 2013). No entanto, maiores evidências do efeito da morte da biomassa microbiana no fornecimento de P para as plantas são prejudicadas em função do compartimento P da BMS ser pequeno em relação aos demais compartimentos e pela variabilidade deste tipo de análise.…”
