Drought and floods affect the growth yield of maize, affecting food security. Therefore, it is crucial to assess maize’s drought waterlogging status in various stages. We used phenological daily meteorological data spatial analysis identify conditions spring maize Northeast China eight calculated crop water surplus/deficit index national standard for waterlogging. The results indicate a signifi...

The yield response of various crops to salinity under field conditions is affected by soil processes and environmental conditions. The composition of dissolved ions depend on soil chemical processes such as cation or anion exchange, oxidation-reduction reactions, ion adsorption, chemical speciation, complex formation, mineral weathering, solubility, and precipitation. The nature of cations and ...

Urban green infrastructures (UGI) can effectively reduce surface runoff, thereby alleviating the pressure of urban waterlogging. Due to shortage land resources in metropolitan areas, it is necessary understand how utilize limited UGI area maximize waterlogging mitigation function. Less attention, however, has been paid investigating threshold level capacity. Additionally, various studies mainly...

In rosette plants, root flooding (waterlogging) triggers rapid upward (hyponastic) leaf movement representing an important architectural stress response that critically determines plant performance in natural habitats. The directional growth is based on localized longitudinal cell expansion at the lower (abaxial) side of the leaf petiole and involves the volatile phytohormone ethylene (ET). We ...

Superstandard conditions refer to extreme rainfall and river flooding that exceed the flood control system or works. In order explore influence of superstandard on urban waterlogging, based MIKE FLOOD platform, this paper takes downtown area Zhoukou as research object, it conducts waterlogging simulation in under once 20 years 50 combined with ultra-high water level river. The results inundatio...

Commercial and non-commercial plants face a variety of environmental stressors that often cannot be controlled. In this study, transgenic hybrid poplar (Populus × euramericana 'Guariento') harboring five effector genes (vgb, SacB, JERF36, BtCry3A and OC-I) were subjected to drought, salinity, waterlogging and insect stressors in greenhouse or laboratory conditions. Field trials were also conduc...

Flooding regimes of different depths and durations impose selection pressures for various traits in terrestrial wetland plants. Suites of adaptive traits for different flooding stresses, such as soil waterlogging (short or long duration) and full submergence (short or long duration – shallow or deep), are reviewed. Synergies occur amongst traits for improved internal aeration, and those for ano...

Phenylalanine ammonia lyase (PAL) is the first enzyme in phenylpropanoid pathway and plays a critical role plant growth, development stress defence. However, there have been few reports of PAL gene family lucerne (also known as alfalfa, Medicago sativa L.), one most important forage legume species worldwide. In this study, we report that encoded by seven genes: MsPAL1–MsPAL7. Furthermore, compr...

This work determines the ffects of long-term anoxia conditions--21 days--on Strategy I responses to iron (Fe) deficiency in Citrus and its impact on Fe uptake and distribution. The study was carried out in Citrus aurantium L. seedlings grown under flooding conditions (S) and in both the presence (+Fe) and absence of Fe (-Fe) in nutritive solution. The results revealed a strong down-regulation (...
