In Brazil there are no studies on the interaction between fungi colonizers of vascular tissues and water deficit
in mango trees.
it corresponds to the water stored at field capacity, throughout the root zone, while the fraction of readily available water (RAW) represents the lower limit of soil water availability, without causing water deficit
(RAW = p.
Field emergence and other agronomical traits decreased from optimum condition of irrigation to mild and high water deficit
stress levels in both cultivars, significantly (Table 5).
Spatial pattern of water deficit
is consistent with soil map.
For all evaluations during the 18 months, no wilt or senescence of the mahogany plants were observed as according to water deficit
and it can be inferred that this species has tolerance to this condition (Albuquerque et al.
The mass of marketable fruits declined by 45% with the variation in irrigation depth from 213 to 135 mm as a result of the effect of water deficit
that caused losses in the production through fruits with blossom-end rot.
Regardless of temperature, with the increase in water deficit
, the 'jurema-de-embira' starts to invest in the production of roots, whose effect is more evident between the osmotic potentials of -0.
IAA, GA and SA contents gave significant reduction under lower irrigation levels but ABA increased under water deficit
1 billion people globally suffered from a water deficit
for at least 30 days a year.
Therefore, it has become imperative to explain the responses and adaptation of crops to water deficit
, and take actions to improve the drought resistance ability of crop plants and to ensure higher crop yields against unfavorable environmental stresses.
Drought such as other environmental stresses has deleterious effect on crop yield and in many areas, water deficit
is one of the important factors which declines yield.
Specific topics include a tool for detecting crop water status using airborne high-resolution thermal imagery, the physiological response of mungbean (Vigna radiata) to water deficit
stress and Meloidogyne javanica infection, the effects of climate change on flood frequency in the Luvuvhu River Catchment in South Africa's Limpopo Province, the role of soil database classification in unsaturated zone modeling, and Nigeria as a case study of media advocacy for sustainable water management in Africa.
They briefed about the results achieved in the framework of cooperation with several international programs and projects aimed at mitigating the effects of climate risks and water deficit
The topics include induced tolerance and priming for abiotic stress in plants, metabolomics and its role in studying plant abiotic stress response, mathematical modeling in the investigation of plant cold tolerance, plant-arthropod interactions affected by water deficit
stress through association with changes in plant free amino acid accumulation, and hydrogen sulfide as a potent regulator of plant responses to abiotic stress factors.
Summary: The nearly rainless months of January and February have hit Lebanese farmers hard, and if the drought persists, experts warn it could further dry up groundwater wells and reservoirs increasing the water deficit
for both household and agricultural use.
