Root Adaptation via Common Genetic Factors Conditioning Tolerance to Multiple Stresses for Crops Cultivated on Acidic Tropical Soils

Comparative Evaluation of Common Savannah Grass on a Range of Soils Subjected to Different Stresses II: Root Zone Physical Condition

The root zone physical condition influences root development and function, which affects turfgrass growth, quality and performance. The temporal variability of root zone properties was investigated in a factorial experiment combining sand layering compaction and moisture stress on the performance of Savannahgrass (SG) (Axonopus compressus), Bermudagrass (BG) (Cynodon dactylon (L.) Pers.) (cv. T...

Agrochemicals and Bacterial Diversity in Cultivated Tropical Soils

Soil alkalinity and salt tolerance: adapting to multiple stresses.

Bui's commentary [1] arises from an observation made in our paper on the evolution of salt tolerance in grasses. We described the 'paradox' of salt tolerance ; that it evolves often in nature but is hard to breed into crops [2], although there has been recent success in increasing the tolerance of wheat on salt-affected soils in Australia [3]. Bui suggests that one reason for lack of success in...

Differential Soil Acidity Tolerance of Tropical Legume Cover Crops

In tropical regions, soil acidity and low soil fertility are the most important yield-limiting factors for sustainable crop production. Using legume cover crops as mulch is an important strategy not only to protect the soil loss from erosion but also to ameliorate soil fertility. Information is limited regarding tolerances of tropical legume cover crops to acid soils. A greenhouse experiment wa...

Plant Adaptation to Multiple Stresses during Submergence and Following Desubmergence

Plants require water for growth and development, but excessive water negatively affects their productivity and viability. Flash floods occasionally result in complete submergence of plants in agricultural and natural ecosystems. When immersed in water, plants encounter multiple stresses including low oxygen, low light, nutrient deficiency, and high risk of infection. As floodwaters subside, sub...
