Cereal crops are significant contributors to global diets. As climate change disrupts weather patterns and wreaks havoc on crops, the need for generating stress resilient, high yielding varieties is more urgent than ever. One extremely promising avenue in this regard is to exploit the tremendous genetic diversity expressed by the wild ancestors of...

Sugar supply is a key component of hypoxia tolerance and acclimation in plants. However, a striking gap remains in our understanding of mechanisms governing sugar impacts on low-oxygen responses. Here, we used a maize (Zea mays) root-tip system for precise control of sugar and oxygen levels. We compared responses to oxygen (21 and 0.2%) in the pres...

Two experiments (Expts. 1 and 2) were conducted at different times with avocado (Persea americana Mill. cv. Choquette) trees in containers to test the effects of leaf pruning immediately after removing trees from short-term flooding on tree recovery. Trees in each experiment were divided into two flooding treatments: (1) flooded, or (2) non-flooded...

Three experiments (Expts. 1, 2 and 3) were conducted to test the effects of removing a portion of the leaf canopy of avocado trees (Persea americana Mill.) prior to flooding on plant stress, survival and recovery from short-term flooding. Trees in each experiment were divided into two flooding treatments: (1) flooded, or (2) non-flooded. Trees in e...

Periodic flooding occurs in many areas where avocado (Persea americana Mill.) trees are commercially grown. This depletes oxygen from the root zone which can result in severe tree stress or death. Removing a portion of the canopy has been recommended for rehabilitating flood-damaged avocado trees. Preliminary studies with plants in containers have...

Growth parameters and quantum efficiency measurements of the photosynthesis were evaluated on the emergent macrophyte Ludwigia decurrens under different concentrations of nitrogen (0 mg/L, 465 mg/L y 930 mg/L). Growth was determined as measurements of total length and leaf area, and the emission of chlorophyll fluorescence was used as a measure of...

The ecological interactions present in agroecosystem with cultivated plant species of different functional types (policulture), are important determinants of arthropods diversity, compared to monocultures or one functional type systems. The arthropod diversity in monoculture and polyculture systems was studied using corn (Zea mays) and bean (Phaseo...
