Hevea brasiliensis is the main commercial source of natural rubber. Reactive oxygen species (ROS) scavenging systems are involved in various biotic and abiotic stresses. Genetic engineering was undertaken to study the strengthening of plant defences by antioxidants. To that end, Hevea transgenic plant lines over-expressing a Hevea brasiliensis cytosolic(More)
This study aims to (i) determine the effects of incorporating 47 Mg ha−1 acacia green waste biochar on soil physical properties and water relations, and (ii) to explore the different mechanisms by which biochar influences soil porosity. The pore size distribution of the biochar was determined by scanning electron microscope and mercury porosimetry. Soil(More)
Potential benefits of biochar and compost soil amendments may not be realised in high-input perennial horticultural systems such as an apple orchard. Mechanistic understanding of how biochar affects tree physiology is deficient. We determined the effects of biochar amendment on crop yields, growth and tree physiology of a high-input perennial horticultural(More)
