Effect of growth unit characteristics and light environment on leaf fall in the evergreen mango tree
1 month 3 weeks ago

Leaf fall in the evergreen mango (Mangifera indica L.) is affected by physiological age and light environment. Details of these effects need to be determined. Previous studies have not described the dynamics of annual leaf fall of these trees. Our work aimed to decipher the effects of architectural and environmental factors on leaf fall at the scale of the growth unit (GU) during a year. Our experiment began by describing the initial states of 240 GUs, sampled from five mature ‘Cogshall’ mango trees at three depths, expressed as 1, 2, or 4 GU from the terminal GU along the branch.

Apple trees in garden-orchard system improve soil quality and yield of organic radish preceded by lettuce
1 month 3 weeks ago

Maintaining healthy soil is a major challenge in agriculture. Tree-based intercropping is very promising to ensure high production and conserve soil quality, as shown in agroforestry systems. Trees improve soil fertility through the input of organic matter by litterfall and root turnover, which enhance the soil microbial activity. This study aims to evaluate the effects of apple trees (Malus × domestica Borkh. ‘Golden Delicious’) on soil qualities and their potential to improve the yield of an unfertilized organic radish crop (Raphanus sativus L. ‘Ostergruss’).

Transcriptomic and physiological responses of Diplotaxis tenuifolia under heat stress
1 month 3 weeks ago

To determine strategies to increase plant tolerance to high temperature we must examine plant physiological and metabolic processes. High temperature leads to an alteration in photosynthesis, modification of plant metabolism, plant growth reduction, and overall reduction in the quality of horticultural products. Diplotaxis tenuifolia L., commonly known as wild rocket, is a member of the mustard family, Brassicaceae. This plant is cultivated as a baby-leaf salad. Our goal in this study was to understand the physiological and molecular responses in this plant when subjected to heat stress.

Effect of leguminous green manure crops on white cabbage in organic vegetable production in southwestern Germany
7 months 3 weeks ago

Vegetables require high amounts of nitrogen (N) and rather low amounts of phosphorus (P). Therefore, fertilization with farmyard manure often results in nutrient imbalances, commonly seen in P oversupply. Leguminous green manures increase the nutrient supply of the successive vegetable crop by the mineralization of residues and the exclusive N input into the soil by biological N2 fixation. This may reduce the need for organic fertilizers in vegetable production and contribute to more balanced nutrient flows.
