Development of an energy-efficient Plant Light with Plasma-Technology for Horticultural Production

The aim of this project is the development of a high-efficient plasma light for horticultural production.. Currently Plasma International GmbH produces electrodeless plasma lights for general use with an efficiency up to 120lm/W and a spectrum similar to the sun (CRI max.99). To make this technology useful for horticultural needs in greenhouses, light technique needs to be developed further by Consortial Leader Aurion Anlagentechnik and its partner Plasma International.  ...more

Physiological and molecular investigations of African leafy vegetables for quality assurance and losses reductionin postharvest management

African indigenous leafy vegetables (ALV) play a significant role in food security in Africa. They are mainly produced by small-scale farmers and are marketed or traded locally, regionally or even internationally. Currently, the magnitude of postharvest losses of AVLs in Kenya can reach up to 50%, depending on the product.  ...more

7. Water Balance of Trees in Urban Areas

Master Student Konstantin Lang and Dr. Martin Leberecht climbed in Freiburg an approximately 63 m high Douglas fir (Pseudotsuga menziesii) - one of the tallest trees in Germany - to record ultrasonic emissons in four different levels above ground. Ultrasonic emissons in trees are caused by cavitations (gas bubbles in the water-bearing xylem), which are affecting the water transport negatively. Quantity of ultrasonic emissons events can be correlated with drought stress. The aim of these measurements is a better understanding of the water balance in trees, especially in urban areas....more
