INTRODUCTION There is an increasing need to recirculate and reuse nutrient solutions in order to reduce environmental and economic costs. However, one of the weakest points in hydroponics is the lack of information on managing the nutrient solution. Many growers and research scientists dump out nutrient solutions and refill at weekly intervals. Other authors have recommended measuring the conce...

Melon (Cucumis melo L.) is a protected crop in China with high economic value. Agrobacterium-mediated genetic transformation powerful tool to improve agronomic traits and obtain elite germplasm. However, current protocols melons are inefficient highly genotype-dependent. To melon, we tested different infiltration methods for transformation. Among these methods, micro-brushing sonication 20 s, f...
