5. Targeted and non-targeted approaches to ImprUV the nutritional profile of greenhouse crops
University essay from Örebro universitet/Institutionen för naturvetenskap och teknikAbstract : This work was made to discover if greenhouse crops, particularly broccoli and Chinese cabbage, can change their metabolism and therefore their nutritional profile depending on what ultraviolet radiation (UV) they were exposed during growth. This is important since the world’s population increases and therefore, we need to be able to produce foods with increased nutritional quality. READ MORE
