|
For utilization of buckwheat as vegetable, rutin and minerals of the leaves at growing stages were investigated. The contents of crude protein and crude fat in seed of nine improved kinds of Korean buckwheat were 16.2∼20.4% and 2.2∼2.9% respectively. Ash content (2.4∼4.3%) in the improved kinds were higher than those in the native kinds. Content of crude fiber in the improved kinds were lower than those in the native kinds. Suwon 11 (0.12%) and Suwon 5 (0.11%) had high contents of rutin among the improved kinds. The composition of K, Ca, Mg and Fe in the improved kinds were better than that in the native kinds. Vegetable of the improved kinds had higher content of crude protein than the native kinds. Suwon 10 and 11 among vegetables of the improved kinds contained high amount of crude protein. Swon 5 had the highest content of rutin (0.40%) in the improved kinds. Suwon 5 was tested for the changes of rutin content in growing. Rutin content was 0.40% in the first growing stage, whereas 1.32% in the final rowing stage. Insoluble materials in 10% HCl was also 69.8% in the first growing stage, whereas 4.68% in the final growing stage. Iron and calcium contents were increased with growing of vegetable.
