Newswise — Levels of flavonoids increase over time in tomato crops grown in organically farmed fields, according to a rare long-term study scheduled for publication in the July 18, 2007 issue of ACS’s Journal of Agricultural and Food Chemistry, a bi-weekly publication.新闻立层次黄酮随时间而增加番茄作物种植有机养殖场,据一位难得的长期研究,发表原定于2007年7月18日发出了加勒比国家的日刊农业和食品化学,每两周出版. Other research has suggested that consumption of flavonoids may protect against cancer, heart disease, and other age-related diseases.其他的研究表明消费类黄酮可以防止癌症,心脏病和其他与年龄有关的疾病.

In the new study, Alyson E. Mitchell and colleagues compared levels of key flavonoids in tomatoes harvested over a 10-year period from two matched fields - one farmed organically and the other with conventional methods that included commercial fertilizers.在这项新研究中,alysone.米切尔和他的同事相比水平的关键黄酮西红柿收获逾10年,由两个匹配领域的一个有机耕作及其他常规方法,其中包括商业肥料. The research focused on tomatoes because per capita consumption in the United States is so high, second only to potatoes.这项研究的重点是蕃茄,因为人均消费在美国是如此之高,仅次于土豆. Researchers analyzed organic and conventional tomatoes that had been dried and archived under identical conditions from 1994 to 2004.研究人员分析了有机和传统番茄已风干存档,并在相同的条件下,从1994年到2004年.

“The levels of flavonoids increased over time in samples from organic treatments, whereas the levels of flavonoids did not vary significantly in conventional treatments,” their report stated."各级黄酮俱增样品中的有机处理,而各级黄酮并无明显差别,在常规疗法",其报告称. Increases corresponded with the accumulation of soil organic matter in organic plots and with reduced fertilization rates.加相符积累土壤有机质的有机情节,并减少施肥量. “Well-quantified changes in tomato nutrients over years in organic farming systems have not been reported previously.”"小康量化变化番茄营养多年来,在有机农业系统已不是先前传出"
