日长对甜菊的反应及其变异甜菊[Stevia rebaudiana(Bertoni)Hemsley]是菊科植物,原产南美洲、其叶片能制造六种糖苷,其中最多的为甜菊苷(Stevioside)比蔗糖甜三百倍,其次为瑞包轴A 苷(Rebaudioside A),比蔗糖甜四百五十倍,还有四种糖苷数量较少,尚未定量析出,这种甜味的新作物近年来已引起大家的注意,可能成为我们新的甜味增甜物。日人在冲绳进行研究,试图找出此植物的基本要求与适应性,务求能在亚热带地区栽种得好,因此进行三种日长反应观察,即11,12.5及14小时处理,并与当地天然日照
The Response of Steamed Rehd to Stevia and Its Variation Stevia rebaudiana (Bertoni) Hemsley is a Compositae, native to South America. Its leaves produce six kinds of glycosides, most of which are stevioside three hundred Followed by Rebaudioside A, four hundred and fifty times more sweet than sucrose, and four fewer glycosides, which have not yet been quantitated. The sweet new crop has drawn the attention of people in recent years , May become our new sweetness sweetener. Japan conducted a study in Okinawa to try to find out the basic requirements and adaptability of this plant in order to planted well in the subtropical region. Therefore, three kinds of long-term reaction observation were conducted, that is, 11, 12.5 and 14 hours treatment, sunshine
