也種過violacea, 雖種死了但到現在還記得香味,香味上的確是bellina 優勝.正如網上所說, violacea 多了一種似肉桂的香料味, 較濁較濃, 不堪多聞; bellina 的香味較簡單, 但較清新較"輕盈", 百聞不厭, 揮發性很強, 而且毋須太陽直射下已有香味, 甚至晚上也有淡淡的香味,真是不可多得,愛香人必種.
以下引述的化學分析, 印證了我的感覺:
"The lemony fragrance of P. bellina is composed almost completely of geraniol (64%) and linalool (32%)... The spicy fragrance ofP. violacea also contains these compounds but is dominated by elemicin (3,4,5-trimethoxy-phenylprop- 1 - ene; 55%) and cinnamyl alcohol (27%). " 肉桂醇?無睇過答案都認出肉桂味D鬼佬真係堅, 唔講我真係諗唔到
