丝瓜单花的开放时间,有的文献上记载是傍晚7点左右;也有的说应在早晨7—8点盛开。丝瓜究竟何时开花呢?为此,我们仔细调查了当地及温州、杭州等地丝瓜的开花时间,观察结果是棱角丝瓜(Luffa acu-tangula)的花开放时间为傍晚7—8点。丝瓜(Luffacylindrica)的开花时间是上午6—11点钟,阴雨天则白天全天开放。 Loofah single flower opening hours, and some documented in the evening about 7 o’clock; others say should bloom in the morning 7-8. For this reason, we carefully investigated the flowering time of loofah and the locusts in Wenzhou, Hangzhou and other places. The observation result was that flowers of Luffa acu-tangula were open at 7-8 pm in the evening. Loofah (Luffacylindrica) flowering time is 6-11 o’clock in the morning and rainy day is open all day.
