在加拿大艾伯塔连续三个产季测定了大田直播的一年生甜茴香的园艺学性状和油的质量。只估计了在灌溉和施肥条件下茴香的平均生势和生长状况。在收割时,伞形花序大部分是绿色的,在第一次致命的霜冻中,至少有50％的植株仍在开花。植株和果实的产油量分别为1.22％和1.50％。由主要成分和次要成分反映的油的质量是用薄层-气液色谱法和质谱与红外线光谱法测定的。在整株油中鉴定出19种成分,在果实油中鉴定出14种,它们分别占油的96％和98％。反式茴香脑、葑酮、草蒿脑和 Horticultural traits and oil quality of annual live sweet anise in Ota were measured at three consecutive seasons in Alberta, Canada. Only the average growth and growth status of fennel under irrigation and fertilization was estimated. Umbels are largely green at harvest, with at least 50% of the plants still blooming in the first deadly frost. Plant and fruit yields were 1.22% and 1.50%, respectively. The quality of the oil as reflected by the major and minor components is determined by thin-layer gas-liquid chromatography and mass spectrometry and infrared spectroscopy. Nineteen components were identified in the whole oil and 14 in the fruit oil, accounting for 96% and 98% of the oil, respectively. Trans-anethole, ketones, Artemisia annua and
