背景：进行了两个独立的田间试验来研究(i)三种灌溉处理(ID0 = 1585 m(3) ha(-1)，作为对照；ID1 = 1015 m(3) ha(-1)；ID2 = 2180 m（3) ha(-1)）和（ii） 3个植物密度处理（PD0 = 5.56 m(-2)），作为对照；PD1 = 4.44株m(-2)；和PD2 = 7.41植物m(-2))对莳萝的产量、挥发油成分和感官品质的影响。结果在灌溉剂量（ID0）和密度（PD0）均为中间条件时，单株产量最高。挥发油的主要成分为-香菜烯、莳萝醚和-香菜烯。最高灌溉剂量（ID2）产生了大多数主要化合物的最高浓度：-茶树烯（每100克49.5毫克）、-茶树烯（每100克6.89毫克）和柠檬烯（每100克2.49毫克）。在最高植物密度（PD2）中也发现了类似的模式：-茶树烯（每100克71.0毫克），莳萝醚（每100克16.7毫克）和-茶树烯（每100克9.70毫克）。描述性感官分析有助于做出最终决定，ID2和PD0处理的莳萝植株感官质量最高。结论若要获得芳香和感官品质最高的莳萝样品，建议采用灌溉剂量ID2和种植密度PD2；然而，如果唯一的目标是生产大量的莳罗，最好的选择是ID0和PD0。(c) 2016年化学工业学会
BACKGROUNDTwo independent field experiments were carried out to investigate the influence of (i) three irrigation treatments (ID0 = 1585 m(3) ha(-1), considered as a control; ID1 = 1015 m(3) ha(-1); and ID2 = 2180 m(3) ha(-1)) and (ii) three plant density treatments (PD0 = 5.56 plants m(-2), considered as a control; PD1 = 4.44 plants m(-2); and PD2 = 7.41 plants m(-2)) on the production, volatile composition of essential oil, and sensory quality of dill.RESULTSThe highest plant yield was obtained with intermediate conditions of both irrigation dose (ID0) and plant density (PD0). The main compounds of the essential oil were -phellandrene, dill ether and -phellandrene. The highest irrigation dose (ID2) produced the highest concentrations of most of the main compounds: -phellandrene (49.5 mg per 100 g), -phellandrene (6.89 mg per 100 g) and limonene (2.49 mg per 100 g). A similar pattern was found for the highest plant density (PD2): -phellandrene (71.0 mg per 100 g), dill ether (16.7 mg per 100 g) and -phellandrene (9.70 mg per 100 g). The use of descriptive sensory analysis helped in reaching a final decision, and the dill plants with the highest sensory quality were those of the ID2 and PD0 treatments.CONCLUSIONThe final recommendation is to use the irrigation dose ID2 and the plant density PD2 if the objective is to produce dill samples with the highest aromatic and sensory quality; however, if the only objective is to produce high amounts of dill, the best options are ID0 and PD0.
