为了对设施栽培黄瓜进行精准管理，利用皮尔逊相关和逐步回归分析了两个品系发育过程中环境因子与香气日增量的关系。与供试品系无关，挥发性化合物和C6醛的日增量与日均光强(X-1)呈正相关，而C9醛的日增量与日均相对湿度(X-4)和日间平均相对湿度(X-7)呈负相关。X-1是影响两个品系挥发性化合物日增量最显著的环境因子，X-7是对14-1号C9醛日增量影响最大的环境因子，X-1和X-4是26号对C6醛和C9醛日增量影响最大的环境因子。预测了一系列环境因素对挥发性化合物最大日增量的影响。
To provide precision management of cucumber under protected cultivation, the relationships between environmental factors and daily increment of aroma in two lines were analyzed during development, using Pearson correlation and stepwise regression. Irrespective of the line tested, the daily increment of volatile compounds and C6 aldehydes were positively correlated with average daily light intensity (X-1), while the daily increment of C9 aldehydes was negatively correlated with average daily relative humidity (X-4) and average daytime relative humidity (X-7). X-1 was considered as the most significant environmental factor which affected the daily increment of volatile compounds in both lines, X-7 was the environmental factor which affected the daily increment of C9 aldehydes most in No.14-1, and X-1 and X-4 were the factors which affected the daily increment of C6 aldehydes and C9 aldehydes most in No.26. A range of environmental factors was forecast for the maximal daily increment of volatile compounds.
