比较分析了3个羽衣甘蓝品种（‘Toscano’、‘Redbor’、‘Winterbor’）在不同农作制度下的生理生化特性。在田间和温室系统中生长的植物中观察到高生物量产量，这可能是由于生长期间较高的光照强度（阳光）和较低的种植密度。最高的相对生长率观察到在该领域的'Redbor'（104毫克g-1d-1）和'Winterbor'羽衣甘蓝（115毫克g-1d-1），而最高的生长率'Toscano'羽衣甘蓝被发现在温室系统（109毫克g-1d-1）。对于所有三个品种，最小的生长速率（72 - 78 mg g-1 d-1）和最高的比叶面积（295 - 378 cm-2 g-1）的叶片中观察到的生长室环境。然而，浓度最高的植物化学物质（叶黄素，紫黄质，叶绿素，叶绿素b）检测羽衣甘蓝叶从生长室。在强光条件下（PPFD> 1000 μ mol m-2s-1），从田间和温室生长的羽衣甘蓝叶片中检测到黄斑色素玉米黄质。通过互作研究，确定了品种类型（基因型）、收获时的生育期和耕作制度是决定羽衣甘蓝营养品质的主要因素。
Comparative analysis of the physiological and biochemical characteristics of three kale cultivars (‘Toscano’, ‘Redbor’, and ‘Winterbor’) in different agricultural systems was performed. High biomass yield was observed in the plants grown in the field and greenhouse systems likely due to the higher light intensity (sunlight) and lower planting density during growth. The highest relative growth rate was observed in the field for ‘Redbor’ (104 mg g-1d-1) and ‘Winterbor’ kale (115 mg g-1d-1), while the highest growth rate for ‘Toscano’ kale was found in the greenhouse system (109 mg g-1d-1). For all three cultivars, the smallest growth rate (72 – 78 mg g-1d-1) and leaves with the highest specific-leaf area (295 – 378 cm2g-1) were observed in the growth chamber environment. However, the highest concentration of phytochemicals (lutein, violaxanthin, chlorophylla, and chlorophyllb) was detected in kale leaves from the growth chamber. The macular pigment, zeaxanthin, was detected in leaf samples harvested from the field and greenhouse grown kale primarily during high light conditions (PPFD > 1000 μmol m-2s-1). Based on interaction study, cultivar type (genotype), growth stage at harvest, and farming system were identified as primary factors that determine nutritional quality in kale.
