通过测定123份普通丝瓜种质资源PPO的活性，研究普通丝瓜果肉PPO活性的变异，筛选出低活性的普通丝瓜品种材料，并对福建省种植的普通丝瓜品种进行评价和筛选。结果表明，供试普通丝瓜品种 PPO活性变异很大，变异范围为0.008～3.176△OD420· min-1· g -1，变异系数为177.5％，筛选出低PPO活性的普通丝瓜品种26份作为普通丝瓜品质改良的重要资源加以利用；福建省栽培的普通丝瓜品种之间的 PPO活性差异较大，其中‘农福丝瓜801’和‘金美2号’2个品种PPO活性较低，品质较好。
通過測定123份普通絲瓜種質資源PPO的活性，研究普通絲瓜果肉PPO活性的變異，篩選齣低活性的普通絲瓜品種材料，併對福建省種植的普通絲瓜品種進行評價和篩選。結果錶明，供試普通絲瓜品種 PPO活性變異很大，變異範圍為0.008～3.176△OD420· min-1· g -1，變異繫數為177.5％，篩選齣低PPO活性的普通絲瓜品種26份作為普通絲瓜品質改良的重要資源加以利用；福建省栽培的普通絲瓜品種之間的 PPO活性差異較大，其中‘農福絲瓜801’和‘金美2號’2箇品種PPO活性較低，品質較好。

PPO activities of Luffacylindrica Roem from the germplasm collection were determined .Varieties that were low in PPO activity were selected .The results showed that the PPO activities were between 0.008 -3.176△OD420 ·min-1·g -1 with a high coefficient of variation of 177.5% .In the end ,26 low-activity varieties were chosen for potential quality improvements on luffa. There were significant variations on the PPO activity in 8 common luffas in Fujian .Among them ,Nongfu Luffa 801 and Jinmei 2 were low in PPO activity ,and at the same time ,exhibited desirable quality characteristics .
