在喀麦隆西部,比较了10个商业性栽培的油梨品种的生长发育性状。各品种的生长高度为5—7米,冠幅为6—8米。Hickson品种的平均单株产果量最高,9年累计>1000千克/株,气候条件对其产量影响相对较少。Booth8和Booth7的产量也高,且无大小年。I(?)zamna几乎不结果。Nabal和Hickson品种的果实最大,单果重差不多达500克。Hickson、Taylar和Z(?)tano品种最抗叶斑病,Cercospora Purpurea Nabal则非常敏感。Anahein是最早熟的品种,其次是Booth 7和Booth 8。在这几年中上面所描述的性状有一定的变化,对于所研究的性状,以Hickson的表现最好。
In western Cameroon, growth and development traits of 10 commercial pear cultivars were compared. The growth of all varieties of 5-7 meters in height, crown width of 6-8 meters. The average yield per plant of Hickson cultivars was the highest, with a total of more than 1000 kg / plant in nine years. The climatic conditions had relatively little impact on the yield. Booth8 and Booth7 also have high yields and no size year. I (?) Zamna almost no result. Nabal and Hickson varieties have the largest fruit weight, weighing as little as 500 grams. Hickson, Taylar and Z? Tano cultivars are the most resistant to leaf spot and Cercospora Purpurea Nabal is very sensitive. Anahein is the earliest breed, followed by Booth 7 and Booth 8. The traits described above have changed a bit over the years, and Hickson performed the best for the traits studied.
