1选育经过1984年沈阳农业大学山植课题组与本溪县林业局、本溪市农委多种经营处共同对本溪市农家栽培的山植进行调查,当地栽培的山楂有山城1号、2号、牛心台1号、2号、思山岭等品种。1986—1990年调查比较了这些品种的树体、果实性状,确认其植物学特征一致,实为同一品种,当时统一命名为“偏岭山植”。1988—1992年进行了加工性状、贮藏性能试验、果实营养成分测试和生物学特性观察等。证明其果实鲜食与加工品质好,耐贮藏,树体生长健壮、丰产稳产、抗性强、适应性广,是适于本溪及与其气候相近地区栽培的优良山植品种。目前本溪地区已… 相似文献

The effects of nutrition on tomato fruit size and shape are summarized, based on the results of a factorial trial in heated glasshouse borders. The varieties grown were Potentate, J168 and Moneymaker.The average weight per fruit, calculated from total weights and numbers, was decreased by potassium and magnesium sulphates. Both high nitrogen (760–830 lb. N per acre) and low nitrogen (30–150 lb. N) decreased the weight per fruit as compared with the intermediate nitrogen level (300–380 lb. N). The weight per fruit of varieties J168 and Moneymaker, grown for two seasons, was decreased significantly by high phosphorus in one year and increased by lime in both years.The uniformly coloured and regularly shaped fruits were graded into four commercial-size categories. Expressed as percentages of the sum of these four grades, the proportion of large fruits showed nutritional responses generally similar to those for average weight per fruit, with opposing trends in the smaller size categories.The proportion of somewhat irregularly shaped fruit in the uniformly coloured categories, studied for six seasons, was appreciably affected by nutrition. Fruit shape was improved by high potassium and magnesium, and also by nitrogen deficiency. High phosphorus affected the shape adversely. Liming improved the shape of fruit of variety Potentate in three out of four seasons, but the opposite effect was found with J168 and Moneymaker in the final season.The relation of fruit size and shape to soil salinity is discussed. 相似文献

以6个苹果品种为试材,测定贮藏前与贮藏5个月后的果实硬度、可溶性固形物、可溶性总糖、可滴定酸、维生素C含量。结果表明,‘华红’贮藏前果实维生素C含量较高,贮藏后总酸与维生素C含量下降幅度较小,贮藏前后均具有较高的营养价值;‘澳洲青苹’贮藏前果实硬度、总酸、维生素C含量较高,贮藏后各营养指标下降幅度较小,有高酸、多汁的特性,生食品质中等,主要用作果汁加工;‘望山红’与‘寒富’贮藏前果实的营养成分含量高,味道纯正,但贮藏后总酸和维生素C含量下降明显,适宜鲜食;‘岳帅’与‘金冠’贮藏前果实硬度、总酸、维生素C含量较低,贮藏后硬度、总酸含量下降幅度大,适宜鲜食。 相似文献
