苹果果实硬度适宜测定部位的研究

Study on Stuitable Parts for Apple Firmness Determination

为确定苹果硬度适宜测定部位,测定了"红富士"、"秦冠"苹果果实顶部、果实阳面、果实阴面、果实肩部的硬度。结果表明:"红富士"、"秦冠"苹果的果实硬度均表现为果实顶部的最高,其次为果实肩部和果实阳面,果实阴面最低。虽然果实阳面、阴面的硬度平均值低于果实不同部位硬度的平均值,但该部位最易受到伤害,故苹果果实硬度测定部位为果实阳面、阴面,硬度值应取阳面、阴面硬度的平均值。

In order to determine a suitable parts for apple firmness determination,firmness of ＇Red Fuji＇ apple and ＇Qinguan＇ apple had been determined at fruit apex,fruit sunny side,fruit shade side and fruit shoulder.The results showed that the fruit firmness at fruit apex was the highest,fruit shoulder and fruit sunny side were followed,fruit shade side was the lowest of ＇Red Fuji＇ apple and ＇Qinguan＇ apple.Although the average firmness of fruit sunny side and fruit shade side were lower than the firmness of the average firmness in different parts of the fruit,however,fruit sunny side and fruit shade side were the most vulnerable parts of one fruit,so fruit sunny side and fruit shade side should be reasonable parts for apple fruit firmness determination,and the fruit firmness should be the average firmness of fruit sunny side and fruit shade side.
