摘要：

为明确南方桃果肉褐斑症高效防控路径，开展桃流胶病与桃果肉褐斑症相关性调查。采集‘锦绣黄桃’、‘鹰嘴桃’流胶病轻重不一桃园、植株、主枝和同一植株流胶严重发生前与后果实样品，逐样逐果去皮观测褐斑症斑点发生程度，统计分析果实发生率、病情指数、呈色系数差异。结果表明，流胶重桃园果实发生率、病情指数、呈色系数分别比流胶中桃园提高20.35个百分点、0.2421、0.3760，相当于不流胶桃园的14.75、86.19、61.32倍；不流胶3年生植株分别仅为流胶重8年生植株的8.97%、2.32%、6.62%和流胶中植株的11.37%、3.41%、11.01%；流胶重的主枝分别较不流胶主枝提高39.18个百分点、0.0940和0.0884；3年生植株大量流胶后，其果实发生率、病情指数、呈色系数分别相当于大量流胶前的13.44、35.56、9.75倍。桃流胶可能是导致南方桃果肉褐斑症严重发生的主要诱因之一，应以控制桃流胶病严重发生蔓延作为重要防控途径。

Abstract:

In order to clarify the efficient prevention and control path of brown spot of peach pulp in southern China, the correlation between peach gummosis and brown spot of peach pulp was investigated. Fruit samples were collected from peach orchards, plants, and main branches with different severity of gummosis, and the same plant before and after the serious occurrence of gummosis in ‘Jinxiu yellow peach’ and ‘Olecranon peach’. The occurrence degree of brown spot was observed by peel removal, and the differences of fruit incidence, disease index and coloration coefficient were statistically analyzed. The results showed that the fruit incidence, disease index and coloration coefficient of peach orchards with heavy gummosis were 20.35 percentage points, 0.2421 and 0.3760 higher than those of peach orchards with moderate gummosis, which were 14.75, 86.19 and 61.32 times higher than those of peach orchards without gummosis, respectively. The 3-year-old plants without gummosis were only 8.97%, 2.32%, 6.62% of the 8-year-old plants with heavy gummosis and 11.37%, 3.41%, 11.01% of the plants with medium gummosis. The main branches with heavy gummosis increased by 39.18 percentage points, 0.0940 and 0.0884, respectively, compared with the main branches without gummosis. After a large amount of gummosis, the 3-year-old plants were equivalent to 13.44, 35.56 and 9.75 times of those before a large amount of gummosis. Peach gummosis may be one of the main inducements leading to the serious occurrence of brown spot of peach pulp in South China. The prevention and control strategy should be controlling the serious occurrence and spread of peach gummosis.
