摘要
在新建立的苹果园中推广许多具有抗病基因的罗马尼亚品种是可取的。这就是为什么我们认为对一些罗马尼亚苹果品种的评估很重要,这些品种的培养规模是理想的,因为它们对真菌白弧菌(Podosphera leucotricha)的攻击行为是对苹果最有害的病原体之一。品种评价于2019 - 2021年在Bistrita水果种植研究站(RSFG)的试验田进行,以6个罗马尼亚品种和5个外国品种为目标。在未处理的地块和采用常规处理方案的地块均进行了观察。结果突出了SCDP Bistriţa创造的品种:'Bistrițean'和'Starkprim',这些品种与'Starkrimson'一起,由于在三年的研究中没有白粉病症状而脱颖而出。已知对白粉病敏感的品种,“Idared”和“Jonathan”受影响最大,其次是“Golden Delicious”。品种‘Florina’、‘Generos’和‘Auriu de Bistrița’表现出中低灵敏度,而‘Aura’和‘Salva’表现出极低灵敏度。
THE RESPONSE OF SOME ROMANIAN AND FOREIGN APPLE CULTIVARS TO THE NATURAL INFECTIONS CAUSED BY PODOSPHERA LEUCOTRICHA, IN BISTRIȚA AREA
It is desirable that in the newly established apple orchards to be promoted as many Romanian cultivars that have genetic resistance to diseases. That is why we considered important the evaluation of some Romanian apple varieties whose expansion in culture is desired, in terms of their behaviour to the attack of the fungus Podosphera leucotricha, one of the most harmful pathogens that damage apples. The evaluation of the cultivars was performed in the period 2019 – 2021, in the experimental plots of Research Station for Fruit Growing (RSFG) Bistrita and targeted six Romanian cultivars and five foreign cultivars. Observations were made both in the untreated plots and in the plots where conventional treatment schemes were applied. The results highlight the varieties created at SCDP Bistriţa: 'Bistrițean' and 'Starkprim' which, together with 'Starkrimson', stood out due to the absence of powdery mildew symptoms in the three years of study.The cultivars known to be sensitive to powdery mildew, 'Idared' and 'Jonathan' were most affected, followed by 'Golden Delicious'. The cultivars 'Florina', 'Generos' and 'Auriu de Bistrița' showed a medium to low sensitivity and 'Aura' and 'Salva' very low sensitivity.
期刊介绍:
FRUIT GROWING RESEARCH is an international journal, which has been issued under the care of the Research Institute for Fruit Growing Pitesti, Romania. Fruit growing research is an annual journal aimed at disseminating significant research and original papers on genetic resources, breeding of deciduous fruit trees species; fruit sustainable technologies – environment protection; propagation, virology and tissue culture, postharvest, that can be of interest to a wide audience of plant scientists in all areas of fruit growing. An international Editorial Board advises the journal.
