在生长室实验中，通过无创伤的土壤侵染（SI）或通过茎穿刺（SP）用青枯早疫病菌接种易感和抗性马铃薯品种的植物，并保持在温暖和凉爽的制度（28/16和20/8 ℃）中。C日/夜，分别）。SP和温暖的处理增加了易感性。在低温条件下，接种SP的品种发生潜伏侵染，而接种SI的品种则不发生潜伏侵染;在高温条件下，接种SI的品种发生潜伏侵染（接种SP的品种均为感病品种）。在温室内对7个马铃薯品种和7个青枯菌菌株进行了析因试验，病害分级与田间结果一致。来自Solanuum phureja的抗性足以用于安第斯[南美洲]高地。对于比通常种植马铃薯的气候更温暖的气候，需要采取综合控制措施来控制该病。
In growth chamber experiments, plants of susceptible and resistant potato cultivars were inoculated with P. solanacearum by soil infestation without wounding (SI) or by stem puncture (SP) and maintained in warm and cool regimes (28/16 and 20/8.degree. C day/night, respectively). SP and warm treatments each increased susceptibility. Latent infection developed at cool temperatures in cultivars inoculated with SP, but not SI, and at warm temperatures with SI (those inoculated by SP were all rated susceptible). In a factorial experiment with plants of 7 potato cultivars and 7 P. solanacearum strains conducted in a screenhouse under warm conditions, disease ratings were consistent with field results. Resistance derived from Solanuum phureja was adequate for the Andean [South America] highlands. For warmer climates than those in which potatoes are usually grown, integrated control measures will be needed to control the disease.
