3种Cavandish香蕉(3倍体芭蕉AAA)栽培品种Lacatan,Robusta和Valery果实自然伤口受香蕉炭疽病菌(Colletotrichum musae)和轴腐病菌感染后相互之间的感病性。青绿硬果实,在13℃温室下放置 2周,然后在20℃温度下用乙烯人工催熟,对潜伏的病害作出估计。在21℃温度下记录果实从成熟到产生斑点所需的天数。Robusta和Valery果实产生的轴腐病及成熟时产生的斑点比Lacatan严重。船运过程受伤,产生颈腐病和伤口炭疽病为任何潜在感病性的差异,这三个品种的表现相同。 四倍体香蕉(芭蕉AAAA)代号65—3405-1接种炭疽病菌,会对伤口炭疽病产生抗性;Lacatan接种后抗性中等,Valery和Gant Cavendish接种后抗性相同。
The natural wounds of three cultivars of Cavandish banana (AAA pollen AAA), Lacatan, Robusta and Valery, were susceptible to each other after being infected with Colletotrichum musae and rotifers. Green hardwood, placed in a greenhouse at 13 ℃ for 2 weeks, then artificial aging with ethylene at a temperature of 20 ℃ to make an estimate of the potential disease. Record the number of days it takes for the fruit to mature from maturing to spotting at 21 ° C. Shaft rot produced by Robusta and Valery fruits and blooms at maturity are more severe than Lacatan. The shipping process was injured, causing neck rot and wound anthracnose for any potential difference in susceptibility, the three breeds performed the same. Tetraploid banana (AAAA) code 65-3405-1 is resistant to anthracnose in wounds when inoculated with Colletotrichum gloeosporioides; moderately resistant after Lacatan inoculation, with the same resistance after inoculation with Valery and Gant Cavendish.
