据报道,我国目前草莓病毒和类病毒已超过28种,一般减产3～5倍。在复合感染时损失更严重,除减产严重外,果实品质降低,果个变小,畸形果多,葡萄茎抽生量减少,生长势减弱。“塞久亚”系经中国无病种苗生产技术发展产业协会,用生物工程技术(茎尖分生组织培养法)培育的唯一脱毒草莓品种,经笔者栽培扩繁证明:植株根强苗壮,繁殖力强,成熟期大致与“全明星”相同,为中熟品种,极丰产,露地栽培至少获得1500～2000公斤。
According to reports, China’s current strawberry virus and the virus has more than 28 species, the general reduction of 3 to 5 times. In compound infection, the loss is more serious, in addition to the serious reduction in yield, the fruit quality is reduced, the fruit becomes smaller, the deformity is more, the number of grape stems is reduced and the growth potential is weakened. “Sejoya” by the Chinese disease-free seedling production technology development Industry Association, using bio-engineering technology (stem apical meristem culture) to cultivate the only detoxification strawberry varieties, the author cultivated propagation proved: plant root and seedlings Strong, fertile, mature roughly the same as “All-Star”, for medium-maturing varieties, very high yield, open-planted cultivation of at least 1500 to 2000 kg.
