番茄是一种经济效益较高的蔬菜作物,在保护地和露地栽培中均占有重要的地位。但在生产上,经常发生番茄果实畸形(包括果实开裂、脐疤过大等)的问题,对经济效益有一定影响。我们结合多年的番茄引种和栽培研究,对番茄果实畸形的致畸因素作了初步探讨,并提出以下几条防治措施,请教于广大同行。 一、遗传因素 包括果型大小、果实形状和亲本因素。 (一)果型大小 传统文献认为大型果品种畸形较多,小型果品种畸形果较少。大型果常有较粗的花柱,形成较大的果脐,大到一定程度就有碍外观。若花柱呈扁形或其它不规则形状,则所结果实必为畸形。我们认为,果实性状的表达,包括畸形性状的表达,是受遗传基因控制的,可以通过个体选择加以改善。因为在一个很大的品种群体内,总有个别植株在相同条件下畸形果比较少或不发生畸形(以下称整齐果)。在这种思想指导下,作者早年曾从畸形
Tomato is a highly economical vegetable crop, both in protected and open field cultivation occupy an important position. However, in production, tomato fruit deformities (including fruit cracking, umbilical scar too large, etc.) often occur, the economic benefits have a certain impact. We combine many years of tomato introduction and cultivation of tomato deformity of teratogenic factors made a preliminary study and proposed the following prevention and treatment measures, consult the majority of peers. First, genetic factors include fruit size, fruit shape and parental factors. (A) the size of the fruit The traditional literature that large fruit deformity more small fruit deformity less fruit. Large fruit often thicker style, forming a large umbilicus, to a certain extent, hinder the appearance. If the style is flat or other irregular shape, the result will be deformed. We think that the expression of fruit traits, including the expression of abnormal traits, is genetically controlled and can be improved by individual selection. Because in a large breed population, there are always a few plants under the same conditions with less or no deformed deformity (hereinafter referred to as neat fruit). Under the guidance of this kind of thinking, the author has been deformed from the early years
