安色疫霉在有利的天气条件下接种于胶果,致病快,产孢多,产孢持续时间长。而在不利的天气条件下接种,致病时间拉长,产孢期缩短。孢子囊能在胶果表面干燥的情况下形成,也能在胶果上的次生菌落上长出。少量的水就足以使孢子囊传播,而其中... 详细信息

安色疫霉在有利的天气条件下接种于胶果,致病快,产孢多,产孢持续时间长。而在不利的天气条件下接种,致病时间拉长,产孢期缩短。孢子囊能在胶果表面干燥的情况下形成,也能在胶果上的次生菌落上长出。少量的水就足以使孢子囊传播,而其中只有少数的孢子囊能够释放游动孢子。

橡胶树白粉病菌的生物学

世界热带农业信息 1987年第1期 19-25页

作者： a.de s.Liyanage 张开明

体外和活体研究表明,从病叶获得的橡胶树粉孢的分生孢子大部分都不发芽,除非通过震动除掉垂死的孢子。24时龄的分生孢子的发芽率最高。分生孢子在5—35℃之间都发芽,在25—30℃发芽率最高,在40℃受到完全抑制。撒在叶上的分生孢子其发... 详细信息

体外和活体研究表明,从病叶获得的橡胶树粉孢的分生孢子大部分都不发芽,除非通过震动除掉垂死的孢子。24时龄的分生孢子的发芽率最高。分生孢子在5—35℃之间都发芽,在25—30℃发芽率最高,在40℃受到完全抑制。撒在叶上的分生孢子其发芽和侵染有相似的模式。在相当大的湿度范围内都能发芽,但良好的侵染需要高湿。在高温下培育的孢子,在饱和湿度下发芽较好。干燥显著降低孢子的生活力。在呈雾状自由水的载玻片和叶面上分生孢子发芽和生长都良好。但是长时间浸沉在水中抑制发芽。在人工光照下比在黑暗下发芽更好。直射阳光和紫外光对孢子发芽有害,离体的孢子比附在叶上的孢子受害更明显。当用橡胶树粉孢的分生孢子接种对白粉病具有不同感病性的橡胶品系的9日龄叶片时,接种后6小时在感病品系和耐病品系上都看到吸附胞。耐病品系的分生孢子粳数目比感病品系的显著较少。在耐病品系的侵入点周围看到一种过敏性反应。组织病理学研究表明表皮细胞内的原生质内容被分解了。在颗粒状表皮细胞内含物中有时看到败育的吸器,但在大多数情况下未见败育吸器。在耐病品系受害表皮细胞下的栅栏细胞似乎受到不利的影响。讨论了气象参数对橡胶树粉孢发育的影响和橡胶品系对侵染的反应,及白粉病的流行病学和防治。

橡胶树是斯里兰卡重要的栽培作物之一,有多种经济上重要的病害危害。为方便起见,把其分成叶、茎枝、割面和根部四类。一、叶部病害1、白粉病(Oidium heveae)白粉病是由子囊菌橡胶粉孢霉引起的最常见的叶部病害。它侵害越冬后不久新长出... 详细信息

橡胶树是斯里兰卡重要的栽培作物之一,有多种经济上重要的病害危害。为方便起见,把其分成叶、茎枝、割面和根部四类。一、叶部病害1、白粉病(Oidium heveae)白粉病是由子囊菌橡胶粉孢霉引起的最常见的叶部病害。它侵害越冬后不久新长出的嫩叶,导致第二次落叶。病害的传播和严重程度取决于越冬模式、品系的感病性和换叶期的气候条件。

绪论巴西橡胶树是落叶树,成龄胶树一般都在每年年初落叶。老叶的这种自然脱落通常叫做越冬。相反,幼树可以在老叶脱落前长出几蓬新叶。这种落叶抽叶过程整年都有出现,没有一个显著的年周期。引起胶树叶片衰老和脱落的主要因素是生长促进物质吲哚乙酸和生长抑制物质脱落酸之间的不平衡。另一方面,随着叶龄增长,蛋白质、核糖核酸的合成受到抑制以及某些酶水解活动的增加也与此有关。
