Abstract

Pythium oligandrum was applied as tulip bulbs or gladiolus corms soak prior or after inoculation with formae speciales Fusarium oxysporum. The mycoparasite used before inoculation with pathogen suppressed the development of Fusarium rot. This effect was not observed, however, when P. oligandrum was used 24 hr after bulb inoculation. Soaking of forced tulip bulbs in oospore suspension of P. oligandrum may reduce Fusarium rot spread and increase number of flowers, but at conc. 2.5 x 10(3)-10(4)/cm3 caused inhibition of tulip root growth.

摘要

少孢节丛孢菌在接种尖孢镰刀菌专化型之前或之后，用作郁金香种球或唐菖蒲球茎的浸泡剂。在接种病原菌之前使用这种真菌寄生菌可抑制镰刀菌腐烂病的发展。然而，当在种球接种后24小时使用少孢节丛孢菌时，未观察到这种效果。将促成栽培的郁金香种球浸泡在少孢节丛孢菌的卵孢子悬浮液中，可能会减少镰刀菌腐烂病的传播并增加花朵数量，但在浓度为2.5×10³-10⁴/立方厘米时会抑制郁金香根系生长。
