摘要

实验研究了用内生真菌Serendipita indica(前身为Piriformospora indica)接种杜鹃花“Nova Zembla”和“Alfred”小切口和幼株的后果。体外生根阶段的接种降低了体外根冠质量,但在温室中在未施肥的泥炭基质中种植微型植物后,与未接种的微型植物相比,植物长高33%,叶片多10%,根系更丰富。与未接种的植物相比,在体外生根、在泥炭基质中的温室中驯化并在移植到花盆时接种S.indica的年轻植物在15个月后表现出茎长增加35%和13%(取决于栽培品种)、叶数增加47%和叶绿素含量增加31%。S。杜鹃幼株上的籼稻表明其在该植物的苗圃生产中具有实际应用的可能性。

Stimulation of ex vitro growth of Rhododendron hybrids ‘Nova Zembla’ and ‘Alfred’ by inoculation of roots with Serendipita indica
Experiments were carried out to study the consequences of inoculating Rhododendron ‘Nova Zembla’ and ‘Alfred’ microcuttings and young plants with Serendipita indica (formerly Piriformospora indica), an endophytic fungus. The inoculation at the in vitro rooting stage decreased the in vitro root and shoot quality, but after planting microplants in a greenhouse in a non-fertilised peat substrate, the plants grew 33% taller, with 10% more leaves and with more abundant roots in comparison with the non-inoculated microplants. The young plants rooted in vitro, acclimated in a greenhouse in a peat substrate and inoculated with S. indica at the time of the transplantation to the pots displayed, after 15 months, an increase in the shoot lengths by 35% and 13%, depending on the cultivar, in the leaf number by 47% and in the chlorophyll content by 31% when compared with the non-inoculated plants. The beneficial effect of S. indica on the young Rhododendron plants indicates the possibility of its practical use in the nursery production of this plant.
