Asymbiotic germination of Borneo endemic orchid vanda hastifera
Orchid seeds are tiny, extremely light and often referred as "dust seeds". The seeds produced in vast numbers and contain very small nutrient reserves (Arditti and Abd Karim, 2000). Seeds may germinate in nature but will not grow unless infected by mycorrhizal fungus, which supplies the yo...
