1. Cause

Phalaenopsis belongs to Angiospermae, asparagus, Orchidaceae and butterfly genus. As an angiosperm, Phalaenopsis must have seeds. However, because they need specific insect pollination to produce seeds, they are generally cultured artificially

And the seeds of Phalaenopsis, like other orchid plants, have no endosperm and are difficult to germinate. They must be infected by a specific fungus to provide nutrition and form a symbiotic relationship

2. Seed reproduction

There are two main methods of seed reproduction. One is natural sowing method, which is to sow the seeds in the flowerpot of the parent plant, and add the symbiotic bacteria required for seed germination; The second is aseptic seeding method, which immerses the mature capsule in 75-90% ethanol or chloroform solution for 2-3 seconds, then uses 5-10% bleaching powder solution to immerse for 5-20 minutes, repeats it once, conserves it on the culture medium, and puts it into the basin when patting and tasting 2-3 leaves
