viscin การใช้

• The seeds are coated with a sticky material called viscin.
• Biochemically, viscin is a complex adhesive mix containing cellulosic strands and mucopolysaccharides.
• Some viscin remains on the seed and when it touches a stem, it sticks tenaciously.
• The viscin soon hardens and attaches the seed firmly to its future host, where it germinates and its haustorium penetrates the sound bark.
• A pollinium is a waxy mass of pollen grains held together by the glue-like alkaloid viscin, containing both cellulosic strands and mucopolysaccharides.
• Under the outer coat of the fruit is a sticky layer of viscin, which is rich in glucose, and which envelops the seed.
