Durian seeds normally germinate in 7 to 8 days. 95% after 10 days. Trees from seeds can grow up to 2 metres after 3 yrs.
Small seeds will take longer time to germinate.
INFECTION
Wounded seeds will screte a mucous and are highly susceptible to oxidative browning. Soaking seeds in antioxidant and
then grown on charcoal containing media with 1.0mgl NNA (a napthalene acetic acid) or IAA (Indole-3-acetic acid) and 1.0mgl
Kenetin can resolve the problem. Organic manures or fertilisers should not be used as they are conducive to P.palmivora infection.
Seeds can be coated with fungicide to resolve such problem.
Durian seeds have short viability period. Seeds are unable to withstand chilling or freezing. If seeds are stored
at 36C degree viability is lost after 6 days.
STERILIZED SEEDS FOR PACKAGING & SHIPPING
Seeds are best thoroughly washed. The flesh and aril be completely removed with scroching pad and then wrapped in moist
tissue papers. My personal experience shown that D24 seeds germinates just within 2 days if humidity is maintained. 95% will
germinate after 3 days! See images above.
SUNLIGHT
Exposing seeds to direct sunlight would reduce viability within hours though germination is rapid and easily accomplished.
