Conteúdo: |
The mean HCN-potential (HCN-p) of freshly collected seeds of Hevea brasiliensis is 104,8 umol HCN per g dry weight. More than 90% of the cyanogenic compound is stored in the endosperm. During seedling development under aseptic conditions HCN-p of the entire seedling decreases to 15% within 19 days. The cyanogenic compounds are metabolized during germination to form noncyanogenic substance. Leaves of Hevea pauciflora, H. benthamiana, H. pauciflora x H. bentamiana and H. spruceana contain both linamarin and (R)-lotaustralin, whereas lotaustralin was not detectable in leaves and seeds of H. brasiliensis. |
