Yeasts in Hevea brasiliensis latex
Microbiology, 2016Yeast abundance and species diversity in the latex of caoutchouc tree Hevea brasiliensis (Willd. ex Juss.) M611. Arg., on its green leaves, and in soil below the plant Was studied. The yeasts present in the fresh latex in concentrations of up to 5.5 log(CFU/g) were almost exclusively represented by the species Candida heveicola, which was previously ...

Genomic technologies for Hevea breeding
2019The commercial production of high quality natural rubber (NR) solely depends on Hevea brasiliensis Muell. Arg, (Para rubber tree) and accounts for >98% of total production worldwide. NR with its unique properties is an essential commodity for the automobile industry and its synthetic counterparts are in no way substitute to it.

Natural cis-1 ,4-po1yisoprene occurs in over 2000 species of higher plants, the most well known of which is natural rubber from Hevea brasiliensis. Other plants, such as guayule (Parthenium argentatum), Russian dandelion (Taraxacum kok-saghyz), goldenrod (Solidago altissima), Jelutong (Dyera retusa), and fungal genera such as Lactarius volemus have ...

The genus Hevea is a member of the Euphorbiaceae and is endemic to the Amazon basin and its neighbouring parts including Matto Grosso, Upper Orinoco and the Guianas. The taxonomy of the genus has been intensively studied (29). Nine species are now recognized in the genus and of these only H. brasiliensis is important economically.

Hevea : micropropagation by somatic embryogenesis
1997The different steps of the process for maintained somatic embryogenesis were described. The current yields of the process were shown. They led to discuss on the limiting factors with the prospect of mass micropropagation. The first field trial with five, years old vitroplants was analysed. First conclusions were promising.

Mycologia, 1945
In December, 1943, an unknown disease characterized by a severe leaf spotting was found in a nursery of Hevea Spruceana at Turrialba, Costa Rica. Six weeks later, following a prolonged rainy period, this disease had reached epiphytotic proportions in the spruceana nursery where it was causing leaf, petiole, and twig blight, and also was producing minor

Rubber Chemistry and Technology, 1954
Abstract Phosphatides, together with other lipin substances, were extracted from fresh latex in the form believed to be that in which they naturally occur. Analysis, after removal of water-soluble impurities, gave evidence that the total lipin contained approximately 51 per cent lecithin, 10.5 per cent inositol phosphatide, 3 per cent ...

HEVEA-PRODUCTS AND POLYPROPYLENE
Herald of Technological UniversityThe main source of natural rubber is hevea, a genus of evergreen monoecious rubber-bearing trees. Natural rubber belongs to biodegradable polymers and does not accumulate in nature. In this regard, it can be used as a biodegradable additive for polypropylene, which is not biodegradable.
