Walla patta seed germination trials - A success after many attempts
After two unsuccessful attempts, Dr. Upul Subasinghe and his team managed to germinate Walla patta seeds under the nursery conditions. The initial attempts were failed due to the use of poor quality seeds collected from the mother trees and medium used which was not very much supportive for the germination of the seeds. Although still the germination rate is below 10%, the last attempt was considered as successful because these results lead to the next set of trials of germination rate enhancement. The germinated seedlings were transferred to the poly-pots of seedling medium and were kept inside the nursery. With the upcoming rains, those seedlings will be used for plantation established and different planting models will be tested in those trials.
The following pictures show the germination beds and the seedlings raised.
14,000 kg of smuggled Walla patta caught in Sri Lanka worth of US$ 1.6 Million - The value is a lie
In last may, all Sri Lanka media had a hit news in catching 14,000 kg of smuggled Walla patta scientifically known as Gyrinops walla by the Police and the Special Task Force. The price was given as US$ 1.6 million. According to the images showed in the electronic media, those tree samples appeared to be white, which means, there was no or very little agarwood formed in the trees. According to the experiments conducted by Dr. Upul Subasinghe and his team from 2010, about 95% wild-grown Walla patta trees do not produce Agarwood resins. Even if the resin is formed, it is due to natural reasons and therefore it does not evenly spread in the stem.
On the 31st of the same month, China Custom's Department has caught 8.145 kg of Agarwood formed in Aquilaria sinensis trees and the images shown below contain the real "Black Colour" Agarwood. According to the China Custom's sources, those Agarwood pieces are Class II in quality and even not Class I.
Therefore the person or persons valued the smuggled Sri Lankan Walla patta trees as US$ 1,143 per kilo has made another crime by lying to the public and showing the lack of knowledge in the trade. Further, this type of irresponsible behaviour leads to destroy the valuable Walla patta resource in Sri Lanka.
The Agarwood resins have to be artificially formed in the correct size of trees and in the next 6 to 12 month of time, Dr. Upul Subasinghe and his team will be able to come up with the best methods of forming resins in Walla patta under the research grant awarded to them worth about US$ 93,000 by the Government and the Private Sector.

First every study on Agarwood resin quality of Walla patta
The first ever research publication to compere the Agarwood production ability and Agarwood quality of Gyrinops walla (Walla patta) was done by Dr. Upul Subasinghe and his colleague Mr. Dhanushka Hettiarachchi in the Journal of Tropical Forestry and Environment in October 2011. The full article is available in the following link.

The abstract is given below
Agarwood is an expensive resinous product extracted from some members of Aquilaria andGyrinops species of the family Thymalaeaceae. Agarwood essential oil is a highly valued perfumery product in modern cosmetics and traditional Attar. Agarwood extraction from the above species and product manufacturing are done in India and Southeast Asian countries. However, over harvesting, low natural regeneration, and legal restrictions at present, have limited the supply of this product. Gyrinops walla is recorded in the wet zone of Sri Lanka, and it had been very rarely recorded in extreme Southwest India. However, recent reports of the abundance of G. walla in India are hard to find. Studies were not conducted in the past for G. walla on its ability of agarwood resin production and the quality of that resin. This study is the first to identify the agarwood resin formation and the quality of G. walla which can be used as a substitute for that of Aquilaria and other species of Gyrinops. Resinous tissues were extracted from six G. walla trees for the present study from two different areas, i.e., Labugama and Yagirala of the wet zone of Sri Lanka. The resins were solvent extracted in the laboratory and the resin quality was tested using gas chromatography analysis. The results indicated an extreme similarity of the compounds of G. walla resin with that of commercially available agarwood resins. However, further studies should be conducted to identify G. walla distribution and formation of agarwood.
