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.

Taking Walla patta to the international communinty
Dr. Upul Subasinghe and his research team managed to take Walla patta (Gyrinops walla) to the international community through some scientific publications on the research findings. Up to now, two full papers were published in two reputed scientific journals and those can be viewed by the following links.
1. Title: "Agarwood type resin from Gyrinops walla: A new discovery"
2. Title "Agarwood resin production and resin quality of Gyrinops walla"
In addition to that Dr. Subasinghe presented a paper on "Agarwood resin production of Gyrinops walla" at the International Scientific Symposium held in the University Putra Malaysia from 4 to 7 September 2013. The abstract of that presentation is given below.
Gyrinops
walla, a member of the agarwood family
Thymelaeaceae is recorded in the wet zone of Sri Lanka has not been previously
studied to identify its ability of producing agarwood. Therefore the present
study was the first ever to conduct to identify the production of agarwood resins
in G. walla and its resin quality.
Three distinctive areas of the low country
wet zone of Sri Lanka were selected for this study and 22 G. walla trees were used for sample collection. Since there were no
artificial resin induction methods applied earlier, all selected trees had
natural wounds occurred sometime before the sample collection due to natural injuries.
The dark coloured tissues of the affected areas were collected without felling
the trees and the resins were extracted by a solvent extraction method. The
diameter and height of the sampled trees were measured and the geographical
positions were also recorded. The extracted resins were further analysed by
using gas chromatography technique to identify the different compounds and to compare
those compounds with that of selected Aquilaria
species.

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.

Dr. Upul Subasinghe was awarded SLR 11.6 million to conduct further research on Walla patta
Under the Public-Private-Partnership Programme of the National Research Council (NRC) of Sri Lanka, it has awarded SLR 11.6 million Dr. Upul Subasinghe for conducting further research on Walla patta (Gyrinops walla). Sadaharitha Plantations Limited jointly funds this three year research programme with the NRC.
The Public-Private-Partnership programme is a result of the budget proposals over the past few years to strengthen the economy by scientific and technological findings. Moreover, the present proposal, which was among the 6 selected ones for funding by the NRC over 60 applications, is in line with the Green Economy concept of the Sri Lanka Government.
It is expected to obtain the following information by conducting the proposed research project .
1. The seed germination methods
2. Most effective agarwood resin induction methods
3. Agarwood quantity and quality variations with tree size, age and climatic conditions
4. Optimum resin extraction methods
The findings will definitely contribute to the national economy of Sri Lanka by providing silvicultrual, chemical and technological information that are required for large and medium scale Walla patta plantation development in the country. In addition, the results will benefit the villagers living in the low country wet zone of Sri Lanka by providing the correct information on planting methods, resin formation and harvesting times of this precious tree currently exploited without having a proper knowledge on its value.
