Native Australian Acacias: Unrealised Ornamental Potential

Ratnayake,Kamani; Joyce,Daryl (Chronica Horticulturae, 2010-09)

Acacia, commonly known as wattle, is the largest genus of flowering plants in Australia. Over 950 species have been identified on the continent, constituting more than half of the 1352 species found worldwide (Maslin, ...
Development of a Jackfruit-Based Vegetarian Finger Enriched with Vegetable Protein

M.N.M. ASIF; M. BULATHKANDAGE; R.H.M.K. RATNAYAKE; K.H. SARANANDA (Proceedings of 17th Agricultural Research Symposium, 2018)

An attempt was made to develop a vegetarian finger (sausage) as a value added product from jackfruit. The protein content was enhanced by incorporating vegetable protein (VP) as mushroom and okara flour (by-product of ...
The Effect of Variety and Fertilizer Application on Functional Properties of ‘Mukunuwenna’ (Alternanthera sessilis)

Y.D.A. Jayawardana; K.H. Sarananda; S.M.A.C.U. Senarathne; R.H.M.K. Ratnayake (Journal of Food and Agriculture, 2018)
