Flowering Induction of Longan Trees ( Dimocarpus Longan Lour.) Grown in Sarawak
Flowering Induction of Longan Trees ( Dimocarpus longan Lour.) Grown In Sarawak by Lau Cheng Yuon Agriculture research Centre, Semongok. Tel: 062-611171 fax: 082-611178 E-mail: [email protected] Abstract. Under the tropical climate of Sarawak, Edaw longan trees can be induced to flower while flowering intensity of free-flowering Diamond longan can be improved by application of chemical agents such as potassium chlorate, sodium chlorate and 'Vita-min'. The use of sodium chlorate is recommended as it is easily available and the cheapest one to use. It can be applied as a soil drench at a rate of 15g per m2 canopy. The best time of application is when trees have shoots of mature leaves with sign of new flushes. With this technology, cultivation of longan especially the high quality Edaw cultivar in the State can be promoted and encouraged to cater for domestic demand. 1.Introduction. The longan ( Dimocarpus longan Lour.) is a sub-tropical fruit in the family Sapindaceae and is native to Southeast Asia. It is now primarily cultivated in China, Taiwan, Thailand, Vietnam as well as Queensland (Australia) and Florida and Hawaii (U.S.A). This fruit is considered one of the important economic fruit crops in South East Asia (Crane, 2000). Longan planting materials from Florida such as Kohala and Thailand such as Baidum, Biew kiew, Chompoo, Fortune eye. Diamond, Ping pong, Edaw and Ezami were acquired by ARC, Semongok in the mid-eighties and since the nineties respectively for planting and evaluation purposes. Local nurserymen started to import and promote planting of free flowering cultivars such as Diamond and Ping pong in the late nineties. -

I Is the Sunda-Sahul Floristic Exchange Ongoing?
Is the Sunda-Sahul floristic exchange ongoing? A study of distributions, functional traits, climate and landscape genomics to investigate the invasion in Australian rainforests By Jia-Yee Samantha Yap Bachelor of Biotechnology Hons. A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2018 Queensland Alliance for Agriculture and Food Innovation i Abstract Australian rainforests are of mixed biogeographical histories, resulting from the collision between Sahul (Australia) and Sunda shelves that led to extensive immigration of rainforest lineages with Sunda ancestry to Australia. Although comprehensive fossil records and molecular phylogenies distinguish between the Sunda and Sahul floristic elements, species distributions, functional traits or landscape dynamics have not been used to distinguish between the two elements in the Australian rainforest flora. The overall aim of this study was to investigate both Sunda and Sahul components in the Australian rainforest flora by (1) exploring their continental-wide distributional patterns and observing how functional characteristics and environmental preferences determine these patterns, (2) investigating continental-wide genomic diversities and distances of multiple species and measuring local species accumulation rates across multiple sites to observe whether past biotic exchange left detectable and consistent patterns in the rainforest flora, (3) coupling genomic data and species distribution models of lineages of known Sunda and Sahul ancestry to examine landscape-level dynamics and habitat preferences to relate to the impact of historical processes. First, the continental distributions of rainforest woody representatives that could be ascribed to Sahul (795 species) and Sunda origins (604 species) and their dispersal and persistence characteristics and key functional characteristics (leaf size, fruit size, wood density and maximum height at maturity) of were compared. -
