 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : The Role of Wild Banana (Musa acuminata Colla) on Wildlife Diversity in Mixed Deciduous Forest,Kanchanaburi Province, Western Thailand) ผู้เขียน: ดร.ดอกรัก มารอด, ศาสตราจารย์ ,  ปิยะ ภิญโญ, ดร.ประทีป ด้วงแค, รองศาสตราจารย์ , Tanaka Hiroshi สื่อสิ่งพิมพ์:pdf AbstractThe roles of wild banana (Musa acuminata) on wildlife diversity in mixed deciduous forest were studied at the Mae Klong Watershed Research Station, Kanchanaburi Province, Thailand during 2003-2004. Thirty wild banana individuals were selected and their phenomena were recorded every two weeks. The number of seeds and seed size of ripened fruit samples were counted and measured. The survival of wild banana seedlings was also recorded every month. Wildlife diversity and its relationships to wild banana phenomena were investigated by automatic camera and live traps. The remote automatic camera traps, eight per census, were set up for two nights and three days in places that wild bananas had flowered or fruited every month. Live-traps were also used at the same time with baited banana fruit inside and eight traps were placed near the banana clumps in every census. The results showed that there was a greater seedling survival of wild bananas from clones than from seeds. The establishment of wild banana was directly from colonized clumps, which showed high efficiency by rapidly occupying the complete disturbed area. Wild bananas flowered and fruited at different times among the culms through the year and facilitated good conditions for both forest regeneration and food resources to wildlife. The results on wildlife diversity showed that 17 species from 16 genera came to utilize the inflorescences, fruits and seeds of wild banana. The roles of wildlife on wild banana could be classified as 1) pollinator by the greater short-nosed fruit bat (Cynopterus sphinx), the streaked spiderhunter (Arachnothera magna) and the little spiderhunter (A. longirostra), 2) seed predator by Pallas’s squirrel (Callosciurus erythraeus), the gray-bellied squirrel (C. caniceps), the Indochinese ground squirrel (Menetes berdmorei, Rattus spp., Mus sp.) and the common treeshrew (Tupaia glis), and 3) seed disperser by the Asian palm civet (Paradoxurus hermaphroditus). Thus, considering the important roles of wild banana in mixed deciduous forest, it could be classified as a “keystone species”, which promotes forest regeneration and provides food resources to wildlife, especially during the dry season. |

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Micropropagation of Kluai Khai (Musa acuminata ‘Klaui Khai’) Using Sword Suckers and Inflorescences at Various Development Stages) ผู้เขียน:นางเบญจมาศ ศิลาย้อย, ศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractComparison the use of inflorescence at various stages of development versus meristem of sword suckers of Kluai Khai, as a source of the primary explants for in vitro culture was conducted . For shoot initiation, the explants were cultured on semi solid and liquid medium of Murashige and Skoog (1962) supplemented with 5 ppm. of 6-benzylaminopurine (BA). It was found that on liquid medium, the culture produced the first shoot faster than the ones on semi solid medium. The first shoot of suckers occurred on the 30th and 45th days after culturing on liquid medium, and semi solid medium respectively, while those at the 5th, 3thand 1st days of developmental stage occurred on the 52nd, 52nd and 56th days of culturing respectively. After 2 months, the sucker on liquid medium was noticed to give the shoot number of 1.88 shoots per explant, where as on semi solid medium, it yielded 0.6 shoot per explant. The shoot number of inflorescence at the 5th, 3rd and 1st days of developmental stage cultured on liquid medium were 2.08 (the highest), 1.93 and 1 shoots per explant respectively. At this stage, no development of the shoots on semisolid medium had been found to develop yet. Shoot multiplication was also revealed to be stimulated by transferring explants into semi solid medium, thus yielding such higher shoot number than the others. On the 5th month, the inflorescence at the 5th day of developmental stage gave the highest shoot number of 9.06 shoots per explant which was not significantly different from those of 8.9 shoots per explant at the 3rd day of developmental stage. The shoot number of the others were significantly lower different. 10% off-type shoots, occurred in inflorescence culture. After transplanting plantlets to the nursery, the survival rate was 96 percent. |
