Title: Comparative floral ontogeny of Hydrobryum loeicum, Hy. tardhuangense and Hanseniella heterophylla (Podostemaceae) Authors: Werukamkul, Petcharat; Ampornpan, La-aw Abstract: In order to elucidate the floral ontogeny of certain Thai species of the subfamily Podostemoideae, the flowering shoots of Hanseniella heterophy/la, Hydrobryum loeicum and Hy. tardhuangense were observed using scanning electron microscope. In all species studied. the flowering shoots protrude from the cavities where the tufted leaves arise on the crustose root. Mostly, the two outer bracts are leaf-like interpreting that the flowering shoots are converted from the vegetative shoots. In Hanseniel/a, bracts in the early developmental stage are similar shapes but different sizes arranging in 4 rows. In the mid-stage, the ventral bracts differentiate into normally 2 lobes, occasionally 3 lobes whereas the dorsal bracts develop into long deltoid shape. In Hydrobryum, the arrangement of bracts is distichous. The spathellas in all species initiate from tissue surrounding the floral meristem. Prior to the fusion of ventral and dorsal apical margins, the spathella apices become a triangle space in Hanseniella, narrow long space in Hy. loeicum and two-lipped in Hy. tardhuangense; and the floral organs are initiated inside the spathella. The two tepal primordia, the primary androecial primordium and the gynoecial primordium are initiated simultaneously. The two stamen primordia are differentiated from the primary androcial primordium when the gynoecium changes into a cylindrical shape and two carpel primordia are initiated. These dramatic ontogenetic changes and heterochronic shifts in the initiation of floral organs are highly specialized and very distinct floral development which have not found in any families of flowering plants.

Title: The innovation construction for the toughness measurement of rice kernel with the inner pressure method Authors: Kanthang, Paisan; Nicomrat, Duongruitai; Ritthong, Wirote Abstract: During the rice processing, the possible situations of rice kernel cracking and breakage are commonly occurred and these consequences cause a low marketing price. According to this issue, the real-time observation and together with the knowledge base of mechanical properties should be essentially helpful in detection of these defect observations. The objective of this work was established to study the mechanical stress-strain properties of rice kernels via our in-house pneumatic system design. We found that stress-strain of RD6, RD15, Phitsanulok 2 and Khao Dawk Mali 105 were greater than Khao'Yipun DOAI with moisture content of 20% w.b. These results tentatively indicated the mechanical stress-strains occurred were from the difference of rice shapes. Moreover, we could recognize that the characteristics of these various shapes significantly followed the scaling law of the relation between strain and time. We also found that the breaking force was different value for rice varieties. This parameter obtained can be such a high potential approach that can be used for further developing in the quantitative classification of rice varieties.

Title: Species diversity and reproductive phenology of Podostemaceae in Na Hahaeo District, Loei Province, Northeastern Thailand. Authors: Werukamkul, Petcharat; Ampornpan, La-aw Abstract: The species composition of Podostemaceae was studied in Loei, northeastern Thailand from November 2009 to July 2010 by extensive surveying in the rapids and waterfalls inside and outside of national parks, wildlife sanctuaries and protected areas. The samples collected are classified into 2 subfamilies, which are Tristichoideae and Podostemoideae. The former contains 2 genera and 3 species, Dalzellia kailarsenii, Terniopsis sp. 1, Terniopsis sp. 2. The latter has 4 genera and 9 species, Hanseniella heterophylla, Hydrobryum japonicum, Hydrobryum loeicum, Hydrobryum tardhuangense, Hydrobryum vientianense, Hydrobryum sp. 1, Hydrobryum sp. 2, Polypleurum sessile, Thawatchaia trilobata. The highest number of species occurs in Hydrobryum with 6 species following by Terniopsis with 2 species. The other four genera have one species each. Based on morphological and molecular analyses revealed that 2 species of the genus Hydrobryum are new and 2 taxa of Terniopsis are also new species. Polypleurum sessile and Thawatchaia trilobata are new recorded in Loei province. The result from this study indicates that the genus richness is relatively high in Loei province which encompasses 60% of the total number of genera (10) in Thailand. The plants in vegetative phase are completely submersed in swiftly running water during a warm wet season (May-October). The plants flower and set fruits and seeds when exposing to air during water level drop in a cool dry season (November- February). Description: รายงานการวิจัย--มหาวิทยาลัยเทคโนโลยีราชมงคลพระนคร,2553
