Chromosome numbers and other karyological data of four Stemona species (Stemonaceae) from Thailand Naturalis
Hartl, M.; Kiehn, M..
Chromosome numbers and other karyological data of four Stemona spp. (Stemonaceae) from Thailand are reported. Three taxa (S. collinsae Craib, S. kerrii Craib and an unidentified species) exhibit 2n = 14 chromosomes, for S. curtisii Hook.f. a range of 2n = 13–16 was established. Based on the counts of c. 30% of the species of Stemona, x = 7 is very likely to be the basic number for the genus. Chromosome size and morphology of the investigated species are compared with literature data and show differences that might be of importance for infrageneric classification. In this connection the taxonomic position of the genus Pentastemona from Sumatra is also discussed.

Cryptophaea, a new euphaeid genus and three new species of Caloptera damselflies from Thailand (Odonata: Euphaeidae, Calopterygidae) Naturalis
Hämäläinen, M..
The euphaeid specimens from Doi Suthep (North Thailand) identified and redescribed by Asahina in 1987 as Schmidtiphaea schmidi are not conspecific with the holotype of S. schmidi Asahina, 1978, from Manipur (North-east India), but represent a distinct new species described as Cryptophaea saukra gen. & spec. nov. Bayadera vietnamensis van Tol & Rozendaal, 1995 and Schmidtiphaea yunnanensis Davies & Yang, 1996, are transferred to the genus Cryptophaea gen. nov. Anisopleura trulla spec. nov. from South Thailand is described and “Caliphaea confusa sensu Asahina, 1985“ from Doi Inthanon (North Thailand) is described as C. angka spec. nov.

Derris solorioides (Fabaceae), a new limestone species with true-paniculate inflorescences from North-Central Thailand Naturalis
Sirichamorn, Y.; Adema, F.A.C.B.; Welzen, P.C. van.
Derris solorioides is described as a new species and illustrated. This species is only the second calciphilous and true-paniculate species of Derris ever recorded. The species was found in isolated and protected limestone areas surrounded by agricultural areas in Nakhon Sawan province, North-Central Thailand. It is characterized by its rather smaller flowers but with more ovules than other species of Derris, and 1-winged pods showing a dark-coloured pericarp around the seeds without thickening of the pericarp. The characters of the pods are similar to those found in Solori, a genus once synonymized with Derris and, therefore, the epithet ‘solorioides’ was assigned. This species appeared to be a distinct taxon in the molecular phylogeny, separate from its...

Economic gains of improving soil fertility and water holding capacity with clay application: the impact of soil remediation research in northeast Thailand AgEcon
Saleth, Rathinasamy Maria; Inocencio, Arlene; Noble, Andrew D.; Ruaysoongnern, Sawaeng.
Declining productivity of agricultural soils in Northeast Thailand is a challenge facing land managers and farmers. A program was initiated in 2002 to investigate the potential role of incorporating clay-based materials into degraded soils as a means of enhancing productivity. This research report attempts to provide an ex-post assessment of the field level impact and economic viability of this approach, using the empirically derived estimates of the average income impacts that the application of bentonite or clay technology has generated among farm communities in Northeast Thailand. From an exclusive IWMI perspective, the impact evaluation suggests that the program has a net present value (NPV) of US$0.41 million with a benefit-cost ratio (BCR) of 2.44...

Effects of shoot pruning and inflorescence thinning on plant growth, yield and fruit quality of greenhouse tomatoes in a tropical climate JARTS
Max, Johannes Franz Josef; Schmidt, Lilian; Mutwiwa, Urbanus N.; Kahlen, Katrin.
The combined effects of shoot pruning (one or two stems) and inflorescence thinning (five or ten flowers per inflorescence) on greenhouse tomato yield and fruit quality were studied during the dry season (DS) and rainy season (RS) in Central Thailand. Poor fruit set, development of undersized (mostly parthenocarpic) fruits, as well as the physiological disorders blossom-end rot (BER) and fruit cracking (FC) turned out to be the prevailing causes deteriorating fruit yield and quality. The proportion of marketable fruits was less than 10% in the RS and around 65% in the DS. In both seasons, total yield was significantly increased when plants were cultivated with two stems, resulting in higher marketable yields only in the DS. While the fraction of undersized...

Forecasting with X-12-ARIMA: International tourist arrivals to India and Thailand AgEcon
Balogh, Peter; Kovacs, Sandor; Chaiboonsri, Chukiat; Chaitip, Prasert.
Forecasting is an essential analytical tool in tourism policy and planning. This paper focuses on forecasting methods based on X-12-ARIMA seasonal adjustment and this method was developed by the Census Bureau in the United States. It has been continually improved since the 1960s, and it is used by many statistics agencies and central banks. The secondary data were used to produce forecasts of international tourist arrivals to India for 2007-2010 and also these data were used to produce forecasts of international tourist arrivals to Thailand for 2006-2010. From these period the results confirm that the best forecasting method based on the X-12-ARIMA seasonal adjustment is X-12-ARIMA(0,1,2)(0,1,1), X-12-ARIMA(0,1,1)(0,1,1) and X-12-ARIMA(2,1,0)(0,1,1) for...

Fruit fly in Malaysia and Thailand 1985-1993 AgEcon
Collins, B.A.; Collins, David J..
Fruit flies are a serious economic pest affecting horticultural production world-wide. Increasing coordination of activities between neighbouring countries and those countries involved in fresh fruit trade is leading to more effective regional management of the fruit fly pest. 1.1 ACIAR Research Projects. ACIAR has supported fruit fly research in developing countries since 1984. Two projects, based in Thailand and Malaysia, have generated significant scientific and economic outcomes. The total cost of these two projects was $1.7m (in 1996 dollars). Specific outcomes include: 1. A more detailed understanding of exotic fruit fly species, their host range, pest status and spatial distribution; 2. Increased interest in fruit fly management in Thailand and...
