Abstract

This research has been conducted to cooperate with the dry storage that has been presened previously. Electrical heaters were used in the previous research (Dry Storage) which is unsuitable for rural areas and rather expensive. The main purpose of this research is aimed at adaptation of wastes from industries and agricultural products to be used as fuels in appropriate stoves. Four types of stoves were disigned and two of them selected for this research. The 4 stoves give almost the same result. The second and the third types are rather complicate in construction and costly; heat loss is also high. Stove no. 1 and 2 have been selected for this research. The test results show that liverated heat from these two stoves is much greater than required. In some tests the steel grids even melted.

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Effect of CO2 and Termperature on Postharvest Quality Changes of Broccoli)

ผู้เขียน:ImgS. Phuchai, ImgS. Ketsa, ImgKosiyachinda

สื่อสิ่งพิมพ์:pdf

Abstract

Chiang Mai-grown broccoli was bought and shipped to Bangkok by truck within 30 hours. Broccoli was stored at 3 temperatures; room temperature (31 C) 1 and 4C under the following conditions: plastic basket, unsealed plastic bag and sealed plastic bag without and with adding 10% Co2. Storage life of broccoli held in sealed plastic bags with initial 10% Co2 at 1 and 4C could be extended up to 28 days and broccoli still remained green and fresh like newly harvested vegetable and it could be stored further. It is therefore strongly recommended that broccoli be stored at 4-5C in plastic bags with initial 10% CO2

ผู้เขียน:Imgนายนิวัติ เรืองพานิช, ศาสตราจารย์, ImgVanchai Viranant

สื่อสิ่งพิมพ์:pdf

Abstract

The change of land use practices from the hill evergreen forest to other land use types deteriorated the physical properties of soil. The bulk density of the top soil, 0 - 50 cm in depths was increased and soil porosity was decreased especially in the shifting cultivation and agroculture areas, but there was no difference at the depth of 50 - 100 cm in all types of land use. The amount of organic matter and sulfer in the soil was decreased in all types of land use except in the agroculture area that the amount of sulfur was increased due to the use of chemical fertilizers. In all types of land use, the organic matter content decreased with increasing soil depth, but in the contrary, the amount of sulfur increased with increasing soil depth. The pH was slightly increased in all depths and types of land use. The amount of phosphorus, potassium and magnesium was increased and mostly accumulated at the top soil and decreased with increasing soil depth. However, the amount of phosphorus was increased in agroculture and forest plantation areas and decreased in areas of shifting cultivation and enrichment planting. The potassium and magnesium content were highest in forest plantation areas and lowest in the hill evergreen forest, while the amount of calcium was highest in agroculture area and lowest in the hill evergreen forest. All of the phenomena mentioned above may be due to the influence of fire and chemical treatments. It was revealed that the change of the hill evergreen forest to other land use practices would impact the balance of nutrients in the system as well as the amount and rate of nutrient cycling. Most of the nutrients were moved and accumulated in the soil instead of storing in the form of plant biomass, Therefore, if the land were not properly used, the nutrients could be easily leached and lost from the system.

Abstract

Two experiments were conducted in order to get an appropriate technique for branding Pla Duk Dan (Clarias batrachus Linn.) with the criteria based on growth, survival and percentage of fish showing mark identification. The first experiment, two types of instruments were used, electrical hot-wire branding instrument developed by Moav et al. (1960 b) and cold branding instrument to compare their effectiveness. The fish were branded about midway of body depth at 2 positions1,~ ofb ody length from head and 31 from tail. The results showed that branding with these instruments at two different positions had no effect on mortality of the fish. Fish branded by electrical hot-wire at the latter position showed longest identification period (90% identified fish after 6 weeks of branding). 1 The hot-wire branding instrument should therefore be used for branding at the position o f 3 of body length from tail. The second experiment was made to evaluate the effect of hot-wire branding on growth and survival rates of Pla Duk Dan and the period of such branding mark identification. Pla Duk Dan of 25.79 5 86.5 cm long, 119.51 2 86.21 g. in body weight were branded by using electrical hot-wire branding instrument at about midway of body depth and at the position1~ obf ody length from tail. Sixty, 120,180 and 240 days after branding revealed that growth and survival rates of the branded fish were as the same as the controlled group. After 180 days of branding, 93.87% of the branded fish still showed mark identification, and at 240 days after branding 69.38% fish still showed those mark.

Abstract

Sixteen stray dogs were castrated (Hemicastration). The testis and epididymis were examined in order to investigate the normal conditions under the light microscopy. After these dogs were healthy, they were injected with a single dose of a-chlorohydrin (3-chloropropane-1, 2-diol) 100 mglkg b.w. subcutaneously. Testis and epididymis of each couple of the sixteen dogs were removed at different times following the injection-1, 2 and 3 days; 1, 2 and 4 weeks; 2 and 3 months, respectively. The histopathological lesions revealed that the epithelial cells of the seminiferous tubules and the initial segment of epididymis were damaged and degenerated after 1 day of treatment. Tremendous degeneration was observed at 3 days. However, the regeneration of the epithelial cells occurred within 1 week and appeared to be normal phenomena in all dogs after 1 week to 3 months of the experiment. By this preliminary investigation, a single dose of 100 mglkg body wt. of a-chlorohydrin injected subcutaneously had shown to be a temporary inhibition of spermatogenesis.

Abstract

Tioga strawberries of 4 different-colored stages were harvested from Intonon area in the cooler month of December. 1982. Their quality criteria were determined right after sorting at the lntanon Station. The remaining berries were air-shipped to lab in Bangkok for study at daily interval. Another batch of different stages of berries similar to the December crop was studied in the warmer month of March, 1983. It was found that after harvest all strawberries developed color rapidly. those of 21 -40% red color when harvested deloped color to an acceptable condition of over 90%) color within 2 days. The March crop had a slightly faster rate of color development, it is faster than the December crop by approximately half a day. More advanced stage of strawberries. the 61-80% colerl in the December harvest had higher SS than others by only 1 .O'%. Those of March had slightly lower SS than the December by about 0.5% The younger stage of 0-20% color strawberries tended to have higher acid content than other stages in the cooler month crop. Their difference in this respect between the two months was less than 0.0:3% in favor of the hotter month. The SS/ TA ratios of the cooler month strawberries are higher than those of the warmer month by lo;. It is suggested along the support of organoleptic evaluation that strawberries of above 41% color of either months possessed acceptable eating quality right after harvest. The younger stage of 21-40% color needed 3 days after harvest to attain such quality. Strawberries are firmer in the younger stages. They also had greater firmness in the cool month crop. Four days after harvest fruit firmness of the cool and hot month crops was different by 0.55 to 0.86 kg/cm2. Weight losses increased in relation with time. On the third day after harvest. the losses amounted to 6% for the December crop. while that for the warmer month was 9%. The apparent losses were fruit losses due to mechanical and biological injuries. The former factor played a bigger role due to human problems which could be alleviated with "Tender Loving Care" practices.

Abstract

Effect of seed maturity on field corn seed quality was studied at the National Corn and Sorghum Research Center, Nakhonrajasima province during July to November of 1979 and 1980. In order to obtain cprn seeds of thirteen different maturities, Suwan 1 variety was planted in 1979. At harvest, seed moisture content and a 100 seeds-weight were recorded. These seeds were dried to approximately 12% moisture content and stored in cold storage for the 1980 evaluation. As seed developmental stage proceeded, its moisture content decreased gradually to a value of 31.1% at physiological maturity stage. Seed weight, on the contrary, increased with seed developmental stage and reached the maximum during physiological maturity stage. The 1980 trial showed that germination and seedling vigor were increased with increasing maturity of seed being used. A satisfactory level of seed germination and seedling vigor was observed only when seed Age of 33 days after silking or older were used.

Abstract

Nine chemicals, including five antibiotics: Agrimycin, Aureomycin, Septrin-S, Streptomycin, and Terramycin; and four fungicides : Coppercide, Copper sandoz, Cuprosan super D, and Trimitox forte were tested to evaluate inhibition effect on the growth of Pseudomonas sp., the causal bacterial rot disease of orchids, by Petridish zonal inhibition. The result indicated Septrin-S was the most effective. The bacteria was also inhibited by Aureomycin, Streptomycin, Trimitox forte and Terramycin, respectively. Aureomycin at 500 ppm and Terramycin at 1,000 ppm provided a good protection of bacterial infection in the green house.

Abstract

Seven treatments of fertilizer and organic waste materiats (OWM) namely rice straw compost (RSC), activated sludge from beer factory (AS), activated sludge from whisky factory (SW), filter cake from sugar refinery factory (FC), castor meal (CM), inorganic fertilizer (F), and check (Ch) were used in the study. The results indicated that in RSC treatment, initial growth of rice as measured by dry matter of shoot and root and tiller number was very active until before flowering stage. After flowering, however, the plant showed N-dificiency symptom and slow growth were observed throughout planting period. In CM treatment, slow growth during initial growth stage was seen from plants grown in both Rangsit and Roi Et soils. After flowering, the plant in the treatment started growing rapidly until harvesting period. Relation between rice growth and yield was also observed in the experiment. Rice yield corresponded quite well with plant growth at the later growth stage. The yield could be ranked in the following order : Rangsit soil : F > CM >, AS, FC >/ SW, RSC >, Ch Roi Et soil : CM, F > AS, SW > RSC, FC >, Ch Most of released N from OWM was observed from the initial plant growth to flowering stage except that from CM which showed opposite result. If efficiency of OWM as N-source was considered, CM was regarded as the highest one when approximately 60% of its total N was available to the rice plant whereas RSC was among the lowest when only 6-8% of its total N could be utilized by the plant. In addition, nitrogen content in grain and straw of the rice grown in CM treatment was remarkedly high whereas that in RSC treatment was considerably low. It was noticeable that the rice plant grown in Rangsit soil applied with FC showed considerably high content of phosphorus in both grain and straw.
