The segregation modes and the selection efficiency of large vascular bundle(LBV) number and panicle characteristics were measured in three hybrid populations of rice. F_1 plants of the three crosses showed different direction and degree of dominance in vascular bundle number and panicle characteristics. The panicle neck diameter(ND), number of primary branches(PB) and LVB showed a typical normal distribution in F_2. When F_2 plants were divided into two groups up culm length of 90cm, the distribution of LVB number and panicle characteristics were not different between two populations. The selected and non-selected F_3 populations showed no difference in distribution of LVB number and panicle characteristics. However, F_3 populations grouped by culm length of 90cm showed different distributions in LVB and 100-grain weight among six characteristics observed. In F_2 populations, ND showed positive correlationship with PB, LVB number and grain number per panicle(GN). ND was positively correlated with PB, LVB number, GN and panicle length in selected and non-selected F_3 populations.

This study was conducted to obtain some basic informations by screening Oryza sativa cultivars available for direct sowing. Germination and emergence rate in low temperature (15℃), 1,000 seed weight, proline content and SOD activity of seed were investigated in 12 cultivars of glutinous rice and 14 cultivars of nonglutinous rice. Significant difference in germination rate was not observed among the cultivars, and emergence rate, germination speed and emergence speed varied among the cultivars, 2~87%, 4~99%, 2~72% in range. Emergence rate, germination speed and emergence speed were high in Oryza sativa "Daeripchalbyeo", "Baegna", "Sangnambatbyeo", "Sinseonchalbyeo", "Jeogna" and "Inbujinado", and low in O. sativa "Jado", "Hyangrni", "Dasanbyeo" and "Heugmi". Many native varieties of Oryza japonica with glutinosity showed high values in emergence rate, germination speed and emergence speed. Average number of days for emergence became shorter, as emergence rate of a variety was high, and the varieties with high emergence coefficient tended to belong to Oryza japonica cultivars with glutinosity. Negative correlation was observed between proline content and germination rate at low temperature, and very high positive correlation was recognized between proline content and SOD activity.

ABSTRACT Experiment was conducted to investigate the variation of grain quality in a panicle at experimental farm and laboratory of Kon Kuk University from April 1996 to March 1997.Spikelet number on the primary branch was ranged 5 to 6. However, spikelet number on the secondary branch was ranged 3 to 4.Total spikelet number on primary branches in a panicle was about 50 % in Hwaryeongbyeo and Chucheongbyeo. But it was only 35 % in Dasanbyeo which had a lot of secondary branches.Grain weight in the secondary branches were lighter than those in the primary branches. Protein content of milled rice in the primary branches was lower than that of milled rice in secondary branches, while amylose content of milled rice in primary branches was higher than that of milled rice in secondary branches. Protein content of milled rice on the upper part of branches was lower than that on the lower part of branches, while amylose content of milled rice on the upper part of branch was higher than that on the lower part branches in Chucheongbyeo. Fat acidity of rice flour on the primary branches showed lower value than on the secondary branches. Iodine blue value was the same as fat acidity value. Hardness of brown rice on the primary branches was stronger than on the secondary branches.

산업이 발달은 인간의 생활을 윤택하게 만들지만 다른 한편으로는 환경오염이라는 문제를 야기 시키고 있다. 특히 토양오염 중에서 농경지의 오염은 인간의 식생활과 밀접하기 때문에 더욱 심각한 사회적인 문제로 대두되고 있다. 그 중 토양의 주 오염물질인 납은 중금속 중에서 가장 널리 사용되는 반면에 그 독성은 모든 생물에 많은 피해를 주고 있다. 따라서, 이 실험에서는 토양내의 납에 대한 벼의 흡수능력과 축적부위를 정확히 진단하여 향후 중금속 오염에 대한 기초자료로 활용하고자 수행하였다. 1. 토양에서 pH 값은 IRI 268 품종을 포함하여 5품종에서 증가되었고, 값은 Dorae 품종을 포함하여 3품종에서 증가되었으나, 대부분 품종의 토양에서 pH와 Ec 값이 낮아지는 경향을 나타내었다. 토양에 잔류하는 납의 함량은 2.48∼5.42 mg kg^-1로 조사되었다. Danganeunbangju 품종을 재배한 토양에서 가장 높게 나타났고, Dabaegjo에서 가장 적게 잔류하는 것으로 조사되었다. 그러나 잔류율에서는 Baekna를 재배한 토양이 가장 높게 나타났다. 2. 납을 처리한 경우 백립중에서는 영향이 적은 것으로 조사되었으나, 건물중에서는 전체적으로 감소되는 경향을 나타내었다. 특히 Danganeunbangju와 Sanjo 및 IRI 268 품종이 다른 품종들에 비해 상당히 감소된 것으로 나타났다. 3. 벼 품종의 납 함량에서는 IRI 268, IRI 293, IRI 233, 그리고 Danganeunbangju 품종이 각각 잎, 줄기, 왕겨, 종실에서 높은 함량을 나타내었고, 축적율에서는 Sancheongdo, IRI293, Eunjo, Danganeunbangju 품종이 각각 잎, 중기, 왕겨, 종실에서 높은 축적율을 나타내었다. 지상부에서 벼 품종의 평균 납 함량은 잎>줄기>왕겨>종실 순으로 조사되었으며 축적율은 종실<잎<줄기<왕겨 순으로 조사되었다. 4. 토양내의 납의 잔류량과 건물중, 지상부의 납 함량과의 상관을 조사한 결과 토양의 납 잔류량과 건물중과는 고도의 부의 상관을 보였으며, 지상부의 납 함량과는 고도의 정의 상관을 나타내었고, 또한 건물중과 지상부의 납 함량은 고도의 부의 상관을 나타내었다. Rice (Oryza sativa L.) is an important crop plant that grows well on paddy soils. Recently, the contamination of paddy soil by heavy metals has become a very serious problem and for this reason a study was initiated to investigate Pb uptake and translocation in 29 rice varieties. Lead was applied to pots at the rate of 100 ppm, while other plots received no Pb. In the soils tested, the pH and electrical conductivity (Ec) values tended to be lower with Pb treatment, but these changes did not affect rice growth. The Pb concentration of soils ranged from 2.48 mg kg^-1 (Danganeunbangju) to 5.45 mg kg^-1 (Dabaegio) in the 100 ppm treatment and tended to be higher than in non-treated soils. The rate of residual Pb in the soils ranged from 4.4% (Danganeunbangju) to 98.0% (Baekna). There were no significant differences in 100-seed weight among the 29 rice varieties grown of Pb-treated soils. However, growth was depressed, other than panicle length and dry weight. In regards to the Pb concentration in the shoot, IRI 268, IRI 293, IRI 233 and the Danganeunbangju variety had the highest value in the leaf, stem, hull and seed, respectively. Sancheondodo, IRI 293, Eunjo and the Danganeunbangju variety were the highest in terms of the accumulation rate in the leaf, stem, hull and brown rice, respectively. Accumulated Pb was highest in the leaf, then the stem, hull and seed, and the accumulation rate was highest in the grain, then the leaf, stem and hull. The Pb concentration in the soil was positively correlated with the Pb concentration in the shoot in the 100 ppm treatment. However, the relationship between dry weight and the Pb concentration in the shoot was negatively correlated. Consequently, as Pb levels increased, growth became increasingly depressed. It is believed that excessive accumulation of these heavy metals can be toxic to most rice plants.

The 80% EtOH extracts on 16 rice varieties were screened for antioxidative activity. Antioxidative activity was measured by DPPH, TBA and SOD methods. There was difference of inhibitory activities on lipid peroxidation by DPPH and TBA methods. In DPPH method(CV = 6.03% ) , Jeokdo extracts have the highest activity as 29.8%. In TBA method (CV = 1.33%), Jangjo extracts have the highest activity as 90.6% . There was significantly different in the comparison between rice seed and seedling leaves extracts in SOD activity. In SOD activity Sangnambatbyeo(41.2%) has the highest activity on rice seedling leaves extracts and Ilpumbyeo(38.3% ) has the highest activity on rice seed extracts. Specially, Jangjo variety has high activity in the rice seed and seedling leaves extracts. The characteristics were evaluated by the nitro blue tetrazolium(NBT) reduction method. Rice seedling leaves contained three major SOD like two Cu/Zn SOD and one Fe SOD. However, no varietal differences were detected in the Cu/Zn SOD isozyme patterns. Relatively large differences in the levels of SOD and antioxidative activity detected in the rice varietites. In PKC activity, Soripchalbyeo and Shinseonchalbyeo had the highest activity 90.5% and 85.4%, respectively. In PLC activity, Ilpumbyeo that had high activity in PKC activity had the highest activity as 42.4%.
