Park, Kyeong-Bae ; Tanaka, Takayuki ; Harada, Jiro ;
Korean Journal of Crop Science, volume 23, issue 1, 1978, Pages 1~4
The change of soluble protein components in leaf discoloration of rice plant was investigated in the Growth Cabinet with various temperature conditions. The ratio between high molecular soluble protein and low molecular soluble protein was high under high temperature condition, while low under low temperature condition, and also lower in Indica type varieties than Japonica type variety.
Effect of Cultivating Time on the Growth and Yield of Milyang 23
Korean Journal of Crop Science, volume 23, issue 1, 1978, Pages 5~13
An experiment was carried out to find out effective heading date and period of limited ripening in different regions of climatic conditions by sowing date and length of nursery stage of a new variety Milyang 23. Since varieties of Tongil line have a character of premature heading, these do not show the symptom of senescent even though length of nursey stage was delayed. And the delay of heading date is due to late transplanting date, on the other hand, length of nursery stage delayed.

Kyeong-Bea Park ; Ho-Sung Ha ;
Korean Journal of Crop Science, volume 23, issue 1, 1978, Pages 14~20
To find out the influence of mineral nutritions and phosphorus concentration to ferrous absorption of rice and barley plants were studied in the culture solution which has various levels of ferrous and phosphorus with deficiency of mineral nuritiont. The ferrous absorption of rice and barley plants were greatly affected by phosphorus and potassium in the culture solution among mineral nutritions. The ferrous absorption was decreased with the increasing of phosphorus concentration. The rate of ferrous translocation was higher in barley plant than that of rice plant. And also, the symptoms of ferrous toxicity occurred easily in the barley plant. From these results, it was concluded that the ferrous was more influential upon the growth of barley than that of rice.
Studies on the Intergeneric Hybridization in the Triticale II. Newly Established Primary Winter Octaploid Triticale by Intergeneric Hybrid between T. aestivum L. and S. cereale L.
Chang-Hwan Cho ;
Korean Journal of Crop Science, volume 23, issue 1, 1978, Pages 21~25
Primary triticale was newly established by colchicine treatment of intergeneric hybrid F 1 plants crossed between T. aestivum var. Jugoku #81 and S. cereale var. Jaelae. The agronomic and cytological characteristics were studied.
Studies on the Wet-injury Resistance of Wheat and Barley Varieties. IV. Effect of Excess-Moisture in the Soil on the Growth of wheat, six row and two row barley at Various Stage
Hyung-Soo Suh ;
Korean Journal of Crop Science, volume 23, issue 1, 1978, Pages 26~31
Effect of over flooding moisture levels on the growth and yield of barley and wheat crops was determined. The marked plant height retardation of barley under over saturated moisture treatment was observed at the elongating stage and wheat at the booting stage. The elongating and tillering stage subjected to over flooding moisture level significantly reduced panicle number and grain number per panicle, and 1000-grain weight reduction at the booting stage streated with over saturated moisture level. The highest yield reduction of two row and six row barley stage, under over flooting moisture level. Soil wet resistance observed in decreasing order; wheat<six row barley<two row barley.
Studies on the Screening for Cold Tolerance in Soybean
Shin-Han Kwon ;
Korean Journal of Crop Science, volume 23, issue 1, 1978, Pages 32~35
In order to screen cold tolerant soybean lines, germination at various temperature, and emergence and seedling height at 1
were investigated. Since the most conspicuous varietal difference of the germination speed was observed at 1
, the germination test at 1
would be effective in screening cold tolerant lines.

Bong-Ho Choe ; In-Sup Lee ; Ja-Sung Cho ; Jong-Sung Park ;
Korean Journal of Crop Science, volume 23, issue 1, 1978, Pages 36~43
Ears collected from 500 regions were phenotypically observed for their ear and kernel characters. Characters studied included ear shape, kernel color, kernel density, ear row number, starch quality, pop corn and waxy corn, ear length, ear diameter, kernel length, kernel width, kernel weight, ear weight, and 100 kernel weight. The Korean local corn collected were mostly flint type and were very diverse in all the characters studied. The collected local corn would be very promising for providing good germplasm for corn breeding in the future.
Effect of Phosphate Application on Soybean in the Newly Cultivated Hill-side Field
Son-Goo Hang ; Chun-Bae Kim ;
Korean Journal of Crop Science, volume 23, issue 1, 1978, Pages 44~50
The increased application of phosphate on soybean grown in a newly cultivated hill-side field resulted: positive correlation phosphate content in soil and stem length. number of branches and yield. and between increased application of phosphate and yield and yield components. 46.2kg/10a of phosphate application out yielded by 69％ the nonapplied plot.
Estimate of Optimum Plot Size and Shape for Rape Yield Trials
Korean Journal of Crop Science, volume 23, issue 1, 1978, Pages 51~54
3∼6m long plot with 3-4 replications will be practical for yield trials in the early hybrid generations. The C. V. values with 9m long plot was about 6.6％ in variety Yudal and 13.9％ in 12m plot. These results indicate that 9-12m plot with 3-4 replications could be employed in securate yield test in the advanced generations.
Studies of Seed Germination in Panax ginseng C. A. Meyer III. Seasonal Changes of Germination Inhibitors during Ripening
Choe, Gyeong-Gu ; Norindo Takahashi ;
Korean Journal of Crop Science, volume 23, issue 1, 1978, Pages 55~59
This study was carried out to investigate the sea sonal changes of the contents of inhibitors in leaves and fruits of Ginseng plant during ripening. Three kinds of inhibitors in leaves and all parts of fruit, i.e., seed, sarcocarp and endocarp were recognized at the Rf 0.1, 0.4-0.6 and 0.8-1.0 zones by the bioassay of lettuce seed germination. Among them, the level of the inhibitor at the Rf 0.4-0.6 zone in leaf and seed increased most significantly in accordance with fruit ripening. The activities of three inhibitors found in endocarp gradually decreased during ripening.
Control of Perennial Weed Scirpus maritimus L. in Reclaimed Paddy Fields of West Seashore I. Distribution of S. maritimus
Korean Journal of Crop Science, volume 23, issue 1, 1978, Pages 60~63
The survey was carried out over an area representing about 29％ of the reclaimed paddy fields of west and south seashore in Korea. Scirpus maritimus L. was heavily infested all over the reclaimed paddy fields. But the weed was scarcely found in double cropping fields cultivating barley at paddy after rice or in reclaimed paddy fields where the cultivation was taken a long time.
Control of Perennial Weed Scirpus maritimus L. in Reclaimed Paddy Fields of West Seashore II. Physiological and Ecological Characteristics of S. maritimus
Korean Journal of Crop Science, volume 23, issue 1, 1978, Pages 64~73
To gain a better understanding of the germination and growth of Scirpus maritimus, pot and field experiments were conducted to observe the development of new rhizomes and tubers, the growth rate of culms. and the germination behaviour of tubers of this perennial weed. Tuber placement, water depth, salinity and pH were also observed for their possible influence on the growth of S. maritimus.
Control of Perennial Weed Scirpus maritimus L. in Reclaimed Paddy Fields of West Seashore III. Control of S. maritimus with Herbicides
Korean Journal of Crop Science, volume 23, issue 1, 1978, Pages 74~80
To identify new herbicides for the control of Scirpus maritimus and evaluate the performance of some promising herbicides for transplanted rice, field experiments were carried out in the reclaimed paddy fields.

Byeung-Hwa Kang ; Kil-Ung Kim ;
Korean Journal of Crop Science, volume 23, issue 1, 1978, Pages 81~85
Competitive ability was determined for two different varieties, Josaengtongil (early maturing indicajaponica type) and Jinheung (medium maturing japonica type), against Cyperus serotinus(nut sedge). An increase of rice density increased competitive ability of rice to C. serotinus. The results indicate that the use of tall and medium maturingvariety like Jinheung provides better competitive ability against C. serotinus than Josaengtongil, a semi-dwarf and early maturing type.

Jong-Yeong Pyon ; Young-Rae Kim ;
Korean Journal of Crop Science, volume 23, issue 1, 1978, Pages 86~89
The competitive effects of annual weeds on soybeans (Glycine max. (L.) Merr. 'Gwang Gyo') were Studied on silt clay loam soil. Weeds allowed to grow in the row for 2, 4, 6, 8, 10 weeks after soybean planting and full season reduced soybean yields 6.5, 3.2, 10.7, 8, 8.24.4, and 44%. respectively. Reduction in leaf area index (LAI) and crop growth rate (CGR) of soybeans were closely correlated to percent soybean yield reduction. Weed com petition showed to reduce the number of soybean pods per plant, the number of branches per plant, and plant height.
