金洪珪,安壽泰 충남대학교 농업과학연구소 1987 農業技術硏究報告 Vol.14 No.2
This experiment was conducted to study plant characteristics and dry matter production of several rice varieties, The results are summarized as follows. 1. Culm length was gradually shortened as varieties were improved and showed significant decrease in Japonica Ⅹ Indica hybrids. 2, Panicle length seems to be shortened as varieties changed from group Ⅰ to group Ⅲ. However, varieties in group Ⅳ had longer panicle length in spite of shortening tendency in other groups. 3. Leaf blade length was decreased as varieties improved, but leaf blade width was increased. 4. Panicle exertion showed significant decrease as varieties improved. 5. Number of panicles per square meter among Japonica varieties was gradually increased and similar to the number of spikelets per panicle. Number of spikelets on Indica Ⅹ Japonica hybrids were higher than Japonica varieties, whereas 1,000 kernel weight was slightly decreased. 6. Dry weight of leaf sheath and culm, and leaf blade was highest at the time of heading and the weight of panicle showed significant increase between 10 and 20 days after heading. 7.. The maximum crop growth ratios of leaf blade, stem and panicles were attadined at the stage of i heading, booting and milking, respectively. 8. The distribution ratio of dry matter was higher in leaf blade than in stem at the tillering stage. A the heading stage, the distribution ratio of dry matter was higher in order of culm, leaf blade and panicle. At the maturing stage, the ratio was higher in order of panicle, stem and laf blade. 9. Correlation coefficients among grain yield, harvest index, and biological yield were all signific r and they were positive.
