中文摘要 | 使用大豆有限型品種6個及無限型品種4個,播種於春夏秋三個季節及45×20,45×15,45×10,45×5cm 四個栽培密度,分析有限型與無限型間農藝性狀之變異性,結果如下: 株高、主莖及分枝節數,主莖及分枝莢數、粒數、乾重、產量、開花增加株高,開花期間,成熟期,油分含量及主莖的葉柄長及葉長之個體內變異係數等性狀均呈無限型大於有限型。而開花期,蛋白質含量及百粒重則呈有限型大於無限型。在不同密度下兩型一般除株高,開花後增加株高依密度增加而遞增外,其他如:產量及其構成因素等均呈遞減之傾向。在不同栽培季節,兩型之產量及其構成因素一般均呈夏作最大,春作次之,秋作最小之結果。 各農藝性狀對季節之適應性,無限型大於有限型。以栽培季節及密度為7個環境根據FINLAY, et al (1963) 與 FBERHART, et al (1966)之方法分析結果:無限型大部分品種之產量安定性及平均產量大於有限型,同時較適應春夏,及春秋季節。 |
英文摘要 | Six determinate and four indeterminate varieties of soybeans were grown in three crop seasons, spring, summer and fall with four planting densities to study the variabilities of several agronomic traits. The results showed that plant height, node and pod number of main stem and branch, seed number, dry weight, seed yield, plant height increased after flowering, period of flowering, days of maturity, oil content and c.v. within the individual plant of petiole and leaf length on main stem of the indeterminate type were greater than determinate type. Days to flowering, protein content and 100 seed weight of determinate type were greater than indeterminate type. Plant height and plant height increased after flowering were increased as plant density increased in both types and all other traits were decreased. The yield and its relative traits of both types showed highest in summer crop, intermediate in spring crop and lowest in fall crop under different seasons. The agronomic traits of indeterminate type were more adaptable to seasonal variation than the determinate type. By using the method of FINLAY et al (1963) and EBERHART et al (1966) to analyze seven environmental factors of different crop seasons and planting densities showed that the yield stability and average yield in most varieties of indeterminate type was greater than determinate type and also were more adapted to spring-summer and spring-fall seasons. |
