 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Effect of Treated Seeds with H subscript 2 BO subscript 3, GA subscript 3, KNO subscript 3 and ZnSO subscript 4 on Seedling Growth of Sweet Corn and Yard Long Bean) ผู้เขียน: Panie Temesagdie, Taikichi Takano สื่อสิ่งพิมพ์:pdf AbstractGibberellic acid (GA subscript 3), boric acid (H subscript 2 BO subscript 3), zince sulfate (ZnSO subscript 4) and potassium nitrate (KNO subscript 3) was applied during the imbibition stage of germination process. It was found that 50 ppm GA subscript 3 could not improve percentage of seed germination, but it promoted root growth and accumulation dry matter of seedling. The application of 3-9 ppm Boron of H subscript 2 BO subscript 3 or application of 1 and 5 ppm ZnSO subscript 4 could upgrade germination percentage of sweet corn and yard long bean seeds. Furthermore, seedling root length and seedling dry weight were increased by these applications, particularly in low vigour seeds. Application of 5-10 meq.l superscript -1 KNO subscript 3 retarded germination of sweet corn and yard long bean seeds. |
