담배 摘芯前 및 後의 腋芽發生의 品種間 差異 = Varietal Differences of the Sucker and Ground Sucker Development in Nicotiana tabacum L.

다국어 초록 (Multilingual Abstract)

1.Differences of ground sucker development among varieties were shown. The peak time of developing the ground suckers were eight weeks after transplanting influe-cured, and six weeks in local varieties. Burley varieties showed little development of ground suckers.
2.Dry weight per a ground sucker was large in local, medium in flue-cured, and seal 1 in burley varieties.
3.In flue-cured varieties, the dry matter of ground sucker was large in Coker 139, BY 4 and Va 115, and small in NC 82 and Nc2326.
4.Burley varieties had the most number of suckers and Cheongjuyub the least primary suckers of Ky10, secondary suckers of Burley 21 and Coker 139, and tertiary suckers of the other varieties were shown as the peak developing time, Local varieties had few or no quadratic suckers.
5.The growth rate of ground suckers and suckers of Hyangcho was remarkably larger than any other varieties. Burley varieties had small ground suckers relatively large suckers. Cheongjuyub had large ground suckers and small leers. Flue-cured varieties lay between the burley and local varieties.
