| 中文摘要: |
| 对贵州地区推广种植的烤烟品种红花大金元、K326、云烟87、云烟97 的烟叶腺毛密度、腺毛
分泌物成分、石油醚提取物含量等进行分析，比较各品种的差异，以选出较适宜该地区的烤烟品种。结果表
明：腺毛密度表现为K326> 红花大金元> 云烟87> 云烟97，腺毛脱落率以云烟87 最小，且腺毛随着烟叶
成熟度的增加而脱落；主成分分析表明，腺毛分泌物组分含量表现为云烟87> 云烟97>K326> 红花大金元；
石油醚提取物含量表现为云烟97> 红花大金元> 云烟87>K326，其中烤烟生长期95~110 d 的烟叶石油醚提
取物增加量表现为云烟97>K326> 云烟87> 红花大金元，且石油醚提取物含量随着烟叶成熟度的增加而增
加，但超过一定成熟度后石油醚提取物含量不再增加反而降低。综合比较，云烟87 烟叶腺毛脱落率相对较
低，石油醚浸提物含量相对较高，腺毛分泌物含量综合排名最高，是贵州地区较适宜种植的烤烟品种。 |
| 英文摘要: |
| In this study, the density of glandular hair, secretions of glandular hair and the content of petroleum
ether extract of flue-cured tobacco varieties such as Honghua Daikin, K326, Yunyan 87 and Yunyan 97 in Guizhou
area were analyzed, and the differences among varieties were compared to select suitable flue-cured tobacco varieties
in this area. The results showed that the density of glandular hair was K326 > Honghua Daikin > Yunyan 87 > Yunyan
97, the glandular hairy rate was the smallest in Yunyan 87, and the glandular hair fell off with the increase of tobacco
maturity. The principal component analysis showed that the components of glandular hair secretions ranked Yunyan
87 > Yunyan 97 > K326 > Honghua Daikin; the content of petroleum ether extract ranked Yunyan 97 > Honghua
Daikin > Yunyan 87 > K326, the increasing amount of petroleum ether extract of tobacco leaves with 95-110 days was
Yunyan 97 > K326 > Yunyan 87 > Honghua Daikin in turn, and the content of petroleum ether extract increased with
the increase of tobacco maturity, but the content of petroleum ether extract no longer increased after a certain degree of
maturity. A comprehensive comparison showed that in Yunyan 87, the abscission rate of glandular hairs was relatively
low, the content of petroleum ether extract was relatively high, and the content of glandular hair secretions was the
highest, which was the suitable flue-cured tobacco variety for planting in Guizhou area. |
