摘　　要：通过对丽江市引进的10个烤烟新品种(‘云烟98’、‘云烟110’、‘云烟113’、‘云烟114’、‘云烟115’、‘云烟202’、‘H3’、‘MSK326’、‘T29’和‘XYN87’)田间性状及烟叶组织结构的比较,为当地选择优良品种种植提供参考。结果表明:(1)10个烤烟新品种均能较好地适应当地的生态条件和栽培措施,品种‘T29’生育期明显长于其余品种,它与‘XYN87’、‘H3’的农艺性状表现最好;(2)‘云烟110’、‘XYN87’、‘MSK326’和‘H3’等品种的叶片组织结构表现最优,‘云烟113’和‘T29’表现最差;(3)各品种叶片组织结构中,组织比变异系数最大,达26.51%,叶厚和栅叶比最小,分别为15.93%和13.42%,栅栏组织厚度与叶片厚度、组织比、栅叶比呈极显著正相关,与海绵组织厚度成显著正相关。通过相关栽培措施可以使农艺性状表现好的品种烟叶组织结构得到改善。For the purpose of the selection the superior flue-cured tobacco cultivars for Lijiang area,the field properties and dissecting structure of leaves of ten newly introduced flue-cured tobacco cultivars＇（Yunyan98＇,＇Yunyan110＇,＇Yunyan113＇,＇Yunyan114＇,＇Yunyan115＇,＇Yunyan202＇,＇H3＇,＇MSK326＇,＇T29＇and ＇XYN87＇）were measured.The results showed：（1）The new ten flue-cured tobacco cultivars can adapt the local ecological environment and farming system well,＇T29＇had the longest growth period,＇T29＇,＇XYN87＇ and＇H3＇had the best agronomic characters.（2）＇Yunyan110＇,＇XYN87＇,＇MSK326＇and＇H3＇had the best leaves＇dissecting structure,however,＇Yunyan113＇and＇T29＇were on the contrary;（3）Coefficient of variation of palisade/spongy tissue thickness ratio was the biggest,which was 26.51%,but leaf thickness and palisade/leaf thickness ratio were the least,that were 15.93% and 13.42%,respectively.Palisade tissue thickness had significant positive correlation with leaf thickness,palisade/spongy tissue thickness ratio and palisade/leaf thickness ratio,had positive correlations with spongy tissue thickness.The study also indicated improving cultural practice can make the dissecting structure of flue-cured tobacco leaves that had good agronomic characters better.
