-
摘要: 研究了白肋煙上部葉和中部葉的上表皮、下表皮和全表皮腺毛密度在不同品種間的差異,。結(jié)果表明,，白肋煙煙葉腺毛以長(zhǎng)柄腺毛、短柄腺毛和無(wú)頭腺毛為主,，煙葉各類型腺毛密度在不同品種,、同一品種不同部位及同一部位的上下表皮間存在一定差異。煙葉總腺毛密度中部葉高于上部葉,，上表皮高于下表皮,。上部葉的上表皮總腺毛密度以品種JB04-05 的最大，下表皮總腺毛密度以品種22081 和23014 的最大,，上部葉總腺毛密度以22084 和JB04-05 的最大,，鄂煙1 號(hào)的密度最小。中部葉的上表皮總腺毛密度以22081 和22084 的最大,，下表皮及全表皮總腺毛密度以22074,、22081 和22084 的最大。Abstract: This study analyzed the difference of tobacco leaf glandular trichome density of coronas and cutters among different burley tobacco varieties. Results showed that long-stem glandular trichome, short-stem glandular trichome and non-cell glandular trichome took most part of all glandular trichome. The density of all types of glandular trichome was different in burley tobacco varieties, also in different-positioned leaves of the same variety as well as in upper or lower epidermis in the same positioned tobacco leaves. The density of total glandular trichome in cutters was more than that in coronas. For coronas, the variety of JB04-05 had more glandular trichome than other eight varieties in upper-epidermis. In lower-epidermis, the varieties of 22081 and 23014 had more glandular trichome density than others. Compared to Eyan1, which had the least glandular trichome density, the varieties of 22084 and JB04-05 had the more glandular trichome in coronas. For cutters, the varieties of 22081 and 22084 had more glandular thichome in upper-epidermis than other varieties. The varieties of 22074, 22081 and 22084 had more glandular trichome density on lower or upper and lower epidermis.
