摘要: 田間條件下對(duì)烤煙下,、中,、上3個(gè)部位葉片生長(zhǎng)發(fā)育過(guò)程中柵欄組織厚度、葉片厚度,、柵欄組織與葉片厚度比值3個(gè)葉片組織結(jié)構(gòu)特性的變化進(jìn)行了研究,。結(jié)果表明，烤煙在田間生長(zhǎng)發(fā)育過(guò)程中,，隨著煙葉部位的上升,，葉片柵欄組織厚度、葉片厚度,、柵欄組織與葉片厚度比值均表現(xiàn)為隨之降低的變化規(guī)律,。隨著煙株移栽后天數(shù)的增加，新鮮煙葉中,、上部葉片柵欄組織厚度的變化呈現(xiàn)逐漸上升的變化規(guī)律,；上部煙葉厚度也呈現(xiàn)逐漸上升的變化規(guī)律；而各部位煙葉柵欄組織與葉片厚度比值的變化無(wú)明顯的規(guī)律性,。3個(gè)煙葉部位之間葉片柵欄組織厚度的差異顯著,，而葉片厚度和柵欄組織與葉片厚度比值的差異均不顯著；在田間不同生長(zhǎng)時(shí)期3個(gè)性狀的差異也均不顯著,。煙株移栽后天數(shù)與柵欄組織厚度,、柵欄組織與葉片厚度比值之間呈極顯著正相關(guān)，而與葉片厚度之間呈不顯著正相關(guān),；煙葉柵欄組織與葉片厚度比值和柵欄組織厚度之間呈極顯著正相關(guān)(r=0.57**),；煙葉厚度與柵欄組織厚度之間也呈極顯著正相關(guān)關(guān)系(r=0.908**)。Abstract: The changes in palisade tissue thickness, leaf thickness, and their ratio in flue-cured tobacco green leaves during field were studied. Leaf samples were taken from different leaf positions and ages in Heilonjiang Province. The results indicated that palisade tissue thickness, leaf thickness, thickness ratio of palisade and leaf decreased with the increasing leaf positions. With the increasing days after transplanting, there was no distinct change pattern about thickness ratio of palisade and leaf. The difference in palisade tissue thickness in different leaf positions was significant. The days after transplanting were positive correlated with palisade tissue thickness and thickness rate of palisade and leaf. The significant positive correlation was observed between palisade tissue thickness and thickness ratio of palisade and leaf, and between palisade tissue thickness and leaf thickness.
