不同成熟度煙葉結(jié)構(gòu)顯微分析
The Analysis of Microstructure of Tobacco Leaf during Maturing
-
摘要: 不同品種成熟過程略有差別,，成熟過程中未熟或初熟到適熟期葉片厚度、柵欄組織細(xì)胞長度是逐漸增加的,，而后才開始下降,，葉片疏松度則是持續(xù)增加的。因此在采收適度成熟的葉片,，結(jié)構(gòu)疏松度恰當(dāng),，有利于提高烤煙質(zhì)量。成熟過程中氣孔顯微結(jié)構(gòu)比較穩(wěn)定,，但氣孔調(diào)節(jié)能力逐漸下降，保衛(wèi)細(xì)胞內(nèi)葉綠體數(shù)量也是逐漸減少的,，可以作為成熟度評價的參考Abstract: The maturing process was different between K326 and HD, and the maturity was different in breeds. While maturity thickness of leaf, length of palisade cells increased gradually, then declined, spacing of leaf increased gradually. So the structure of ripe leaf loosened properly, and it made for tobacco quality. The structure of stoma stabilized, but function fall during maturing, and the number of chloroplast in guard cell drooped, and it might be a symbol for maturing.
