Changes in Ratio of Palisade Tissue Thickness to Leaf Thickness in Flue-cured Tobacco Leaves

烤烟叶片栅栏组织与叶片厚度比值的变化

As a rule, the primary leaves and the 1-4th trifoliolate leaves have greater leaf thickness and more number of palisade cells per unit leaf area.

初生叶和1&4节位的叶片较厚，单位叶面积栅栏细胞数目多；

The results showed that there were significant differences in stomata density, epidermis length, epidermis width, epidermis thickness, cuticle thickness, leaf thickness, layer of the mesophyll thickness and the diameter of the vascular bundle.

结果表明：这些假俭草在气孔密度、表皮细胞长度、表皮细胞宽度与厚度、角质层厚度、叶片厚度、叶肉层厚度、维管束直径的大小等方面有显著的差异。

The proportion of the upper epidermis thickness to the whole leaf thickness increased obviously in silvered leaves, but that of the palisade tissue thickness to the whole leaf thickness decreased at a small degree.

病叶上表皮厚度占叶片厚度的比例明显增加，栅栏组织厚度占叶片厚度的比例略有减少。

With increasing elevation, the leaf area, leaf thickness, palisade mesophyll thickness, spongy mesophyll thickness, stomatal area, epidermis cell area and pubescence density were increased, while cutin membrane thickness, epidermis cell density, pubescence length, and stomatal density were decreased.

mm-2.随海拔升高叶面积、叶厚度、栅栏组织和海绵组织的厚度、气孔器面积、表皮细胞面积以及表皮毛密度呈增加趋势，而角质膜厚度、表皮细胞密度和表皮毛长度则呈减小趋势；

The leaf dissection showed that with the light intensity increased, leaf thickness, ( horniness) layer thickness, relative thickness of railing tissue added, relative thickness of sponge tissue shrinked and the contents of chlorophyll increased.

叶片解剖表明，随着光照强度的增加，叶厚度增加，角质层、栅栏组织的相对厚度增加，海绵组织的相对厚度减小，叶绿素含量逐渐增加。

For species Magnolia grandiflora, the PAHs concentrations increased with the increases of palisade tissue thickness, ration of palisade to spongy tissues, total leaf thickness, stomatal length and stomatal width.

广玉兰叶片随栅栏组织厚度、栅栏-海绵组织比值、叶片总厚度、气孔长度和气孔宽度这些相关结构的增大，PAHs含量呈上升的趋势。

Internode length, the first node of fruit branch, fruit branch length, leaf thickness, cotton boll weight, 2.5% span length significantly related to fruit branch types.

与果枝类型显著相关的性状有果节距、果枝始节、果枝长、叶片厚度、铃重、2.5%跨长等。

The change in leaf thickness is highly correlated with the thickness of palisade tissue.

叶厚度与栅栏组织厚度呈高度相关。

Drought conditions led to changes in morphology of Rosa, such as decreased plant height, and increased leaf thickness, decreased stomatal density but increased stomatal depth; UV-B radiation further increased the impact on Roxburgh rose by drought.

干旱条件导致了刺梨形态的变化，如减少了植株高度、增加了叶片的厚度、降低了气孔密度但增加了气孔深度；UV-B辐射进一步增加了干旱对刺梨的影响。

The results showed that foliage dressing increased leaf thickness, leaf area, leaf weight, number of inflorescence, bearing branch length and number of leaves, etc.

本试验就叶面肥料对枣树生长发育前期的影响进行了研究，结果表明：叶面施肥可增加枣树叶片厚度、叶面积、百叶重、花序数、枣吊长度及叶片数等。
