  cotton petioles
No significant correlations were observed between levels of dietary N compounds in cotton petioles and numbers of whiteflies, either adults or immatures, on the cotton plants.
      
Sampling dates and N application treatments affected levels of soluble proteins in cotton petioles, and interactions between sampling dates and treatments were significant.
      
To determine whether these positive responses were related, we measured the levels of dietary N compounds (proteins and free amino acids) that would be available for insect nutrition in cotton petioles at the different N application rates.

The anatomical structure of boron-deficient cotton petioles changed in the following order when petiole rings appeared: firstly, vascular cambium abnormally thickened; secondly, pith cells deformed and abnormally thickened: thirdly, some vascular bundles cross-linked, their configuration disordered and cells deformed. Then. some particle mass could be found in pith cells. Later, the structure of the parenchyma cells in the xylem disappeared and phloem cells partly disintegrated. At the last stage of petiole rings, the number of sieves and vessels of boron-deficient petioles decreased, their shapes changed, while their diameters were reduced. It was also found that sieve piths were plugged by calluses and the proportion of scalariform ducts and pitted vessels declined.

缺硼的棉花叶柄上有墨绿色的环带形成,用扫描电镜观察发现环带部位的维管形成层、木质部、韧皮部及髓部组织的结构均发生异常变化,对叶柄的运输功能产生严重影响。
