摘 要: | [目的]为了研究黄化病对葡萄生长发育的影响。[方法]以吐鲁番主栽品种无核白和无核白鸡心为试材,通过对不同黄化程度葡萄的叶片生长量、叶绿素含量及果实产量等指标进行对比分析。[结果]黄化对葡萄植株生长、果实产量和品质造成了严重危害。随着葡萄黄化程度的加剧,两种葡萄植株的单叶重、叶长、叶宽及单叶厚等逐渐减小,且黄化株生长量较正常株明显下降。黄化植株葡萄的产量较低,两种葡萄正常园产量分别是黄化园产量的2.47倍和2.51倍,果粒大小和可溶性固形物也显著低于正常植株。采用不同方法提取叶绿素含量比较得出,利用丙酮研磨法提取两种葡萄叶绿素含量的效率均优于乙醇浸泡法。[结论]黄化病造成葡萄叶片光合代谢失调,植株生长迟缓,严重威胁着吐鲁番葡萄产业的健康发展。对黄化病的发生原因进行深入分析,并采取有效的防治措施是现在葡萄生产上比较棘手的问题。

Effect of Chlorosis on grape growth and development |
| |
Abstract: | The main cultivars of Turpan‘Thmopson seedless’and‘Centennial seedless’were taken as testing materials to study the influence of chlorosis on grape growth and development. The indexes of leaf growth increment, chlorophyll content, fruit yield under different degrees of chlorosis were analyzed. The results showed that the chlorosis caused serious harm to grape growth and the yield and quality of fruits. Along with the intensifying of chlorosis, the single leaf weight, leaf length, leaf width and single leaf thickness of these two grape cultivars reduced gradually, and the growth increment of chlorotic grape plants was significantly lower than that of normal plants. The grape with chlorosis had lower yield, and the normal orchard yield of the two cultivars was 2.47 and 2.51 times of chlorotic orchard yield, respectively. The fruit size and soluble solid content of chlorotic grape were significantly lower than that of normal grape. By comparing different extracting methods of chlorophyll content, it was showed that the efficiency of acetone grinding was better than that of ethanol immersion. The occurrence of chlorosis could cause metabolic disorder of photosynthesis of grape leaves and slow plant growth, and severely threaten the healthy development of grape industry in Turpan. Therefore, adopting effective measures to control chlorosis in grape orchard should be the focus of grape production in Turpan. |
