大气压等离子体处理对番茄生长发育及产量与品质的影响

目的]通过等离子体对番茄种子处理，观测番茄植株生长发育和产品品质的变化，从而找到可以提高番茄产量以及抗病性的等离子体最佳电压范围。方法]利用大气压等离子体装置对番茄种子进行处理，研究不同电压（4760～6800V）大气压等离子体处理番茄种子后对番茄植株生长及产量品质的影响。结果]不同电压的等离子体处理后对番茄植株生物性状的影响效果不同，等离子体处理的7个组的单果重（〉80g）、果长（≥5．2cm）、果粗（≥5．5cm）均比对照（OK）有明显提高。处理后的番茄抗病毒病除第6组和第7组与对照CK发病率相同外，其他组的病毒发病率均为2．08％。等离子体处理的7个组的总产量均比对照（CK）高，产量最高的前3位分别是第5组、第4组、第3组。总产量分刖比CK提高26．56％、20．31％和16．55％。结论]等离子体处理电压范围在5440—6120V对番茄大多数指标效果较好，最好的是5780V和6120V处理。番茄总产量和抗病性方差分析及回归预测与试验数据基本吻合。
