嫁接技术对烤烟生长发育的影响
|
摘要
[目的]探究嫁接技术对烤烟生长发育的影响。[方法]以烤烟品种云烟87、K326为接穗,以Coker176、贵烟9号为砧木,设计4种嫁接组合开展试验,分别测量了各时期农艺性状、根系性状、干物质积累、化学成分、关键酶活等指标。[结果]选用优良砧木后,嫁接烟株与自根烟株相比,烟株农艺性状、根系性状、干物质积累量等指标均有不同程度提高,化学成分变化不大,过氧化物酶、超氧化物歧化酶、几丁质酶等酶活指标均有提高。[结论]嫁接是改善烟株各项生理生化指标、增强抗逆性、促进烤烟生长发育的有效途径。
[Objective] To explore the effects of grafting technology on the growth and development of flue-cured tobacco. [Method] Four grafting combinations were designed with Yunyan 87 and K326 as scions and Coker 176 and Guiyan 9 as rootstocks. Their agronomic characters, root traits, dry matter accumulation, chemical composition and key enzyme activities were measured at different stages. [Result]Compared with the self-rooted tobacco plants, the agronomic traits, root traits and dry matter accumulation of the grafted tobacco plants were improved after using the good rootstocks. The chemical composition of the grafted tobacco plants did not change much, and the activities of peroxidase, superoxide dismutase and chitinase were improved. [Conclusion] Grafting was an effective way to improve physiological and biochemical indexes of tobacco plants, and to enhance stress resistance and promote the growth and development of flue-cured tobacco.
