摘要

实验的目的是通过使用植物生长调节剂（PGRs）来解决干物质向根茎分配不均的问题。因此，在 2020-22 年期间，使用 IISR Varada 品种进行了两次盆栽试验，以研究叶面喷施 PGRs（6-BAP、赛可宝、GA3 和 PBZ，五种不同浓度，即对照、50ppm、100ppm、150ppm 和 200ppm，三次重复）对生长和产量的影响。试验采用多室条件下的因子CRD设计。结果表明，6-BAP（100ppm）能显著增加分蘖数、二级根茎数、三级根茎数、根茎长度、根茎直径和根茎产量（322.3 克/株），比对照高出 240%。

Eﬀect of growth regulators on the growth and yield of ginger (Zingiber oﬃcinale Rosc.) under polyhouse condition

The experiment has been conducted to resolve the poor partitioning of dry matter towards rhizome by using plant growth regulators (PGRs). Therefore, two pot culture experiments were conducted during 2020-22 using the variety IISR Varada to investigate the eﬀects of foliar application of PGRs (6-BAP, cycocel, GA3 and PBZ at five diﬀerent concentrations viz. control, 50ppm, 100ppm,150ppm and 200ppm in three replications) on growth and yield. The experiment was laid out in Factorial CRD design under polyhouse condition. The results revealed that 6-BAP at 100ppm significantly increased the number of tillers, secondary rhizomes, tertiary rhizomes, length, diameter of rhizomes, and rhizome yield (322.3g/ plant) which is 240% more than the control.
