摘要

A variety of products were tested as growth stimulants on short-day onions in the Vidalia growing region of southeastern Georgia over several years. These included 2-hydroxypropanoic acid, humic acid, cytokinin, and seaweed extracts. These products whether applied as a foliar spray or as a transplant dip did not have any affect on onion growth, yield, or graded size. In one year cytokinins (foliar or soil Triggrr) and humic acid, seaweed extracts & micronutrients (Super Shot 40 & Super PGA VII Plus)had a higher percent marketable onions after 4.5 months of controlled atmosphere (CA) (3% O_2, 5% CO2, 34 deg. F.) storage compared to the untreated check. The 2-hydroxypropanoic acid treatment did not, however, differ for CA storage from the check of plain water with surfactant. These growth stimulants have been reported to have positive effects on many plants including onions in some cases, but without consistent results from one study to the next or from one year to the next these products are of marginal usefulness in onion production.
