OED保鮮劑對於稻谷抑制發芽之研究

Abstract

本試驗為明嘹應用OED藥劑來處理濕稻谷，是否能抑制其發芽及其處理後，稻谷內成分變化情形，以減少本省南部第一期作，北部第二期作水稻，由於收穫期問逢下雨而遭發芽之損失，所用的稻谷為臺中在來1號（印度型）和臺南5號（日本型），以OED藥劑0%，0.5%，1.5%，2.5%濃度處理，其結果，如圖1～6及表1、2，茲將其摘要如下： 1. 以OED藥劑處理濕稻谷（含水量30％以上）的確有抑制發芽的效果，其最適濃度1.5%，2.0%。但對根之生長抑制更有效。 2. 經OED藥劑處理之稻谷，其成分變化情形，不很明顯，但是影響糙米率的大量減少，如蓬萊稻減少5～8%，在來稻減少11～27%，此點實值得注意。

Two varieties of rice Taichung native 1 (indica type) and Tainan 5 (japonica type) were treated with “OED” perservitive and its effects on germination, root growth and grain quality were studied. It was found that “OED” inhibited seed germination well at the concentration of 1.5 to 2.0 percent. The root growth was more severely affected by “OED” than germinability. Quality of rice in term of protein, starch and moisture contents were not affected, however, the yield of brown rice was affected with 5-8% and 11-27% decrease in Taichung native 1 and in Tainan No.5 respectively.
