摘要

本研究係利用47個水稻品種（系）分別種植於台灣中北部個地點，以瞭解地點及品種對水稻植株矽含量之影響。結果發現4個地點之葉片矽含量，由高至低為彰化大村5.41％、苗栗公館4.98％、苗栗苑裡4.49％、苗栗市4.18％。在栽培地點及品種間之間交感作用達顯著差異，顯示葉片矽含量受品種及栽培地點影響。彰化大村32個水稻品種中，分秈型稻、秈糯型稻、稉型稻及稉糯型稻等4類，參試品種中除稉型稻台中65號外，以秈型稻高於稉型稻。分析稉型稻台東30號及吉野1號與秈型稻台中在來1號雜交後裔之葉片矽含量，其分佈由2.84％到5.03％。綜合試驗結果得知，水稻矽含量受品種及種植地點之影響，且藉由育種手段可改良水稻矽含量之特性。

In order to study the effects of locations and varieties on silicon content in rice plants, 47 varieties and lines of rice plants were planted in four locations in northern and central Taiwan. The results indicated that silicon content in the leaf blade of rice plants differed from one location to another. The silicon content of rice plants grown in the experimental sites of Tatsuen (Changhua County), Kungkuan (Miaoli County), Yuli (Miaoli County) and Miaoli City, was 5.41%, 4.98%, 4.49%, and 4.18%, respectively. The interaction of rice variety and location was significantly (F-value 8.9) indicated that the change in silicon content of leaf blade in responding to the interaction of genotypes and locations. In Tatsuen, generally higher silicon content in the leaf blade of indica type rice than japonica type rice varieties was observed among 32 varieties (japonica, and japonica glutinous types, as well as indica and indica glutinous types), with the exception of Taichung 65. In another experiment, we found that the silicon content of rice leaves varied from 2.84% to 5.03% in the segregating progenies of crosses among varieties of indica and japonica genotypes (TT30/CY1//TN1). It was concluded that the silicon content enhancing the blast disease resistance in rice plants was interacting with variety and location, and it was genetically controlled and could be improved through breeding.
