本研究之目的旨在探討鹽分逆境對四種台灣原生闊葉樹種-大葉山欖、水黃皮、福木
及樹青之危害及生理影響,研究內容可分為兩部分,其一為土壤鹽分及噴灑鹽沫對此四種
苗木之影響;其二以大葉山欖為例,探討土壤鹽分、噴灑鹽沫及機械傷害之影響。 有
關土壤鹽分及噴灑鹽沫部分,研究結果顯示來自於土壤鹽分對苗木之危害遠大於噴灑鹽沫
處理者,即土壤鹽分為危害苗木之主要原因,處理後隨著Na+、Cl-在植體累積,會誘導脯
胺酸之積聚,且Na+/Ca2+及Na+/K+比值亦會隨之增加,但葉綠素卻會明顯地受到抑制,其
他介量如T/R率、苗高及地徑生長等則隨樹種之不同而異,樹青之T/R率會受土壤鹽分處理
而產生顯著差異,大葉山欖之苗高及地徑生長皆會隨土壤鹽分處理而受抑制,水黃皮則僅
地徑生長受土壤鹽分處理之影響較明顯。 由相關分析所得之結果顯示,四種樹種Na+
、Cl-之相關係數高達0.90以上,且Na+、Cl-及脯胺酸之相關係數亦高達0.90以上。以大
葉山欖為例探討土壤鹽分、噴灑鹽沫及機械傷害之影響所得之結果顯示,機械傷害會抑制
地徑生長,且機械傷害及鹽沫處理會促進 Na+進入葉部之量,造成 Na+的累積效應。本研
究所得之結果將可提供做為植物於鹽分逆境下反應之基礎資訊。
The object of this study is to observe the physiological influences and
damages by salt stress to four native broad-leaved species, namely Palaquium
formosanum, Pongamia pingamia, Garcinia spicata and Planchonella pinnata. This
study were discussed (1)flooding salt water and salt spray effects in four
native broad-leaved species. (2) flooding salt water, salt spray and machine
hurt in Palaquium formosanum.
The results show that in the parts of flooding salt water and salt spray,
most damage came from flooding salt water treatment. The damage increased with
increasing accumulation of Na+ and Cl-. When Na+ and Cl- content increased,
proline accumulation induced, Na+/Ca2+ and Na+/K+ ratio was increased, but
chloroplast content was decreased in four species. Parameters
of T/R ratio, stem
ground diameter and tree height growth are different in some species, like T/R
ratio are significance difference by salt flooding treatment in Planchonella
pinnata, both stem ground diameter and tree height growth were
decreased by salt
flooding treatment in Palaquium formosanum, stem ground diameter were decreased
by salt flooding treatment in Pongamia pingamia. In correction analysis, there
are height correction coefficient between Na+ and Cl- was more than 0.90,
between Na+,Cl- and proline was more than 0.90 in all species.
In salt flooding, salt spray and machine hurt treatment, we take Palaquium
formosanum species as an example, the results show that machine
hurt may inhibit
diameter growth. salt spray and machine hurt can increased Na+ and Cl- into
leaves.
The findings will provide basic information for plant response to salt
stress.
