Growth and Mycorrhizal Formation of Pinus thunbergii Seedlings Grown in Growth Chamber

Growth Chamber 내(內)에서 생육(生育)한 해송묘(海松苗)의 생장(生長)과 균근형성(菌根形成)

This study was carried out to indentify the mycorrhizal development and growth stimulation of Pinus thunbergii seedlings grown on soil growth media which mixed with various amounts of pine bark. The results were follow ; 1. Seedlings inoculated with Pisolithus tinctorius were significantly increased in number of short roots and mycorrhizal short roots, height, maximum growth rate, and leaf area than those of no-inoculation. 2. Mycorrhizal formation according to bark contents was highest by 25% bark treatment, and decreased in 50 and 75% bark contents. 3. Within the same treatment of bark content, seedlings inoculated with Pisolithus tinctorius showed more increased height and leaf, stem, and root dry weight than those of no-inoculated.

본(本) 실험(實驗)은 송피함량(松皮含量)을 달리한 배양토(培養土) 0, 25, 50, 75%에 균근균(菌根菌)을 접종(接種)하여 처리(處理)에 따른 균근형성(菌根形成) 및 식물생장(植物生長)에 미치는 영향(影響)을 구명(究明)코자 실시(實施)되었으며 결과(結果)는 다음과 같다. 1. 균근(菌根) 접종묘(接種苗)가 비접종묘(非接種苗)에 비(比)해 세근(細根), 균근수(菌根數), 개체생장율(個體生長率), 엽면적(葉面積) 및 묘고(苗高)가 증가(增加)하였다. 2. 송피함량(松皮含量)에 따른 균근형성율(菌根形成率)은 25%구(區)가 높았으며 50% 및 70%구(區)에서는 감소(減少)하였다. 3. 동일송피(同一松皮) 함량구(含量區)에서는 균근접종구(菌根接種區)가 무접종구(無接種區)보다 묘고(苗高) 및 엽(葉), 경(莖), 근건중(根乾重)이 증가(增加)하였다.
