Ecological Study on the Seed Germination and Emergence of Overwintered Stump of Bulrush(Scirpus juncoides Roxb.)
올챙고랭이(Scirpus juncoides Roxb.) 종자발아(種子發芽) 및 월동(越冬) 주기부(株基部)의 출아생태(出芽生態)에 관한 연구(硏究)
Abstract
To know the ecological pattern of bulrush (Scirpus juncoides Roxb.) seeds and overwintreed stumps in germination and sprouting responses as affected by different temperature (7 trt.), light intensity (5 trt.), shading intensity (S trt.), light quality (specturm spectrum; 6 trt.), soil acidity (7 trt.), stump sizea (weight base; 5 trt.), and molding depth (6trt.), respectively, this serial studies were conducted by use of growth chamber, incubator, Wagner pot and petri-dish. Most efficient treatment was obtained from 25-
올챙고랭이의 종실(種實)과 월동주기부(越冬株基部)의 발아(출아)(發芽(出芽)) 습성(習性)을 파악(把握)하기 위하여 포장조건(圃場條件)과 생장상(生長床), 항온기(恒溫器)에서 petridish와 pot를 이용한 일련의 환경요인처리반응(環境要因處理反應)을 조사하였으나 환경요인(環境要因) 처리(處理)는 온도(溫度) 7처리(處理), 광유무(光有無) 및 광량(光量) 5처리(處理), 광엽조건(廣葉條件) 5처리, 광질(光質)(spectrum) 6처리(處理), 토양산도(土壤酸度) 7처리(處理), 주기부중량(株基部重量) 5종(種), 산소농도(酸素濃度) 5처리(處理), 수분조건(水分條件) 6처리(處理) 및 복토심(覆土深) 6 처리(處理)를 하였다. 결과를 요약(要約)하면 다음과 같다. 1. 온도조건(溫度條件) (1) 종실발아적온(種實發芽適溫)은
