Comparison of Germination Characteristics and Daily Seed Germinating Pattern in Fine-textured Fescues Grown Under Alternative and Natural Conditions at the Room Temperature

Abstract

ABSTRACT. The study was conducted to investigate early establishment characteristics and germination pattern of fine-textured fescues (FF) under natural room temperature and to analyze differences between alternative and natural conditions for a practical application. Six cultivars from Chewings fescue (CF), creeping red fescue (CRF), hard fescue (HF) and sheep fescue (SF) were evaluated in the study. Daily and cumulative germination pattern were measured and analyzed. Significant differences were greatly observed in germination pattern, days to the first germination, days to 60% germination, and germination percentage with environments, species and cultivars. Final germination rate was 29.7 to 80.0% under natural conditions. The first germination was initiated between 8 and 10 DAS (days after seeding) under natural conditions, being 3 to 4 days later as compared with ISTA conditions. Days to the 60% germination were 12.1 to 19.0 DAS, being 3.0 to 4.2 days slower than that under ISTA conditions. CF 'Jamestown II' was the fastest cultivar, while the slowest CRF 'Audubon'. Turf establishment speed was faster with CRF < SF < HF and < CF in order. Information on differences in germination characteristics and pattern between alternative and natural conditions would be practically useful for a golf course construction etc., when established with FF.
