GERMINATION OF RED CLOVER SEED (cv. VIOLA) DEPENDING ON WATER SOLUTION pH AND SEED AGE

Utjecaj različitih pH vrijednosti vodene otopine (4, 5, 6 i 7) na energiju klijanja, klijanje, dužinu korijena, hipokotila i ukupnu dužinu klijanaca crvene djeteline istraživan je kod kultivara Viola skladištenoga 3 i 5 godina. Prosječna dužina klijanaca i hipokotila bila je najveća na pH 4, a korijena na pH 5. Prosječna energija klijanja bila je najniža na pH 6, a klijavost na pH 6 i 7. Energija klijanja i klijavost sjemena te dužina korijena klijanaca bili su veći kod sjemena staroga 3 godine, a dužina hipokotila, kao i ukupna dužina klijanaca kod sjemena starog 5 godinaThe influence of various water solution pH (4, 5, 6 and 7) on germination energy and germination of red clover cultivar Viola seed stored for 3 and 5 years, and radicle, hypocotyls and total seedling length was investigated. The highest average seedling and hypocotyls length was found at pH 4, and the highest radicle length at pH 5. The lowest average germination energy was estimated at pH 6, and the lowest germination at pH 6 and 7. Germination energy, seed germination and radicle length were higher in the 3 years old seed. Length of hypocotyls and total seedling length were higher in the 5 years old seed
