Abstract/Contents:"An experiment was conducted on four Italian ryegrass (Lolium multiflorum) seed lots using two methods (germination between rolled-papers and emergence in soil-filled-trays at 13 and 20°C) to determine whether mean just germination time (MJGT) and mean germination time (MGT) could be used to evaluate vigour and predict seedling emergence potential in soil. MJGT and MGT were found to be positively related to mean emergence time (MET) and variation of mean shoot length (CV), and negatively related to emergence rate (ER) and mean shoot length (MSL). Lot 4, with the shortest MJGT and MGT, emerged most rapidly and with the shortest MET and highest ER. In contrast, lot 1, with the longest MJGT and MGT, showed slower seedling emergence and with larger MET, presented the smaller and more variable seedlings. Furthermore, there was a positive linear relationship of MGT between 13 and 20°C. Thus, MGT at 20°C could be used to predict seedling emergence and growth of Italian ryegrass seeds."
