| Abstract/Contents: | Reasons for the uneven germination and establishment of Italian ryegrass seeds sown on hillsides after ploughing were investigated. When germination percentage was 80%, water absorption rate at 25 deg C was 79% in unhusked seed and 74% in husked seed. Even where maximum temperature during the daytime was 30 deg , uncovered seeds germinated well as long as the humidity at the soil surface was 90%, but germination was poor if the humidity was only 60-70%. Where soil clods were (5 mm in diam. seeds only germinated at high soil moisture levels. Where clods were 10-20 mm in diam. and the soil was dry, germination still occurred as seeds fell between the clods to moister soil below. F.en s. |
