Effect of temperature and moisture potential on germination and emergence in Lotus sp

摘要: Two controlled cabinet experiments compared the germination of 6 Lotus genotypes over a range temperature (0-40¦C) and moisture potentials (0 to -1.2 MPa). A field experiment emergence 5 18 sowing dates. cornzculatus cv. Grasslands Goldie. L. uliginosus, Maku, G4703, G4704. Sharnae were included in both experiments. suaveolens CPI 35903 was only Trifolium repens Haifa as control study. Of commercially available cultivars, Goldie provides greatest flexibility terms date coastal New South Wales could be successfully sown even late autumn winter it had lowest base for emergence. Sharnae, G4704 lower potential than other 3 but this not translated better an extremely low (l¦C) with uliginosus Maku (6.4¦C). Hybridisation species corniculatus result germplasm capable germinating at still able maintain perenniality, rhizomatous habit, presence condensed tannin uliginosus.
