Seeds were exposed to three levels of water supply regime (5·0, 7·5, 10·0 mm at 3-d intervals) and eight levels of burial depth (0·0, 0·5, 1·0, 1·5, 2·0, 3·0, 4·0, 6·0 cm). Each treatment had five replicates.
Different capital letters in every column indicates significant difference of final emergence percentage and emergence rate with same water supply. Different lower case letters in every row indicates significant difference of final germination percentage and emergence rate of different species with different water supply under the same sand burial, P < 0·05.
