查询词典 tetraploid

The spikes per plant of diploid and tetraploidspecies were higher, but the kernels per spike, 1000 kernels weight and grain yield werelower than those of hexaploid and octoploid species. The NYE, NHI and NPE of diploidand tetraploid were lower; NDE was higher than these of Hexaploid. Variation of NPE andNYE was higher than other NUE indexes, which indicated that NPE and NYE could beused as indexes for NUE differences in different wheat related species.
