Spectral sensitivity of seed germination and seedling growth in amaranthus species


Bangladesh Journal of Botany 12(2): 171-177
Spectral sensitivity of seed germination and seedling growth in amaranthus species
The present study reveals the spectral sensitivity of seed germination and seedling growth in A. caudatus var. artopurpureus, A. tricolor (cultivated and wild forms) and A. viridis. Blue light was the most promotory for seed germination to the first 2 spp. while far-red in the last one. A great variation in seedling growth under different spectral regions was also noted in all these species. Total darkness enhanced both radicle and hypocotyl growth in A. caudatus var. artopurpureus and A. tricolor (cultivated form) whereas only hypocotyl growth was increased in A. tricolor (wild form) and A. viridis; however, radicle growth was inhibited under this light. Among the other spectral regions, red for A. caudatus var. artopurpureus and A. tricolor (cultivated and wild form) while far-red for A. viridis were found promotory for seedling growth.
