摘      要：The ability to screen larger populations with fewer replicates and non-destructive measurements is one advantage of high-throughput phenotyping(HTP)over traditinal phenotyping *** this study,two wheat accessions were grown in a controlled-environment with a moderate drought imposed from stem elongation to ***-green-blue(RGB)imaging was performed on 17 of the 22 d following the start of drought *** measurements from all plants were performed at the conclusion of the *** effect of line was signifcant for shoot dry matter,spike dry matter,root dry matter,and tller number,while the water treatment was significant on shoot dry matter and root dry *** temporal,non-destructive nature of HTP allowed the drought treatment to be significantly differentiated from the well-watered treatment after 6 d in a line from Argentina and 9 d in a line from *** difference of 3 d indicated an increased degree of drought tolerance in the line from ***,HTP from the final day of imaging accurately predicted reference plant height(r=1),shoot dry matter(r=0.95)and tller number(r=0.91).This experiment ilustrates the potential of HTP and its use in modeling plant growth and development.
