Abstract：In order to investigate the suitable substrate water content in the hardening period during storage
and transportation of pepper（Capsicum annuum L. ） seedlings，this experiment studied the effects of relative
water contents in different substrates（ 25%-35%，40%-50%，55%-65% and 70%-80%） in the hardening
period on the change rule of main morphological and physiological indices of pepper seedlings under different
storage time periods（ 0，2，4，6 d），and the recovery ability of pepper seedlings after transplanting．The results
show that for short term（ 2 d） storage，the appropriate relative water contents of substrate for seedlings during
hardening period has a wide range（ 40%-80%）．For medium-term（ 4 d） and long-term（ 6 d） storage，the
suitable relative water content in substrate should be controlled between 70% to 80% during the hardening period
．The results of correlation and path analyses suggest that the single index suitable for evaluating pepper seedling
quality during storage and transportation is leaf integrity index，while the composite index is the stem diameter +
2.723 leaf chlorophyll content -1.235 root dry weight．
