Using a Scanner-based Minirhizotron System to Characterize Sweetpotato Adventitious Root Development during the Initial Storage Root Bulking Stage

摘要: A scanner-based minirhizotron (MR) system detected initial adventitious root dvplonment associated with transplant establishment. The also docu(AR) development documented the transition of ARs into pencil roots (PRs) and, in some cases, storage (SRs). In general, MR underestimated destructive sampling-based (DS) estimates newly initiated AR (NAR), PR, and SR counts. Angled or vertical single sampling tubes NAR count by 85% 79%, respectively. Regardless installation position, tube-based measurements PR 83% 95%, However, it was found that two vertically installed only 48%. potential ability paired to discriminate differences response experimental treatments confirmed a simple rain shelter experiment. DS systems 56% reduction among plots shelters, appeared presence interfered formation monitored segments. Despite this limitation, results show for incorporating ongoing future studies aim qualitatively quantitatively document sweetpotato agroclimatic variables management interventions during bulking stage.
