Visual Symptoms:
Initially, the plants developed slight stunting in their growth habits when compared to the control. Upon closer inspection, the stunting proliferated from the growing tips of the B-deficient plants. The growing tips and newer foliage displayed a distorted growth pattern. The new and expanding leaflets were smaller and narrower at the leaflet base when compared to the tip. In advanced symptoms, the new and expanding leaves displayed severe distortion. The leaflet margins became necrotic, and the leaves distorted severely, curling inward and down as well as at odd angles from the petiole. In the most advanced stages, the growing tips died and became necrotic, and the whole plant showed severe wilting due to the death of the root tips and subsequent loss of root biomass (Cockson et al., 2019).
