they were necrotic and
inhibitive to proliferation. Explant diameter and area at
higher (9%) concentrations of sucrose in the medium
were significantly (P ≤ 0.01) inhibited (Figure 2a). These
observations are in agreement with those of Selles et al.
(1997) and Barpete et al. (2014b), who observed that high
sucrose levels stressed the shoots, which exhibited reduced
green leaves and poor development in Narcissus confusus
and Lathyrus sativus, respectively.
