3.2. Light
Sensitivity to light in relation to onset of germination and final germination percentage of the eight vegetable species is presented in Table 2, which also lists their 100 seed weight. Positive effects of light on the onset of germination were recorded for B. rapa subsp. chinensis, A. cruentus and C. olitorius, and negative effects for C. lanatus and V. unguiculata. For B. rapa subsp. chinensis the positive effect of light was significant (p ˂ 0.01) throughout the incubation period, and in C. lanatus and S. retroflexum exposure of the seed to light increased final percentage germination significantly (p ˂ 0.01). Light did not have a significant effect on the final germination percentage of A. cruentus, C. gynandra, C. olitorius, C. maxima and V. unguiculata, but this effect tended to be positive for all of these species except V. unguiculata.
