Figure 4. Effects of D-pinitol and D-glucose on the growth of L. procerum, RTB larva, and the most frequently isolated bacterial strains.

(a) The linear growth rate of L. procerum on the media which contained only D-pinitol or D-glucose as carbon source respectively (growth rate, mm/d, +s.e.m., n = 9 for each treatment). (b) Weight change of larvae feeding on phloem media containing D-pinitol or D-glucose respectively (weight change, mg, +s.e.m., n = 56 for each treatment). (c) The growth of the most frequently isolated bacterial strains in liquid cultures which contained D-pinitol or D-glucose respectively (OD₆₀₀, +s.e.m., n = 3 for each treatment). “*” between the two connected bars referred to significant difference.
