The explants (root tip, shoot tip, stem segments and leaf segments) from Phalaenopsis hybrid were used in this experiment. The effects of NAA, 6-BA, AC, CM and above explants on callus induction on KC medium were investigated by using orthogonal design (L16(54)). The results indicated that the optimum medium for callus induction is 6-BA 4.0 mg/L+ NAA 0.4 mg/+CM 100 ml/L+AC 0.4 mg/L, and stem segment...
The distribution of lead in root tips of Dianthus carthusianorum was compared in populations from a zinc-lead waste heap in Bolesław near Olkusz and from a natural stand in the Botanical Garden in Lublin. The analyses were made at two developmental stages: seedlings (after 8 days of incubation in 5 mg/dm3 Pb+2 from PbCl2 in 1/8 Knop medium) and mature plants (after 23 days of incubation in 10 mg/dm3...
