Inhibiting Effects of Myrmicacin on Pollen Growth and Pollen Tube Mitosis

“…However, pollen source genotype interactions with various concentrations of nonionic surfactants added directly to the medium have been reported in maize (20). The effects of various pesticides on in vitro pollen germination of other species have been examined with similar depressions in germination and tube growth found (26)(27)(28). As indicated, only limited studies have been conducted using in vitro pollen germination as a biological assay to determine the physiological activity of some agents.…”

In vitro pollen germination was examined as a method to determine the mutagenic and physiological effects of environmental pollutants on higher organisms. Results were presented indicating that mutations could be distinguished by their in vitro germination characteristics if sporophytes homozygous for the mutated allele were tested. The addition of agents directly into the in vitro medium was shown to be an effective method to assess their physiological effects. The exposure of pollen grains during the in vitro germination process to ultraviolet radiation in the B range (280-320 nm) was found to produce little or no change in the germination or ruptured percentage but a sharp decrease in pollen tube growth after 1 hr. In vitro pollen germination appears to be a valuable method to examine the mutation types and physiological effects produced by a broad range of environmental pollutants. In fact, since in vitro germination is related to reproduction and gene transmission, the biological activity of these agents on in vitro germination should be tested routinely to determine their possible effects on food production and gene frequency changes in future generations.

“…This modification introduces difficulties in comparing concentrations since the germination of maize pollen grains requires a delicate gas-liquid interface (13) around the pollen grain which will be altered by drying procedure. The effects of various pesticides on in vitro pollen germination of other species have been examined with similar depressions in germination and tube growth found (26)(27)(28). Pollen source genotypes were included as part of this study (25) but their individual response patterns were not reported.…”
