Comparative Sensitivity of Binucleate and Trinucleate Pollen to ultraviolet Radiation: A Theoretical Perspective

摘要: Angiosperm pollen shed in the binucleate condition (which is case for most species) may be more susceptible to UV radiation damage than trinucleate condition. This speculation supported by data summarized from literature which show that physiologically advanced at time when it anther. The course of germination, penetration stigma, and successful fertilization thus rapid these species. results less exposure solar ultraviolet consequently should expected. Experiments are needed test sensitivity types vivo evaluate efficacy possible repair mechanisms.
