A new technique for estimating pollen viability utilizing Nitro Blue Tetrazolium (Nitro-BT) isgiven. Pollen of 16 taxa was studied and scored for stainability. A comparison was made betweenNitro-BT-stained pollen samples and aniline-blue-Iactophenol-stained samples, because thevalidity of the latter stain has been questioned in recent years. It is demonstrated that Nitro-BTcan discriminate between pollens which have a capacity for oxidative metabolism, representingpotential viability, and those which do not. Suggestions for pollen stainability studies are given. |
