The exine of Anigozanthos viridis Endl. pollen is divided into two zones by a plane which has been referred to as a"commissural line"; in our results we refer to it as a junction plane - a more apt description. Following young stages there is a prono

In Pinus sylvestris Ubisch bodies are produced repeatedly, and each crop is formed at a distinct phase in the secretory cycles of tapetal cells. While each production has a Ubisch body wall similar to the then current state of the exine with regard t

Compositae exhibit some of the most complex and diverse pollen grains in flowering plants. This paper reviews the evolutionary and developmental origins of this diversity in pollen structure using recent models based on the behaviour of colloids and

This article is a review of research and accumulated information about connective structures between, respectively, microspores in the locular space in anthers of angiospermis and the spores in the megasporangia of Lycophyta, as well as a comparison

The exine of mature pollen grains of Rhoiptelea chiliantha was studied. The size of the pollen grains is about 23 by 27 μm. They are tricolporate with short colpi that are 1-2 μm wide and 10-12 long. The spinules of Rhoiptelea are similar in form a

Tapetal cells of Pinus sylvesiris L. underwent one hypersecretory cycle during early pachytene and entered a second cycle by the time of mid pachytene in microspore mother cells. Initially in each cycle tapetal cells became papillaform then dome-shap
