“…There is no evidence at any time of contacts between tapetal cytoplasm and the surface of the grains. This is in contrast with the situation in Galanthus nivalis, where the PoUenkitt is synthesized by an invasive tapetum, the cells of which are in intimate ass(jciation with the young spores (Pankow, 1957). Evidently in Galanthus, cytoplasm, or cytoplasmic products other than the PoUenkitt itself, could be transferred and trapped in ca\ ities within the exine in the mantier proposed by Pankow.…”

“…Pankow, 1957), namely, that the synthesis must be programmed by the parental genome, and not by the haploid spores themselves. Thus where the colotir of pollen is due to surface materials of the nature of Pollenkitt, it is determined by sporophyte tissues external to the spores.…”

“…The material is present in particular abundance in animal-pollinated grains where it has been termed Pollenkitt (PANKOW 1957) and in other cases tryphine (see review by ECHLIN 1971). Because of this cOnfusion in terminology, the term pollen-coat suggested by ZANDONELLA et al (1981) has been used in this chapter.…”

“…Shortly after dehiscence of the mature anthers globules are deposited in the ectexine. This material, the degradation product of the tapetum, has been identified as lipidic in nature (Pacini & Casadoro, 1981) and is analogous to the so-called pollenkitt (Pankow, 1957) found in most mature pollen grains, both entomophilic and anemophilic. (1982) Figure 7.…”
