Microsporogenesis in vivo and in vitro. Autofluorescence of pollen wall of Lilium and changes in pollen wall of Gasteria in Lilium anther

M. T. Willemse

Abstract


Autafluarescence of the pollen wall of Lilium shows a correlative change with its development. When the pollen of Gasteria is injected into the anther of Lilium, it exhibits almost the same characteristics of wall autofluorescence as those of Lilium. Only the last stages of wall development are dissimilar. During this period the pollenkitt sticks to the pollen wall in Lilium only. The conclusion is that in the exine of Gasteria pollen, in contact with the locular fluid of Lilium, polymerization of Lilium sporapollenin occurs instead of a structural addition to the wall. This polymerization is a continuous process during the entire development.
