Summary
-
1.
The pairing of the single leptotene-threads inCanna glauca “pure yellow” is evident.
-
2.
A new split (the aequation-split) is in favourable cases already visible in the pachytene-stage.
-
3.
A greater portion of the pollen mother cells, after having reached the diplotene-stage, perishes (before diakinesis); the causes are not to be ascertained.
-
4.
Abnormalities in metaphase I are very seldom found (partly double or forked spindles).
-
5.
The pollen is formed by normal divisions; the irregularity in prophase has no influence whatever on the formation of the pollen.
