M. Kwiatkowska et al., Effect of GA(3) treatment on the number of spermatozoids and endopolyploidy levels of non-generative cells in antheridia of Chara vulgaris L., PLANT CEL P, 39(12), 1998, pp. 1388-1390
The youngest nodes located under an apical bud of Chara vulgaris were isola
ted and cultivated in the presence or absence of 10(-5) M GA(3) under labor
atory conditions to form spermatozoids. GA(3) increased the DNA C-value in
manubria by 20% and increased the number of spermatozoids per antheridium o
ver 2-fold.
