Their fertilizing capacity develops as they pass through the epididymis (Young, 1931; Nishikawa and Waide, 1952; Blandau and Rumery, 1964; Bedford, 1966; Orgebin-Crist, 1967). This

As most frequently reported (and described here), meiosis in plants involves a single diploid nucleus with its DNA in the replicated state dividing twice, without further complete
