Effects of sexual polyploidization on reproductive development in a full-sib poplar family

Comprehensive Overview of <i>Populus</i> <i>simonii</i> Research in the Recent Years

“…Research by Ma Hongwen [53] showed that although the stomatal density of triploid leaves is significantly smaller than that of diploid leaves, the chlorophyll content is significantly higher than that of diploid leaves, and the stomatal length and stomatal width are significantly greater than that of diploid leaves. It is worth mentioning that there is also research supporting that polyploidization will considerably reduce the viability of P. microphylla stamen pollen [54]. In terms of improving the stress tolerance of P. simonii, Xiao-Xiao Zhang [55] and Jian Wu [56] used colchicine to induce varieties with fast growth, easy cutting propagation, and tolerance to salt-alkali and drought.…”
