Description
Jiahua Du and co-authors used deep cold to make double pollen in poplar trees in a 2026 study. Double pollen has twice the gene set, and crosses with it give trees with three sets. Such trees can grow fast and strong, a prize for wood and paper work.
Cold snaps broke the last split step in male cells, which left the gene set whole. Stage of growth, cold depth, and cold span each swayed the yield. The best run froze buds at one set stage for five hours and got double pollen in near one in three grains. Crosses with the pollen gave 26 three-set young trees.
