Will peach pollen cause almonds to be bitter? What I'm asking if a almond flower ovaries take on pollen from a nearby peach tree, will the almonds be bitter? Peach kernels are known to have a fair amount of cyanide, about 85% of what apricots have. I guess you could assume apricot could do this too? Since the almond kernel is a seed, half the genetics come from the pollen parent. So thinking they might be bitter, or not as good as another almond pollinating the ovaries.
