No idea, but Yamato said it's Naruto's life force doing that in the very chapter, it was never attributed to Kurama or Yang bs for that matter. For all we know, Minato with Yin Kurama's chakra standing next to plant would make it grow too, or perhaps it wouldn't, but not because he had Yin instead of Yang, but because his life force wasn't strong enough.

EDIT: then Kurama's life force as well it may be, but life force isn't Yang.
