This sage mode could be related to the god tree, as the god tree is said to be mainly natural energy and wood release is related the god tree in some way. I kind of doubt it. More than his wood release, if his body also somehow gave instant Sage Mode then it would've been mentioned (and insanely OP). It's clearly a learned technique, the question is how he learned it. He's not connected to snakes or toads, so it can't be those (and his mode doesn't look like those). His granddaughter summons slugs, so it could be a Slug Sage Mode. Son Goku also implies there's Sage Monkeys, so it could also be connected via Sarutobi.
