I spent a good 20 minutes scouring the Internet recently, looking for a reference, but gave up and went back to NEI. NEI is accurate and has the info, you just have to browse around (miss and miss and hit and miss) to find what you need. It's there, it's just not quick.
Start with an NEI look at the Mahoe sapling and at the Plum and Lemon saplings, then go backwards from there through their breeding trees (again, using NEI to assist). You *should* find everything you need to make a high-quality sapling by following their respective breeding trees (no pun intended).
Another way of using NEI is browsing everything that makes fruit juice and biomass in a squeezer. It will show all the sapling/fruit variants and how much fruit juice or biomass each piece of fruit or sapling makes in a squeezer. Lemon is something like 0.400 buckets and I forget what Mahoe is, but it's the most biomass per sapling.
