On and on about netting!

Ah, the netting saga continues!!

I spent the day putting netting on a rootstock trial, as we use the fruit for teaching, and also winemaking. The trial has been very interesting, as the rootstocks were chosen to represent a wide range of rootstock grapevine species, and the control is Chardonnay (Mendoza clone) grafted onto itself, as the graft union probably has an effect on the growth of the vine as well. Unfortunately, we don't have an ungrafted control in the block, as there wasn't room to include it as an eighth treatment (six different rootstocks and the control grafted Chardonnay).

Still, there are intriguing results, with the scion (Chardonnay) trunk circumference to rootstock trunk circumference ratios being quite different among the treatments. Curiously, the Chardonnay grafted onto itself is not resulting in a 1:1 ratio, but is actually the smallest - the scion trunk circumference is the much less than the rootstock's trunk circumference, even though they are the same plant material!

In any case, the netting, which is single over-the-row type netting that I've already put photos up of, is over the vines, and the three rows mostly clipped up. The worst of the bird damage was at the end of the rows that are closest to the Poplar tree windbreak. This is one of the reasons that viticulturists don't like having trees near the vineyard - they provide roosting areas and cover for birds!
