Title: Re: [NAFEX] Grape - internode length Internode length is a function of environment rather than the particular vine. If you look at shoots, usually there will be one or two extra long ones about the third to fifth node out from the base. That reflects a period in early summer when conditions were ideal and the vine put lots of extra vigor into it. If you are trying to select a more vigorous vine, you are more apt to succeed if you keep records and select the vine with the greatest overall vigor AND productivity, as measured by both the amount of wood and fruit it produces. Individual shoots that are more vigorous might have a slight edge over others on the same vine, if they have received extra food and are healthy and well matured, but usually they are just "bull" canes that are oversize and harder to handle, without giving any better results. The absolute best part of the cane is the first foot or so, where the wood is more mature and has more nodes for the length than the rest of the shoot.

Subject: [NAFEX] Grape - internode length
Hello All,
After reading the article on grape grafting in Pomona again I thought I
would give it a try, to see if I could do it. Looking at the various
variety vine internode lengths, it got me thinking...
Is there a relationship between the length of the internode between
grape buds that correlates to how vigorous a particular vine will be?
For example there are more and less vigorous Concord grape vines. Will
the average internode length be the same on both vines, or will there be
a shorter internode on the less vigorous vine?
Also, is there a way to determine average seasonal growth of a vine (new
wood) based on average internode length of a vine?
Thanks,
Tom
