The effect Gibberellins (Gib) have on a Sultana berry
On 29 November I shared with you the methods I use to cultivate top Sultana Grapes.
Numbers in above picture:
- shows you how the gib has stretched the berries - see that little dimple at the bottom of the berry? - they are gonna be huge berries in a few week! Without gib treatment, Sultana has a normal round berry, not big in size and very condensed bunches.
- look how the gib thinned out the bunches to make place for a bigger berry size - in a few weeks, these “gaps” will be filled and you will have a 700 gram bunch with berries of +-21 to 23 mm!
This picture was send by one of My-Grape-Vine friends - he has a lovely Sultana vine, but what I need you to look at, is the difference in berry shape and how compact these bunches are.
With bunches like this, you will probably have a reasonable crop, but you will never have that berry size that will let your neighbor say: WOW! Where did you buy that!
Secondly, controlling diseases in these condensed bunches is almost impossible - you will have a problem if your grapes get some disease.
Have a grape (great) day!
