AG Pollenation question / problem

wayne_perrier(z9 CA)June 18, 2005

I've got a single AG growing out in my backyard. The primary vine is about 13 feet long right now, growing about 6 inches per day. I'm watering 4 times a day, about 6 1/2 gallons of water per day total. Plant looks very healthy although some of the older leaves are yellowing. Lots of secondary vines; haven't had to prune much yet. On hot days here (85 degree), some of the larger leaves are wilting slightly but they recover in the evening. this only happens during the hottest part of the day and is the reason that my watering is spread out into 4 intervals.

Here's the problem. I pollenated two females over the last couple of weeks. On one, there was only one male flower available, so I used it; on the second one I used 2 male flowers. Both of these females have withered and died off over the last several days and never got over tennis ball size. I never taped the flowers closed after pollenation. There are lots of ants around, and they seem to like crawling into the flowers.

I pollenated another female today, about 11 feet out on the primary vine. I used 3 male flowers, and this time I taped the flower shut. I'm hopeful I'll be more successful this time.

Can anyone provide insight or opinions on what happened on the first two flowers ? I really thought that they'd "take". Thanks in advance.

Are you pollinating early in the morning, soon after the female opens? I think I heard/read there is only a few hour interval to make a successful pollination. You may have to get up at 5 AM, or so, on the day the female opens.
Also, hot days can cause the fruit to abort, I think. I don't think 85 would be too hot, but the ground temp. could be much higher. I remember in one of Don Langevin's books, someone put ice near a newly pollinated female, to cool the area.

Hi Douglas: the pollenation was at various times, none that early. I find the flowers not yet open super early. The one this morning had basically just fully opened at about 9:30, which is when I pollenated it. It was about 62 degrees this morning at that time. I've seen the ice pictures in Don's book but thought that that was a little over the top. Perhaps not. If this one doesn't take, I'm willing to try other techniques, fast, because I've probably only got a 14 day window for this (in 14 days the primary vine will be 20 feet long). thanks
