very weird pollenation reaction for super auto

[Epic Genetics]

I first heard it from my biology professor-it was in the text book too. Yes even humidity will set it off and it dies real soon.
FYI- pollen lands on the pistula were necter activates it-water alone is enough but necter has sugar and other nutrents.If you activate with suger water ( very weak) then the pollen will live a little longer. A little tube comes out the pollen grain and enters the pistula-no pistula death is very quick. If you have a microscope you may be able to watch the pollen real time activate and the tuble come out and grow-did it years ago in college.
PS I'm having trouble with my super auto showing pollenation and seed formation. It may be that it has been fertilized but the pistula is holding the pollen DNA untill it is time to make seeds. Many plants do this- the seeds all form and ripen at the same time. Note that this the thread starts with pistulas that seems to react and at about 1/3 down the pistula the reaction stops-This jives with my botony education some plants do this lest hope that this is the case. My problem is it may have lead me to over pollenate-a few days to weeks and we will know.

huh , neat , never knew that , any ball park idea how long it takes before the pollen dies ?

peace

I am now getting some seed formation. Early pollenation sites have poor results so far, a few days will confirm. I learned that pollen takes it's time when it's not compeating with other grains for the flower-so heavy pollenation shows faster! I pollenated last night used alot of pollen, long dwell time-then I misted lightly so the wet pollen stayed on the flowers-then slow dryed. The pistulas can best be discribed as "fryed". This morning I needed a magnifying glass to tell, as new pistulas mask the pollenation. So pollenation too early had poor sucsess.

The life span of pollen has factors that inclued-species, strain, is it ph'd to a good ph or hostile-ect, ect, Some common pollen needs 15 minutes to pop a tuble others 45. the science experiment has you check every 3 minutes after it pops for 30 minutes. The question would be how long untill it may not be dead but it can't fertilize any more. To sure kill--wet then dry. Dead as soon as it drys.

I now have more time and observations. Early pollenation will result in fertility latter on-I killed many pistulas with the pollen grain's sperm still dormant in the pistil by feeling for seeds. My finger oils and salts seem to be the culpret-no calixes and a few seeds. Other early, but light pollenation had few-(but still a little more seeds)-but many unfertilized pistulas still there.

The agressive pollenation a few days ago took!!! The plant is old enough to start making seeds asap.
My advise is if you like--
I speeded things up by: Lowered the nitrogen and phos, kept the potassium high, gave it some dark time- the plant responded by progessing to the next life stage-seed formation. I still have time to do more pollenation, but now I know I'm allready seeded well enough.

Let us know how you fair.
