Re: CULT: Bloom stalk question

Hello, Paul.?

This phenomenon?was discussed in the May,?2006 postings, found in the Archives. I raised the subject, and called it Shriveled Stem Anomaly, although I'm certainly not wedded to the term. I also referenced cooked green beans as a?metaphor.

I had a couple of private responses to my posts in 2006, including one from a prominent iris grower, and there was no indication that there was any established term to refer to the condition. 
Its an odd one. I saw a whole clump of Seminole, in heavy bud, with the limp?stems.?Clearly a?failure of turgidity, which in itself suggests several?coarsely amusant terms,?all entirely unsuitable for the ears of the respectable.

Subject: [iris] Bloom stalk question

Does anyone know if there is a technical (or correct) term for what happens to 
the bloom stalks when they shrivel in the area between the fan and buds?  I 
pretty much know what causes it.  It usually happens when it gets very warm and 
sunny after 3-4 days of cloudy and usually rainy weather.  I'm thinking the 
stalks are just not hardened off enough during a critical stage of development 
that 3-4 days with little sunlight.  Sometimes some varieties get "snakey" as 
well but those don't seem to have the shriveling problem.  That usually happens 
(if not always) on the ones that are staight up only to have them collapse in 
the middle of the stalk.  The buds look fine and we haven't had any frosts or 
freezes.  This happens every year on some varieties when this type of weather 

I'm also thinking we could be selecting varieties during the breeding process 
that don't do this.  Tht goes for the snakey tendency as well.
