You have to remember that for photosysthesis to take place every thing has to line up. Plants can take differing amounts of heat/sun. When they get too much or they start to dry out too much they start to close their stomata. Then it's sort of like a truck stopped in the middle of the road, the rest of the traffic gets backed up behind and stops. So with the plant, water stops passing up from the roots, nutrients stop moving up through the plant, there's no exchange of carbon dioxide and oxygen with the atmosphere so photosynthesis ceases. IE. no growth.
My "monster" Konjack SHRUNK!
yeppers.. tropic.. i was trying to make sense of my amorphs..and how they're doing..
which is great!! :) they may be "shorter" than if they were in somewhat shaded area ..for more of
the day.. but..if the corms get huge .. i dont care.. :)
?? for konjac..what should i expect a "normal" height of the vegetative stalk?
my pre flowering corms of 9 #s are now 34" tall above soil level.. with widest girth of stalk
shy of 5 "..?? what do u all think??
?? i guess theres no way to tell about the corm until i take them out of soil/ or pots..
the leaves are great..the vegetative stalks have all grown in girth..
im thinking this is a good sign..??
it is a balance.. soil..soil type,drainage,lack of drainage,fertilizer,sun,how much sun..
im always on the hunt for new/better info on how to make my plants HAPPY CAMPERS !!
:)
much thanks.. love these amorphs!!!!
Sorry, I was looking for the pdf. so I could just send it, but I can't seem to lay hands on it.
Here's a brief synopsis of one of the papers
http://agris.fao.org/agris-search/search/display.do?f=1989/KR/KR89005.xml;KR8835822
Here's one brief reference to it in NZ:

http://agris.fao.org/agris-search/search/display.do?f=1986%2FJP%2FJP86024.xml%3BJP8505370
The other odd bit of data was on pot sizes and numbers of tubers per pot - yeilds were higher with more than one tuber per pot - I'll see if I can find it later...

Alrighty, My largest Konjac is open! 2 smaller ones getting there next to it.
looks really good tommy!! :) arent they facinating plants..
from a big lumpy corm,sending out a stinky weird flower,then their
beautiful fern/palm like leaves..
hows your weather in poughkeepsie? were having a HOTTTTTT spell..
im saying spell..hoping that we'll get some relief.. sigh..
Having a heat wave here. 94 today, hotter yesterday. The second heat wave of the season.
Highest according to my Davis Vantage Vue weather station so far this year is is 99.
again much thanks vestia..
my take on the 2010 indonesia study on A.muelleri..
1. water limitations affect muelleri going into an early dormancy
2. available rooting material - soil.. limited soil probable connection
to limiting available water..and causing stress to roots..therefore limiting the growth
of the leafing,and corm..
i thought it was also a good observation reference to the Hetterscheid & ittenbotch
study.. the two groupings of amorphs and their respective ecological origins.. and the climate/wet/dry
seasons of those areas..
its like being in college again... love it!! :)
the more i learn about these beauties..hopefully the better i am at keeping them.
good stuff !!!
you're welcome.
In response to what I've read, I'm trying out very large self-watering pots to see if that will reduce any drought-stress.
Also, several of the pots are planted with two tubers per pot.
Will report here if I can observe any differences from previous years.
thanks vestia..ive been thinking of trying some of the pots developed by aroids.org..
if i understand correctly..they are a meshlike ..all sides porus..
i dont have problem as yet with any of my amorphs..but i was thinking with titanum,hewitti..and if i can
get gigus,and decus-silvae.. those type "porus" pots might be helpful to avoid having to wet a soil..
but then otherside of it is.. im sure i'll have to water more often.. LOL
good luck to you..and hope to see how youre doing !! :)
