Scientific Observations of Environmental Stress on Pepper Varieties

24 January 2017 - 03:22 PM

In response to solid7, "You're the overzealous master of link posting, about things, and for the sake of.  Feel free to find it, and repost it, yourself.  If you can find an animated gif of Obama sitting on a crate yawning, you should have no problem finding a study that I linked to.", my response is - others with much more resources than any gardener has in his backyard and a single link posted I don't know when or where it came from, I'll take the links to well funded research by organizations that are internationally respected. Unlike those whose single mindedness is of their own observations with closed acceptance to widely accepted research I did due diligence and looked for and found it is a complex combination of many things but genetics, amount of stress, type of stress, and when applied can and caused slight decrease - no change - to substantial increase.... 


Aerican Society for Horticultural Science/Impact of Drought Stress on the Accumulation of Capsaicinoids in Capsicum Cultivars with Different Initial Capsaicinoid Levels
 
"In conclusion, capsaicinoid levels increased for all cultivars studied when subjected to drought stress, except for the cultivars in the high pungency group. A yield response under drought stress for the medium pungency group varied and was not found to be associated with drought stress."

American Society for Horticultural Science/Water Deficit Affects the Accumulation of Capsaicinoids in Fruits of Capsicum chinense Jacq.

"Habanero pepper plants under water stress had a lower height, root dry weight, and root/shoot relation than control plants, which were irrigated daily. However, fruit growth and production were unaffected by water stress. Capsaicin and dihydrocapsaicin concentrations increased in fruits of stressed plants compared with control plants, and this effect was correlated with fruit age. "
 
 
MDPI/Characterization of Different Capsicum Varieties by Evaluation of Their Capsaicinoids Content by High Performance Liquid Chromatography, Determination of Pungency and Effect of High Temperature
 
"High temperatures can be a negative factor in the accumulation of capsaicinoids in certain varieties
of chili peppers, this study showed that the varieties most affected were Jalapeño and De árbol peppers
as they lose 61.5% and 32.5% of total capsaicinoids, respectively. Moreover, the temperature rise in
greenhouse favored the accumulation of total capsaicinoids in varieties Guajillo and Serrano and
corresponding to an increase 3-fold. Furthermore, the Puya variety showed a slight increase of 21% in
the amount of total capsaicinoids; while having a slightly positive effect on Ancho with an increase of
8.6%. These data demonstrate that the responses of the peppers did not show a homogeneous behavior.
In literature it has been reported that levels of capsaicinoids increase in spicy peppers varieties more
than in sweet peppers when the temperature rises in the place where cultivated, however, our results
show a decrease in the amount of capsaicinoids in Jalapeño and De árbol varieties. "
 
Some like it hotter: UC Cooperative Extension tries to grow a spicier jalapeño

"Research studies in Mexico, Taiwan, Thailand and Spain have shown that water stress results in hotter peppers so Sanders and Baameur tried irrigating with less water. For us, it did not show that, Baameur said. We sampled fruit and we analyzed it for capsaicin content, which makes a pepper hot. It was fairly low, actually it was almost half of what the normal treatment, or control, would be.

The relatively cooler climate of the Santa Clara County area may be the reason the pepper plants produce different results. I think it's more a relation to heat, ambient temperature, much more than just water, Baameur said. Cool years and hot years will result in different heat units for the same jalapeño variety.[/size]
 
My conclusion is different influences have different results at different times but generally environmental stress has an influence on the pungency of peppers, YMMV.

Lazy Man Vermicomposting

14 January 2017 - 04:08 PM

I thought I'd pass this on for those who are not into doing it under the kitchen sink.> Vermicomposting - Composting with Worms

This is a concrete platform  behind my home that has landscape retaining walls on two sides (I also have a driveway that I use in a similar fashion.). This is a two season plan, one spring I harvest then mother nature supplies the worm food, the wall remains fallow until the following spring when I harvest and the two year cycle starts over again, alternating sides for harvesting.  Got it?

Five Year Old Potting Soil Rejuvenation

03 December 2016 - 01:24 PM

PS. I use buckets & recycle the potting media.............
 
LineUp1_45_Trimmed_zpsurwg4xvg.png


 
I was asked in a PM by Masher what "process" I used to rejuvenate old potting media. I did this for another pepper forum so re-posting here was easy to reproduce and I thought others might be interested. The basics are... 5 gal. pail with 20 or so 3/8" holes for drainage, 2" layer of pea stones, landscape fabric to segregate media from stones (And make it easier to remove media for rejuvenation when necessary.) and products listed in instructions. Ready?

This is the pot with 5 year old "fallow/compacted" media.

Note 6-8" gap from rim where media was originally..
 
 
 Rebuild2_zpsw1tmouna.jpg
 
 
Grab the landscape fabric, yank it out of the pail and placed in wheelbarrow.

 Last time it was Serrano, note how faded the plant marker is.

Note liner prevents media from mixing with stones and plugging drain holes.

Separate the landscape fabric from the compacted media.

The media is so compacted it looks like mud!

 

 

Rebuild6a_zpsbdpaa3yn.jpg

 

 

 

Bring on rejuvenation materials, new commercial potting media,

 

 

 

Rebuild8_zpskfu9ajsg.jpg

 

 

Some good quality compost,



Rebuild7_zps4dpred54.jpg

 

 

Don't forget peat moss.

I usually mix them up at this point for easier progress on smaller additives.
Mix rates I used was pail of old compacted media - 1/3 each of new media.




Rebuild9_zpsyicxb6q4.jpg


Now perlite.


Rebuild10_zpsxbp4n9dd.jpg

 

 

 

And additional time release ferts!

 

 

 

Rebuild14_zpsfewk9aif.jpg

 

 

 

Mix it all up....

 

 

 

Rebuild15_zpsbmntkzdy.jpg

 

 

 
Put the landscape fabric back in the pail.

 

 

 

 

Rebuild16_zpsfbv3rbux.jpg


Fill pail with rebuilt media, lightly tamp on hard surface to mildly compact.

 

 

 

Rebuild17_zpsgggndp9n.jpg

 

 

 

Pot up your pepper plants as you normally would.

 


Another question asked was the root mass in the media which was not present in this fallow rejuvenation. Basically, when you yank the landscape fabric filled media and empty it in the wheelbarrow the media/root ball are easy to separate and any  smaller root debris I leave in media to compost.

Hope this helps!
