Subject: introduction
I would like to introduce myself as an Ornamental Horticulturist at the
Kuwait Institute for Scientific Research. We are interested in introducing
and naturalizing as many salt and heat tolerant ornamental plants as
possible for greenery development. Our other research interests include:
management of saline soils, use of brackish water and high salinity for
irrigation, production of halophytes, biosaline agriculture research, etc.
We were able to naturalize a few ornamental plants and generate preliminary
information on the use of brackish irrigation water. Some of the plants are
being extensively used in landscape projects in the country. I would like
to receive information/ discussions on the above mentioned topics.
Thank you

When the California State Water Project was initiated, the Department of
Fish and Game explored use of low-water consuming plants to provide greenery
and support wildlife use along the aqueduct. I read their reports many
years ago. They found several species of Atriplex in the Chenopodiaceae
which could germinate in moderately saline water, but survive in saltier
water. You may want to explore the use of shrubs in that plant family,
which is well distributed in arid areas worldwide. An herbaceous Chenopode
called New Zealand Spinach, (genus Tetragonia, I think) grows in California
on sandy shores along the beach. I have grown it in my garden. It is quite
palatable to me, and even somewhat ornamental. Seeds are sold in US
gardening catalogs, and it is easy to cultivate, but not frost-hardy. Other
plants that DFG found with high value for wildlife were legumes in the tree
and shrub genus Prosopis, commonly called mesquite. It is slightly less
salt-tolerant, however. I understand this plant has already been introduced
as a forage and fuelwood source in Africa. Mesquite beans are nutritious and
can be consumed by humans and livestock, while the wood is made into a
premium grade of charcoal in the western US and used for cooking because of
its aromatic flavor. Finally, some strains of barley and tomato have been
grown experimentally with sea water. An important constraint in growing
these salt-water tolerant strains is that a freely draining site is needed
and excess water must be applied to prevent salts from becoming concentrated
in the root zone. This quickly washes out soil fertility, so nutrients must
be added.

We just completed some salt tolerance trials on winter vegetables,
New Zealand Spinach being one. It was not as tolerant as Orach
which is a member of the Atriplex family. Kale is also very
tolerant and comes in decorator colors. Purslane is an extremely
tolerant plant and makes a delicious and nutrious salad with low
omega fatty acid contents!

Michael;
The Omega 3 and 6 fatty acids are essential and, in our haste to
get rid of fats, we throw the baby out with the bath water!

There is a very pretty ornamental purslane commonly called "Moss Rose", with
beautifully colored flowers. I believe purslanes are also probably drought
tolerant due to their thick fleshy leaves, although I don't know this for
certain. When I lived in Florida, on the beach there lived a variety of
purslane that must have been both drought and salt tolerant, since it thrived
in the sand and salt air. I have purslane growing wild in my backyard - we
tried cooking it once, but no one would touch it, too slimy. Maybe we'll try
it raw in salad next time.
Also in Florida, we had black, white, and red mangroves, which live in salt
water and make very attractive trees. Might be useful for landscaping around
a salt water pond.

help on chloride extraction from plant tissue (ajlewis@ucdavis.edu (Amanda))

Subject: help on chloride extraction from plant tissue
What protocols are labs using for chloride extraction? I have discovered
that the method I was given to extract chloride is in error and am curious
if other labs are using this particular method.
Specifically, I am interested to know
1) if labs wash tissue samples before drying and grinding?
2) if chloride can be extracted without agitation and/or filtering?
3) if chloride can be extracted with DI only?
thanks for your time,

Usually we wash sample in distilled water 'only' if they are nonabsorbing
i.e. roots are rinsed in dilute sorbitol because distilled water can leach
components out. Leaves are OK in distilled water for brief periods.
AFter drying and grinding, samples for Cl analysis are extracted in dilute
nitric acid. Gentle shaking overnight on an oscillatory or rotary shaker will
do. Actually, we 'store' samples for several days this way and gently shake
prior to sampling. You can also let the suspension settle and pipette
aliquots off the top. Analysis is usually done by coulemetric titration with si
silver. Cotlove for a reference, but I forget the year.
Jim Osters suggestion to contact Don Layfield is a good one.

greetings to all (David.Chen@uts.edu.au (- - - -))

Subject: greetings to all
Hi all I'm David Chen (Bsc.Hns, and PhD student at the University of
Technology, Sydney).
I'm from Sydney, Australia.
I am interested in salinity because as you are well aware salinity is one
of the most serious environmental problems in the world today. I am just
interested in how salt tolerant plants can be used to alleviate this huge
problem.
My experience in this area includes completing BSc project on the
Physiological Mechanisms of salt adaptation I Eucalyptus microcorys, also a
BSc (Hons) on the genetics of salt adaptation in a salt sensitive and salt
tolerant strain of Eucalyptus microcorys, in tissue culture. I have been
down to the Murray DARLING area last year and have spoken and witnessed the
results of salinity on the land.
The questions that I would like to be discussed include: Any news or
updates on the mechanisms of salt tolerance in non halophytes, any genes
that have been found on salt tolerance, how the people on the land are
trying to alleviate the problem, and any areas i guess involving salt
toerance and salinity.
My knowledge of salinity has grown over the past 3-4 years, and hopefully
is still growing. I guess to explain everything that is involved in
salinity and sodification would take too long to explain here, but if you
want more info, well you can write to me in person ok.
thank you for your time,

Dear Friends:
I am a Researcher at the Kuwait Institute for Scientific Research. I am
looking for addresses (and the name of the Contact Person, if possible) of
organizations that support research in biosaline agriculture. Could anyone
help me in this matter?
Thanks for your help.
