Researchers at Ben Gurion University are working to
domesticate wild trees bearing fruits and nuts in the hope of
saving people from starvation

W

hat fruit is juicy,
high in vitamin C,
and is eaten by
squeezing out the juice? If
you said, "orange," you're
wrong. Is is the morula and
you can't buy it in any fruit
store.
What roasted nut tastes
like a cross between a cashew
and a pistachio? You don't
know? Not surprising. Very
few people have tasted the
yehib.
Dr. Yosef Mizrahi and his
team of researchers at Ben-
Gurion University of the Ne-
gev have eaten both — in the
interest of science.
Dr. Mizrahi and his asso-
ciates at the University's In-
stitute for Applied Research
are speeding up a process
which normally takes genera-
tions, and without their help,
might never take place at all.
They are working to domes-
ticate wild trees of arid
regions which bear edible
fruits and nuts of high nutri-
tional value. The yehib is

well-balanced in nutrients in-
cluding protein and being
drought resistant, could con-
ceivably save people from
starvation if it could be
grown in sufficient quantities.
"This is a long, slow pro-
cess. We are still in the early
stages of trying to learn what
the variables are in the
growth and development of
these plants," says Dr.
Mizrahi. "In the case of the
yehib, we have been trying to
cultivate the plant under a
variety of different conditions
of climate, soil and water, to
learn exactly what is needed
for it to thrive."
So far, six experimental
plots have been established,
with plants that were started
from seed in specially quar-
antined greenhouses. The
seeds were brought to BGU
from Africa where the plant
grows wild, but in very
limited and diminishing
quantities. "This plant has
been declared an endangered
species by the UN En-

vironmental Program."
The natural diversity. of
Israel's Negev desert provides
an ideal laboratory for this
kind of experimentation. The
six plots cover a broad spec-
trum of conditions similar to
those of the arid and semi-
arid African regions which
exist in many regions
throughout the world.
"We know the yehib is
drought-tolerant. We are try-
ing to learn if it is also salt-
tolerant," Dr. Mizrahi says.
Other variables being ex-
amined are soil conditions
and temperature.
Dr. Mizrahi says there are
two purposes for the kind of
research he is conducting at
the University's Institute for
Applied Research. There is
the possibility of the develop-
ment of a new crop for Israel
and equally important, it
allows the use of the Negev as
a laboratory for the develop-
ment of desert crops world-
wide. "The yehib, for instance,
grows in the wild only in a
