The digested water samples of all three irrigation sources, soil and spinach plant parts were filtered through Whatman No.
Similar trend was recorded in spinach plant parts during 2012-13 (Fig.
Among spinach plant parts, leaves contained greater heavy metals (Pb, Ni, Cu, Cd, Fe and Cr) contents than roots irrespective of irrigation water source during both the years of study.
This should produce a spinach plant
about 3 1/2 to 4 inches in diameter, the best size for overwintering.
Caption: ARS geneticist Beiquan Mou and colleagues analyzed hundreds of spinach plants
to find ones with less oxalate, a compound linked to kidney stones.
Interaction of Escherichia coil with growing salad spinach plants
They found that the concentration of soluble sugars, and the percentage of newly fixed C that went into starch, were greater in S deficient spinach plants
than in controls.
coli cells had been able to migrate into the roots of spinach plants.
The researchers also examined baby spinach plants over the course of 28 days after germination to see whether any of the E.
coli had become "internalized" in leaves or shoots of baby spinach plants grown in soil.
To help protect tomorrow's spinach against leafminers, researcher Mou has developed two kinds of parent spinach plants with impressive natural resistance to the insect.
The parent spinach plants result from 3 years of rigorous field tests by Mou and colleagues.
Today's spinach plants
, for example, hoard calcium in crystal forms that nourish the plant but are not as biologically available to humans.
Excess salts result in stunted spinach plants
with small dark green leaves.
All the water spinach plants
that have been found in Florida's waterways are likely escapees from home gardens or illicit growing plots, according to Kipker.
