basis of the number of viable kernels of seed per pound rather than on
the basis of a given number of pounds of seed per acre. This station
has also recently determined the correct spacing of peas grown for
processing. About 20 seeds to the yard of row was found to give
the largest net returns per acre of peas grown.
ORNAMENTAL PLANT RESEARCH
Recent ornamental plant research at the State experiment stations
has been directed mostly toward floriculture, particularly with those
flowering crops that are grown under glass. At the New Jersey station
flower production as well as quality was affected when roses
growing in greenhouse benches in sand were supplied with boron additives
in the nutrient solution. Under normal conditions a value of
0.25 p. p. m. of available boron in the substrate was found to be the
most effective concentration for a favorable response. The Mississippi
station in research on the propagation of camellias has shown
that potted plants are superior to bare-rooted understock in the
grafting of small camellias.
Success with the exportation of anthuriums into the United States
has led the Hawaii station to study the potentialities of this crop.
A study of flower yield has indicated that there is an inherent variability
of from 4.1 to 7 in different plants. Plants with highyielding
quality flowers are now being used in a breeding program.
At the Alabama station fertilizer studies with gladiolus are in progress.
Fertilizer applied early in the growth of the new plant delayed
production, indicating that feeding should be delayed until growth of
the corms is under way.
Greenhouse rose culture has long been studied at the Ohio station.
Recent reports show that negative results were obtained in an attempt
to influence blind wood production by varying the nutritional level
of the medium in which the rose plants are growing. The minimum
level of nutrition that will give the most profitable production in
commercial plantings is recommended.
At the California station a study of the spacing of rose plants to
obtain the most profitable number of cut flowers gave interesting
results in the first year of a 3-year test. Roses spaced 17,000 plants
per acre produced for the first year only one-half the value of those
spaced 51,500 plants per acre. The returns from the two methods
of planting were $42,000 and $70,000, respectively, and the cost of
the additional plants for the closer spacing $1,200.
Improved cultural methods for growing greenhouse hydrangeas
have been developed at the Maryland station. Applications of nitrogen
-fertilizer during the forcing season resulted in an increase of
pink flowers. Under phosphorus fertilization plants produced pinker
flowers but only when nitrogen had also been applied. Potassium
fertilization resulted in a bluer flower color.
The New York (Cornell) station has established conditions under
which a number of cut flowers will keep most satisfactorily in storage.
Carnations, pompomn chrysanthemum, roses, lily-of-the-valley,
and garden lilies stored most successfully, and injury from mold was
least, at temperatures of 31 F. Flowers stored in a dry condition
and wrapped in moisture-proof packages were generally superior
to those stored at the same temperatures with their stems in water.
