THE CHINESE .JUJUBE. 11 
Mention should be made of the seedless varieties. Meyer's notes 
refer to 8. P. I. No. 35253 as being seedless, but the f ru its produced 
in this country by this number have had seeds. The Mu Shing Hong 
variety (S. P. I. No. 22684) produces a small percentage of seedless 
fruits on the trees growing in the Plant Introduction Garden at 
Chico. Calif., in addition to the large number of fruits bearing 
normal seeds. 
PROPAGATION. 
The jujube may be propagated by means of seeds. 3 cuttings, buds, 
and grafts. 
SEEDS. 
Plants secured from seeds bear small fruits, most of which are little 
more than skin and seed, and are of value chiefly as stocks upon 
which to graft the large-fruited varieties. The seeds of the large- 
fruited varieties show a low percentage of germination, whereas those 
of the small-fruited seedlings show a germination varying from 25 
to 95 per cent. 
As soon as the fruit is ripe it should be gathered, placed in a water- 
tight container, and covered with water; or it should be buried in 
wet soil. After a week or 10 days the pulp will have fermented and 
decayed sufficiently to make it possible to remove it without difficulty. 
The pulp can be removed by using a square-bottomed trough, 
the bottom of which should be lined for a distance of about 3 feet 
at one end with a piece of wire screen having about four meshes 
to the inch. A board slightly narrower than the trough and about 
18 inches in length should be covered on one side with wire screen 
of the same mesh as is used in the trough. A handle should be fitted 
to the other side, to make the board convenient for this work. The 
fruit should be placed in the trough and the pulp removed by moving 
the piece with the handle back and forth over the top with sufficient 
pressure to break away the pulp. A stream of water should be 
allowed to run through the trough during this process, large enough 
to remove the pulp as it is freed from the pit. Removable cross- 
bars about 2 inches in height should be placed at intervals of 1 foot. 
The pulp and light empty pits will be carried over, while the pits 
with viable seeds, being heavier, will lodge between the crosspieces. 
After the pulp has been removed, the surplus moisture should be 
drained from the seeds. They should then be stored and protected 
from heat and drying, or they can be stratified in sand and kept in 
a cool, moist place. Three or four weeks before they are to be put in 
the ground they should be stratified in moist sand in a warm place ; 
if previously stratified they should be moved to a warm place. Where 
greenhouse space is available and the seeds are to be stratified in 
large quantities, a layer of sand about 2 inches deep may be spread on 
a bench having bottom heat. A piece of burlap should then be spread 
over the sand: this, in turn, should be covered with a very thin layer 
of sand, on which the seeds are spread in a thin layer, and barely 
covered with sand. Over this another piece of burlap is spread and 
covered with about an inch of sand. The sand should be kept moist, 
but not wet, Where this method is used, it is possible to stratify a 
5 The word 'seed" is used for convenience. Technically, this is a 2-celled putamen, 
baring one or two seeds.
