STORAGE OF FRUITS, VEGETABLES, AND FLORISTS' STOCKS 47 



However, these as well as tulips (Tulipa sp.) are usually not stored 

 because better results are obtained by planting them as soon as they 

 are received. Paperwhite narcissus (93) may be stored at 75° to 80° 

 for 5 to 7 months from digging time. 



Tulips are usually not stored in any packing material, although 

 the use of such material may be advantageous for long storage. Tem- 

 peratures of 36° to 38° F., except for short storage, are considered 

 rather low for tulips shipped from the West in which the buds are 

 already formed. The best storage temperature for shipped tulips is 

 between 50° and 55°, at which temperature range they may be kept 

 for 4 to 6 months. Tuberoses (Polianthes tuberosa L.) stored at a 

 temperature of 40° to 45° may be expected to keep satisfactorily for 

 6 to 8 months. 



Bulbs of the genus Lilium, of which there are approximately 50 

 species, are like most other bulbs in giving best results if planted when 

 received. However, as Easter lilies are forced during the entire year, 

 it becomes necessary to provide cold-storage conditions suitable for 

 satisfactory holding until they are wanted for planting. The bulbs 

 should be packed in boxes in thoroughly dry soil if rooting and desic- 

 cation are to be prevented. A temperature of 35° F., with a relative 

 humidity of 75 to 80 percent is recommended ; under these conditions 

 they may be held for 6 to 8 months. 



The procedure of storing certain bulbs for a time previous to plant- 

 ing at a temperature that will subsequently hasten flowering is in con- 

 siderable use commercially. Bulbs so handled are said to be "pre- 

 cooled" (7,27,28).
