They were divided into three groups of four of each type of bulb, covered with layers of news-

paper (for insulation purposes), then placed in an area in which the temperature ranged from

-4°C to 5°C. This procedure was designed to force the bulbs.

Periodically they were checked and watered with their respective pH rain as needed.

(See Table 1, Early Distribution of Water by Frequency and Volume.) The amount of water was

measured carefully using measuring spoons or cups to ensure accuracy.

On January 7, after 57 days of simulated winter, all bulbs were brought into an area that

had a temperature range from 13°C to 18°C. The layers of paper were not removed, thus slow-

ing the beginning of bulb growth. This procedure was followed in order to make the transition

from winter to spring conditions less drastic, a transition which otherwise may have had a limit-

ing effect on the growth of the bulbs.

After four days in this environment, the bulbs were placed in a warmer area (18°C to

21°C), placed under artificial sunlight, and the paper removed.

Then, the bulbs were observed every day for growth and soil dryness. If needed, the bulbs

were watered with a predetermined amount per bulb. (See Appendix A, Water Distribution
