| Abstract | ||
| Seeds of B. purpurea L. of red flowers and B. alba ofwhite flowers cultured at fourth planting date, (1/8/2011), (1/10/2011), (1/12/2011), (1/3/2012) and treated with 100 and 200 mg/L KNO3 or 50 and 100 mg/L GA3 in addition to control treatment (socking in distilled water) to find best rate of germination and growth of the seedlings: the results indicated the highest germination percentage was 83.16 % from planting B. alba seeds. Highest germination percentage was 82.33 % obtained from culture seeds at fourth planting date. Highest germination percentage 66.45 % were achieved from control treatment and which was not significantly different with seeds treatment with 200 mg/L KNO3 or 100 mg/L. Also highest germination percentage 100 % were achieved from planting B. alba at fourth date and treated with 200 mg/L KNO3. Culture seeds of B. purpurea at fourth date and treated with 100 mg/L gave 100 % germination percentage. The lowest number of days for germination were obtained from planting seeds B. alba and B. purpurea at first date for different treatments compared with other dates. Highest length of seedlings and leaves number were achieved from planting B. alba and B. purpurea at first date of different treatment compared with other dates. | ||
