| Summary: | Seeds of <em>B. purpurea</em> L. of red flowers and <em>B. alba </em>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 KNO<sub>3</sub> or 50 and 100 mg/L GA<sub>3 </sub>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 <em>B. alba </em>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 KNO<sub>3</sub> or 100 mg/L. Also highest germination percentage 100 % were achieved from planting <em>B. alba</em> at fourth date and treated with 200 mg/L KNO<sub>3</sub>. Culture seeds of <em>B. purpurea</em> 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 <em>B. alba </em>and <em>B. purpurea </em>at first date for different treatments compared with other dates. Highest length of seedlings and leaves number were achieved from planting <em>B. alba </em>and <em>B. purpurea </em>at first date of different treatment compared with other dates. |
