| Popis: | The study revealed that China aster seeds lose viability quickly if stored under ambient conditions. At the end of 12th months, seeds stored at refrigerated condition (5-70C) still maintained high seed germination (64.00%) at field condition well above the minimum seed certification standards. However, in case of ambient storage very drastic reduction in seed germination was observed. It was 32.43 % for first months and reduced to 14.95 % for second month by declining 53.90% as compared to first month and thereafter no germination was recorded at field condition. Results from the interaction effect indicated that previously stored seeds of China aster for six months in aluminium foil and kept under refrigerated condition recorded higher seed quality parameters viz. percent seed germination at field (92.67 and 72.00%), percent survival of seedlings (89.33 and 70.67%), height of seedling (11.53 and 8.60 cm), shoot length (7.00 and 5.10 cm), root length (4.53 and 3.50 cm), shoot weight (0.42 and 0.33 g), root weight (0.040 and 0.027 g), root:shoot ratio (0.095 and 0.082) and percent seed germination at laboratory (97.33 and 76.00%) for first and sixth month, respectively. |
