Effects of Seedling Aged and Pinch Treatment on the Growth Characters of Celosia.1
Chang Y. T., Y. C. Wang and Y. H. Chen
To compare among seedlings of celosia was raised in a 288 plugs for 3 or 4 weeks and directed sowing in field. The directed was better than plug seedling in plant height, stem diameter and leave number. The plug seedling for 3 weeks was better than 4 weeks. Those results ensure the seedling wasn’t raised in plug over 3 weeks to avoid plants ageing and effect the growth. To treated celosia seedling with or without pinch and plant density. The plant height and cut flower length was longer in non-pinch with high density. Pinching with low density had longer cut flower and larger branch flowers. But pinch with high density had low quality of cut flowers because small grow space.
Key words: celosia、seedling age、pinch treatment.
