摘  要

張元聰、王裕權、陳燿煌•2008•苗齡及摘心對雞冠花生育影響之研究。台南區農業改良場研究彙報51:38 - 45。

  以288格穴盤育苗3週及4週與直播栽培比較結果包括株高、莖粗及葉數,直播處理均優於288格穴盤處理,穴盤處理中三週苗齡又優於四週苗齡,顯示雞冠花育苗時間不宜超過3週,以避免植株老化對生育有不良影響。摘心及種植密度處理以不摘心的處理下高密度栽培之株高及切花長度較長,但在摘心處理下,低密度的切花較長、側花較大,高密度下摘心處理會使生長空間不足導致切花品質下降。

關 鍵 詞:雞冠花、苗齡、摘心

Effects of Seedling Aged and Pinch Treatment on the Growth Characters of Celosia.1

Chang Y. T., Y. C. Wang and Y. H. Chen

Summary

  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.
