中文摘要 | 本試驗目的在探討不同年度間氣象因子之差異造成之夏季乾旱與非乾旱季節之芽葉農藝性狀對茶樹產量侑產量構成因子之影響,以了解乾旱期芽葉產量之重要影響因子,做為栽培管理及育種選拔的參考依據。本研究於1995至1997年在台東縣鹿野鄉龍田台地(北緯22°54’、東經121°07’、海拔175m),茶業改良場台東分場品種園之十年生茶樹品種進行調查研究。結果顯示,1996年之乾旱季節百芽重對萌芽密度為重要的負面影響因子,對萌芽密度的影響因子可能較易受環境影響而改變。影響百芽重之芽葉農藝性狀較為穩定,不易因環境差異而改變。在產量方面,由相關分析顯示,新品種群之產量與樹冠及萌芽密度關係較大;而地方品種群則與葉面積及百芽重呈顯著相關。由逐步迴歸分析也顯示,樹冠為相當重要的正面影響因子,在乾旱季節百芽重及萌芽密度也是很重要的影響因子;但地方品種群進入模式之因子較不一致,可能是未經人為選拔,性狀因子間之重要性不易區別。 |
英文摘要 | The experiment were conducted to study the effect of shoot agronomic characteristics of drought and no-drought period on thd shoot yield and yield component factors of tea tree (Camellia sinensis (L.) Kuntze) in the summer season from 1995 to 1997 at Lungteng of Luyeh district, in Taitung. The 100 shoot weight of drought season was very importantly negative effective factor on the shoot density, it was very easy to suffer environment effect. Effect of shoot characteristics factor on 100 shoot weight was steady, but also wasn't suffer environment effect. In correlation analysis, new variety group yield was higher positively significant correlated with tree canopy and shoot density. Local variety group yield was positively significant correlated with leaf area and 100 shoot weight . Stepwise regression analysis result indicated tree canopy was very important positively effective factor. The 100 shoot weight and shoot density of new variety group was also very important factor in drought season, but enter model factor was inconsistent in local variety group among years. Because possible hadn't by artificial selection leading to important factor wasn't easy appear difference. |
