中文摘要 | 本試驗採用豌豆嫩莢用品種臺中11號與臺中12號、甜脆型品種新珍與臺中13號,及豆仁用品種青仁為材料,於民國77年與78年秋在田間栽培,調查園藝及產量性狀,並分析生育期間之乾物質累積與分配特性,藉以瞭解不同類型豌豆栽培品種之產量生理表現。三個類型豌豆品種間的園藝性狀表現具有差異,株高以新珍最高,青仁最矮;節數增加速度以青仁最慢,其最終節數亦較少;單株莢果數與結莢節數均以臺中11號最多,而結莢速率則以新珍品種最低。臺中11號與臺中12號著莢節位對鮮莢產量的貢獻程度以第1-16著莢節最高,青仁之莢果則主要分佈於第1-8着莢節。77年試驗條件下新珍品種之莢果數最少,產量較低,唯鮮莢產量在四個品種間之差異未達5%顯著水準;78年試驗臺中11號之產量較77年試驗倍增,亦顯著較青仁品種為高,顯示環境因子的影響。豌豆於始花期以前僅累積植株10%以下之乾物量,且主要集中於葉片,其後以莖部之乾物質分配比率較高,至盛莢期後則以莢果為主要積儲器官。豌豆的單株乾物質累積量以臺中11號最高,為生育全期均具較高乾物累積速率之結果。臺中11號與12號及青仁品種之種子收穫指數為0.44-0.50,變異不大。新珍因營養生長繁茂,開花結莢時間較晚,植株之總乾物產量雖高,但以種子及莢果為基準之收穫指數僅分別為0.06與0.16。豌豆於始花至莢果開始快速充實期間,植株合成之乾物質有70%累積於莖葉,亦即營養器官與生殖器官間可能有競爭養分現象;於莢果快速充實期間增加之乾重則幾乎完全集中於莢果,可能有供源不足現象。 |
英文摘要 | Pea cultivars Taichung 11, 12, and 13, Sugar Snap and Dark Skinned Perfection, representing three different types of the crop, were grown in the fall crop of 1988. Horticultural characters and dry matter accumulation of the plants were investigated at intervals throughout the whole growth course, with special emphasis on the balance of source-sink relationship. Horticultural characters different among the tested cultivars. The rate of increase in node number, as well as total node number, were lowest for Dark Skinned Perfection. Numbers of pod and podbearing node per plant were highest for Taichung 11 and 12, while Sugar Snap was lower in pod number and yield due to its late-maturing nature under the experimental condition. Fresh pod yield was contributed mainly by the lower 16 pod-bearing nodes for Taichung 11 and 12, and by the lower 8 pod-bearing nodes for Dark Skinned Perfection. Fresh pod yield in 1988 ranged from 6,528 to 9,967 kg/ha with no significant difference among cultivars. The yield of Taichung 11 doubled in 1989, presumably the result of environmental influences. Less then 10% of total dry matter was accumulated by pea plants before initial flowering. Dry matter accumulation rate and total amount of dry matter produced were higher for Taichung 11 than for other cultivars. With the only exception of Sugar Snap, harvest indexes of seed (0.44-0.50) showed little variation among cultivars. Over 70% of dry matter produced during the period from initial flowering to the beginning of seed-filling was partitioned to leaves and stem, suggesting possible competition between vegetative and reproductive organs. The fact that dry matter production during rapid pod-filling was completely directed to pods indicated that source ability mightnot be high enough to meet the demand of seed development. |
