中文摘要 | 本試驗的目的在藉生長分析以瞭解半蔓性菜豆在春作、秋作各生育時期 植株各部位生長特性的變化及其間之相互關係,以做為生理、栽培之參考。其結 果如下: (一) 春作時氣溫由低而高(15℃~28℃),秋作時氣溫由高而低(25℃~15℃),因而造 成春作與秋作的生長差異:A-156品種在秋作的生育日數為77天,CITC-70-29 品種為84天,而在春作時兩品種均為70天:A-156之株高在春作及秋作均於始 花後二星期不再長高。CITC-70-29在春作於始花後二星期,在秋作於始花後 三星期不再長高;兩品種之節數,分枝數,在春作及秋作均於始花後一星期達 到最多,以後不再增多:A-156之莢數在春作及秋作均於始花後二星期達最 高,以後漸減,CITC-70-29之莢數在春作於始花後二星期,在秋作於始花後 三星期達最高,以後漸減:A-156之葉面積在春作及秋作均於始花後三星期達 最高,以後漸減,CITC-70-29在春作於始花後三星期,在秋作於始花後四星 期達最高,以後漸減。 (二) 半蔓性菜豆之平均生長速率(CGR)隨著生育日數增加而增加,在始花後二星 期達最高,以後急速下降。平均相對生長速率(RGR)隨著生育日數增加而漸 減,在遞減過程中,在開花期前後有二個升峰。平均淨同化率(NAR)在生育 初期較高,以後降低再升高,後再降低,在開花期前後也有二個升峰。 (三) 半蔓性菜豆之葉面積指數(LAI)曲線與葉面積曲線一致,由低而高,至始花 後三星期達最高,以後漸減。葉面積比(LAR)在生育初期會升高,以後隨著 生育日數迅速減低。 (四) 半蔓性菜豆之地上部乾物重,在營養生長期主要由葉及莖所構成。葉在始花 後一星期前,其乾物重比(DWR)均在50以上,以後豆莢急速增加及增重,葉 之DWR才急速減少。莖DWR也隨著生育日數增加而增,在始花後一星期達最 高,以後漸減。豆莢之DWR在始花後開始急速增加,至成熟時其DwR可達60。 半蔓性菜豆之營養器官乾物之累積,在種子萌芽後三星期開始急速增加,而 生殖生長則在始花後一星期才開始明顯的增加。 |
英文摘要 | Plant height of semipole bean varieties. A-156 and CITC-70-29 extend to thelongest height at two to three weeks after the begining of blooming The number ofnode and branch at one week, leaf area at three to four weeks,number of pod attwo to three weeks after the begining of blooming reached their hingest point respectively. CGR of semipole bean increased along with growth, and reached to a highestpoint at two weeks after the begining of blooming. RGR decreased along withgrowth and two raising peaks were observed before and after blooming period. Thesame phenomenons Were observed in NAR measurements, LAI increased from lowto high and reached to the highest point at three weeks after the begining ofblooming. LAR raised at the begining of growth then dropped sharply. DWR ofleaf and stem reached to the highest point and larger than 50 at one week afterthe begining of blooming. While DWR of pod increased rapidly after the beginingof blooming, then reached to 60 at maturithy. Cumulative dry material of thevegetative organs started to increase rapidly at three weeks after emergency. Reproductive growth increased obviously after one week of the begining of blooming. |
