摘要

試驗採用「台中亞蔬四號」及「農友301」二個番茄品種，定植前苗株經20/12℃低溫處理10及5天後，第一花序著生節位、著果率與各花序節位著生高度、著生花數、著果數及不同收穫期間的果數等性狀以「台中亞蔬四號」較高或較多，平均單果重以「農友301」較重；二品種間第一、二花序的始花期、始收期、早期產量及第二至五花序著生節位差異不顯著。第一花序的花數與著果數，隨四、五、六週苗齡的增加而降低，各花序著生節位與高度則隨苗齡增加而增高；但不同苗齡對著果率及第二花序以後之花數與著果數、不同收穫期間的產量及單果重並無影響。苗株經低溫處理後，顯著延遲始花期及始收期，對平均單果重無影響，而早期收種果數隨低溫處理天數的增加而降低；各花序著生節位除第一花序在低溫處理問差異未達顯著外，均顯著較對照之未經低溫處理者低。

Two tomato cultivars, Taichung Asian No.4 and Known-you 301, were tested in the this study. Seedlings of 4, 5, 6 weeks old were treated in 20/12℃ for 10, 5 or 0 days before transplanting. Taichung Asian No.4 was higher or larger in node of first inflorescence, fruit setting percentage, node height of each inflorescence, number of flower, fruit set number, and number of fruit harvest on different harvesting period. Know-you 301 was higher in mean weight of single fruit. There was neither significant difference in days to flowering of first and second inflorescence, and nor days to harvest, early yield, and node number of 2nd to 5th inflorescence. Flower numbers and fruit set number of first inflorescence decreased as seedling age increased from 4 to 6 week. Node number and position height for first inflorescence increased as age of seedling increased. However, no significant difference was found in fruit setting rate, flower number and fruit set number beyond 2nd inflorescence, yield of different harvesting period, and single fruit weight between these two cultivars. After seedling were treated with low temperature, days to flowering and days to harvest were significantly delayed with no affection on mean weight of single fruit. The harvested fruit number of early yield decreased as day of low temperature treatment increased. Aside of the first inflorescence, node number of each inflorescence treated with low temperature were significantly lower than the untreated control set.
