摘要

以4個仙草品種，分3月16日及4月16日二期移植，探討不同移植期對該等品種之農藝性狀，產量及主要化學成份含量之影響，結果顯示在二移植期公頃平均乾草量，小葉匍匐種(A)爲4,529kg，小葉直立種(B)爲5,043kg，大葉直立種(C)爲4,735kg及大葉匍匐種(D)爲6,915kg。但就移植期別加以探討，發現A、C和D三品種第一移植期較第二移植期高產，尤以D品種在第一期移植公頃乾草量6,932kg爲最高。另就仙草主要化學成份分析結果，發現品種間之可溶性無氮物(NFE)含量差異不大。至於影響仙草凍凝膠強度，可能因品種間之葉量百分率高低有關之假說，經就化學成份分析顯示並未被證實。

並列摘要

Four varieties (A-small leaf runner type; B-small leaf bunch type; C-big leaf bunch type; D-big leaf runner type) of hsian-tsao (Mesona procumbens Hemsl) were transplanted on March 16 (S1) and April 16 (S2) 1984 to evaluate the effect of variety and transplanting date on the agronomic characters, dry grass weight and gross composition. Based on the average of 2 transplanting dates, variety A, B, C and D produced 4529, 5043, 4735 and 6915 kg/ha dry grass, respectively. More yield was observed in transplanting date S1 than S2 in varieties A, C, and D. The highest yield was observed in variety D transplanted on S1 which produced 6932 kg/ha of dry grass. There were not many differences in nitrogen free extract among 4 varieties. We failed to confirm the hypothesis that Gelforming strength is positively-correlated to the leaf percentage of the plants by the analysis of gross composition.
