不同來源蘆筍品種其幼苗在臺灣北部生長之研究

A Study on the Growth of Asparagus (Asparagus officinalis L.) Seedling of Varieties from Different Sources in the Northern Taiwan

本試驗經檢察蘆筍不同之品種，不同產地之種子，及不同播種期之幼苗生長情況，可知蘆筍種子在適當溫度25-30℃下發芽較快而整齊，其幼苗初期生長亦以25℃左右為付佳，自幼苗之莖與貯藏根增長上觀之，各品種之趨向相似，但美麗華盛頓省產一代者，則能在冬季低溫來臨前減慢生長，至於莖數有貯藏根數，美麗華盛頓500者較多，而貯藏根直徑卻較美麗華盛頓省產一代者為細，致形成兩品種之植株總鮮重差異不顯著，在根冠之增大上，U.C.309及美麗華盛頓500者之長寬差均較大，複鱗芽數亦較多。由前述現象可證明在幼苗生長上，不同品種及不同產地種子之間有所差異。依照農林應現行蘆筍定植苗標準，則上述三品種雖在不同時期播種（U.C.309在五月，其他兩品種在六月），其幼苗均能在移植後三個月內到達標準。

A study on the growth of asparagus seedlings of different varieties, different seed sources and with various seeding times has shown some interesting results, such as: early and uniform germination under optimum temperature (25-30℃) condition; good primary growth under cooler temperature (25℃); no varietal differences in height of stalks and length of storage roots; varietal differences; in dormancy; varietal differences in number of stalks and storage roots and diameter of storage roots; no significant difference in total fresh weight between varieties (Mary Washington 500 and Mary Washington (Taiwan); difference in width length. ratio and number of compound buds of crown exists between varieties (Mary Washington (Taiwan) with smaller ratio and less buds). In accordance to the Taiwan Provincial Standard of Asparagus Seedlings for Setting, the seedlings from UC 309 seeded in May and Mary Washington 500 and Mary Washington (Taiwan) seeded in June, all met the standard within 3 months.
