Abstract
種子和苗木生產為農業之母，有健康的種子苗才能生產好的花卉產品。而好
的健康的種子苗生產包括種子、介質、環境及栽培管理等重要因子。種子生產有
幾個必備條件，即最大遺傳純度，最大種子活力，和已去除帶有特定病原的種子，
這也是健康種子苗生產的必備條件。種子採收後要盡快進行烘乾、篩選、保存的
動作，以延長種子壽命。育苗播種時，播種前可用生長調節劑如激勃素打破種子
休眠與進行種子滲調處理，在提高種子的發芽率與整齊度；機械化省時省工的穴
盤育苗系統已漸漸取代傳統的育苗方式；而合適的水分、溫度、氧氣和光線等都
是種子的發芽與幼苗的發育所要注意的重點，以及介質的選擇與調製也非常重
要。利用特殊的微生物分泌物如木黴菌(Trichoderma spp.) 或膠狀青黴菌
(Giocladium spp.)或化學物質如水楊酸鹽、亞磷酸鉀能刺激植物啟動防禦系統，
可誘導植物產生植物防禦素對抗入侵的病原菌及增強植物防病的功能。從生產、
採收、考種、貯藏、育苗，每一步驟流程都影響到種子和種子苗的健康與品質，
本文將針對這些影響因素加以說明。
Seeds and seedlings are the basic in agricultural production. Good flower’s
product must be come from healthy seedling. Seed quality, medium, environmental
condition and field management are major influence factor for healthy seedling. Good
seed quality will also be included maximum genetic purity, maximum seed viability
and specific pathogen free. When seeds harvests must be dried, screened and stored in
short time for postponing seed life. Breaking dormancy (e.g. growth regulator of
gibberellin) and priming treatment before sowing will be increased the rate of seed
germination and uniformity. Plug tray system by means of mechanization and
save-labor culture, save-time culture is gradually taking over the traditional seedling
growing pattern. The optimum condition of water, temperature, oxygen and light…
etc., will be beneficial for seed germination and seedling growth. Medium kinds
should be considered is also very important factor. Using specific secretion of
microorganism, e.g. Trichoderma spp., Giocladium spp. or chemical compound, e.g.
salic acid, phosphorous acid could induce plant defence system, by means of
phytoalexin production to resist pathogens invasion and to enhance plant defence
function. This article was investigated about influence factors(such as seed production,
harvest, drying, storage and nursery culture…etc.) of seed quality and seedling health.
