The correctness is over 99 %. ( 5 ) shape features studied were aspect, first invariant central moment, elongatedness, roundness, circularity and thickness. aspect and first invariant central moment are the most effective shape features for identifying monocotyledonous weed from dicotyledonous weed, and the correctness was 93 %
（ 4 ）利用修正的色度公式，由判別分析法確定色度閾值，對雜草圖像進行閾值分割，能夠有效地識別植物與非植物背景，正確識別率在99以上，但色度的計算量大於過綠特徵的計算量，不利於雜草識別速度的提高。 -
Juncaceae ( rushes ) a family of monocotyledonous plants, mostly herbs, with long, narrow grasslike or cylindrical leaves spirally arranged, but usually arising close to the ground
燈芯草科（燈芯草屬） ） ：單子葉植物的一個科，多為草本，狹長扁平或柱狀的葉呈螺旋狀排列，通常簇生。 -
In a monocotyledonous plant, the same role is played by the scutellum, as in a cereal grain.
在一個單子葉植物中，同樣的作用由盾片來承擔，如在一個穀粒中。 -
Thickness is an effective feature for identifying corn from monocotyledonous weed, and the correctness was 90 %. ( 6 ) six shape features were used to design back - propagation network for weed identification and the network structure was 6 - 12 - 3
（ 6 ）設計了用於雜草形狀識別的bp網路，結構為6 - 12 - 3 ，並對學習誤差、隱層結點數對網路性能的影響進行了研究。 -
In this study, we constructed two plant expression vector with rip gene from barley and linked to two promoters which have high promoting efficiency in monocotyledonous plants, respectively, and then transferred to rice mediated by agrobacterium tumefaciens. the main factors of affecting transformation were investigated and established its regeneration and transformation systems. pcr analysis showed primarily that rip gene had already integrated into rice
本研究構建了分別由單子葉植物中啟動效率較高的pact和p2 35s啟動子調控的大麥核糖體失活蛋白基因（ rip ）的植物表達載體，通過農桿菌介導法轉化水稻，經pcr檢測初步驗證了rip基因已導入水稻。
