為篩選出適合江漢平原生長的狗牙根品種,觀察了14個狗牙根品種葉片上、下表皮微形態(tài),并測定了其長、短細(xì)胞和氣孔的數(shù)量及長寬。結(jié)果顯示,不同品種狗牙根的葉表皮的微形態(tài)結(jié)構(gòu)類似,表皮細(xì)胞垂周壁呈波浪狀,上、下表皮均有氣孔分布,但各項指標(biāo)差異顯著;雄鷹、太陽城和野生狗牙根多項指標(biāo)均較大,對田園土生境和江漢平原多雨的環(huán)境都具有很好的適應(yīng)性;新農(nóng)1號、普通脫殼狗牙根和普通未脫殼狗牙根的各項指標(biāo)均居末位,對田園土生境適應(yīng)性差;普通脫殼狗牙根也不適應(yīng)植物砼生境,而野生狗牙根具有良好的田園土和植物砼生境適應(yīng)性;喀什的葉片上、下表皮長、短細(xì)胞排列緊密,Pyramid和普通脫殼狗牙根氣孔密度較大,均能很好的適應(yīng)干旱環(huán)境。
