图3. 芦苇新变型的鉴定
(A) 自然生境中的金条芦苇; (B) 金条芦苇的小穗(bars=5 mm); (C) 金条芦苇细胞核的流式细胞分析结果; (D) 金条芦苇和变叶芦竹叶绿体基因片段(从trnG-UCC到trnT-GGU)大小的差异, 变叶芦竹(Ad)产生607 bp的条带; 芦苇产生1069 bp的条带(Pa为小清河芦苇克隆C6, DR和SR是河西走廊生长的沙丘芦苇和沼泽芦苇, G1-G3均为金条芦苇)(M: 分子标记); (E) 金条芦苇模式标本

Figure 3. Identification of a new form of Phragmites australis
(A) Phragmites australis f. Goldstripe in natural habitats; (B) Spikelets of goldstripe reed (bars=5 mm); (C) Identification of ploidy level by the flow cytometric analysis on the goldstripe reed nuclei; (D) The size difference of a DNA fragment (from trnG-UCC to trnT-GGU) as revealed by PCR between goldstripe reed and Arundo donax var. versicolor, A. donax (Ad) produced a 607 bp band; common reeds and goldstripe reed produced 1069 bp bands (Pa indicates Xiaoqinghe reed C6, DR and SR indicate desert dune reeds and swamp reeds growing in the Hexi Corridor, and G1-G3 are all goldstripe reeds)(M: Molecular marker); (E) A type specimen of goldstripe reed
