The primary haustorium can be induced by some chemicals.

2有些化学物质可以诱导初生吸器的产生。

C. deserticola is an active parasitic plant, and secondary haustorium originated after adhesion between the primary haustorium and young roots of the host.

3肉苁蓉属于主动寄生植物，其在初生吸器与寄主幼根黏连后产生次生吸器。

The inheritance of haustorium of yellow rust in the durable resistance cultivars was recessive, the degree of dominance was -0.47~-1.83. There were 1~2 genes which controlled the number of haustorium.

小麦持久抗性品种中条锈菌吸器的遗传为部分隐性，显性度为-0.47~-1.83；控制条锈菌吸器数目的基因大约有1~2个。

The results showed that the number of haustorium of P. striiformis in AQ and LB was 44.2/mm2 and 23.74/mm2 respectively. But there was no difference with the number of hastorium of the pathogen between XN (89.83/mm2) and MX (102.02/mm2), which indicated that XN had no resistance to haustorium.

结果表明：AQ和LB中条锈菌的吸器数目分别为44.2/mm2和23.74/mm2，两个品种对吸器均表现较强的抗性；XN中条锈菌吸器数目(89.83/mm2)与MX(102.02/mm2)无差异，未表现出明显的抗性。

DMBQ, resorcin, ferulic acid, and hydroxybenzoic acid were effective chemical signal substances in the inducement of haustorium, but the haustorium formation rate was only 3.3%.

适当浓度的2，6-二甲氧基对苯醌、间苯二酚、阿魏酸和对羟基苯甲酸均可诱导肉苁蓉种子萌发形成吸器，吸器形成率最高为3.3%。

Co-culture with Haloxylon ammodendron, the primary haustorium conglutinate with young roots of the host (0.1 mm), pass through the host's epidermis and cortex, then connect with the vascular bundle and transform into secondary haustorium, shaped by fundamental tissues of differentiation and development.

肉苁蓉与寄主梭梭共培养，其初生吸器主动与寄主幼根（0.1mm左右）黏连，穿过寄主根表皮和皮层后与维管束连通形成次生吸器，肉苁蓉植物体分化、发育的基本组织形成。

DMBQ, ferulic acid and resorcin were effective chemical signal substances in the process of seed germination and haustorium formation of Cistanche deserticola. 4.The embryo is consist of 12 cells, the endosperm cell degraded so as to provide nutrition for the embryo development .As a result, germ tube differentiated from the embryo and came out through micropylar end, the small cell at the tip of the germ tube held the capacity of cleavage and the other cells grew big ,so the germ tube elongated .The anterior extremity of germ tube swelled to form haustorium under chemical substances treatment, the haustorium cell stained ,especially its portrait because of the lignification of the cells.

肉苁蓉种子的胚是由12个细胞紧密排列形成的圆球状胚，球形原胚分裂增殖的同时，胚乳细胞分解，为胚细胞的增殖提供营养，最终胚上分化出的芽管由珠孔端冒出，芽管前端细胞较小，具有旺盛的分裂能力，后部细胞体积增大，芽管逐渐伸长，在化学物质的诱导下，芽管由中部至前端细胞膨大分化出初生吸器，初生吸器呈帽子状，而这些细胞比其周围的细胞着色深，吸器纵向局部区域的番红染色加深，细胞高度木质化。

When they were added respectively. DMBQ+ ferulic acid and DMBQ+ resorcin had synergistic effect, the haustorium formation rate doubled in this treatment. DMBQ +ferulic acid + resorcin together with 6-BA+ GA3+ IBA showed the most effective inducing function, and the haustorium formation rate was 13.3%. The results above showed that there were different chemical signal substances functioned in the process of germ tube germination and haustorium formation of Cistanche deserticola respectively.

DMBQ与阿魏酸和DMBQ与间苯二酚组合均表现出协同作用，使肉苁蓉种子形成吸器率增加1倍；DMBQ +阿魏酸+间苯二酚与激素6-BA + GA3 + IBA共同组合吸器形成率提高到13.3%，说明寄生植物肉苁蓉种子萌发过程芽管和吸器形成分别由不同的化学信号物质调控，DMBQ、阿魏酸和间苯二酚在诱导肉苁蓉种子萌发过程形成吸器具有决定性作用。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
