The results showed both ecotypes had adapted to their corresponding habitat and obviously had ecological plasticity.

Typical bands were used to analyze relation with ecotypes and characters of fruits, indicating that there was no relation between typical bands and ecotypes, but some extent relation between bands and characters of fruits existed. If all cultivars were divided into freestone and clingstone, melting and nonmelting, both freestone (ratio shared total survey, 41/56=73.2%) and clingstone (ratio shared total survey, 33/79=41.8%) appeared in the loci of S_(167)-1050 bp linked marker raised by Warburton et al. It was apparently not strong linkage between the marker and the character, and exchange rate of genes was high. If combinations of S_(167)-850bp and S_(167)-1050bp or S_(167)-850bp and S_(167)-1400bp were used to distinguish characters of fruits, 6 freestone accessions without clingstone ones and 6 melting accessions without nonmelting ones displayed in the first combination of markers, 20 clingstone accessions and 2 semi-freestone ones without freestone ones appeared in the second combination of markers.

通过典型带对不同生态型、果实性状为类别进行分析，结果未发现有与生态型相吻合的特征带出现，而将供试所有品种按离核、粘核和溶质、不溶质划分归类，供试品种在Warburton等得到S_(167)-1050 bp处粘离核分子标记，出现既有离核(占供试离核41／56=73.2％)，又有粘核(占供试粘核33／79=41.8％)，可见此连锁标记连锁性不强，发生交换的机率较高，而S_(167)-850bp带和S_(167)-1050bp带同时出现时，该组包含6个离核，无粘核品种；6个溶质，而无不溶质。S_(167)-850bp和S_(167)-1400bp同时出现时，包含20个粘核品种和2个半离核品种。

Resistance responses were studied in different Arabidopsis ecotypes after being inoculated by some important plant pathogens. According to the results, molecular mechanisms of resistance and expression of the defense-related genes in resistance and susceptible Arabidopsis ecotypes were studied. Results followed in this paper.All the 11 Arabidopsis ecotypes tested were incompatible to Erysiphe convolvuli, Alternaria brassicicola, Setosphaeria turcica and Verticillium dahliae.

本文在对拟南芥不同生态型接种不同植物病原菌后的抗病反应基础上对抗感表现不同的生态型的抗性机制及抗性相关基因的差异表达进行了研究，结果如下：测定拟南芥11个生态型接种8种不同植物病原菌后发现，供试拟南芥对田璇花白粉病菌、白菜黑斑病菌、玉米大斑病菌和棉花黄萎病菌均表现为非亲和反应。

Transgenic NahG and Col, Shakh-dara, Nd-1, WS-2 and Kas-1 ecotypes were all compatible to Sphaerotheca cucurbitae, Alternaria porri, Erysiphe cucurbitacearum and Alternaria solani. her ecotype was incompatible to Alternaria porri and Alternaria solani. C24, Est-1, Ws-0 and Bay-0 ecotypes were all incompatible to Sphaerotheca cucurbitae, Alternaria porri, Erysiphe cucurbitacearum and Alternaria solani.

转基因NahG和生态型Col、Shakh-dara以及生态型Nd-1、WS-2、Kas-1分别对丝瓜白粉病菌、葱链格孢、葫芦白粉病菌和番茄早疫病菌表现为亲和反应；生态型Ler对葱链格孢和番茄早疫病菌表现亲和反应：而生态型C24、Est-1、Ws-0和Bay-0对丝瓜白粉病菌、葱链格孢、葫芦白粉病菌和番茄早疫病菌均表现为非亲和反应。

The results showed that liquorices in five different habitats differentiated into at least two ecotypes, which was significantly correlated with their habitats, MG liquorice and JG liquorice grew in habitats with higher aridity falling into one type and their young seedlings had high drought-tolerating capability, but DG liquorice and SG liquorice and NG liquorice belonged to the other type and their seedlings had lower drought tolerance than the former seedlings; of all climatic factors in liquorice habitats, water was probably the dominating factor affecting the differentiation of liquorice ecotypes.

同时，对种植在相同生境下的2年生子代植株的地上部形态特征进行了观测。结果表明，5种生境的甘草至少已分化为2种生态型，且与它们的生境有显著的相关性，生长在生境干燥度较大的民勤甘草和酒泉甘草为一类，其幼苗的耐旱能力较强，而生长在干燥度相对小的大兴甘草、沙坡头甘草以及内蒙甘草归为另一类，幼苗的耐旱能力也低于前者，甘草生境中气候因素的水因子可能是影响其生态型分化的主导因子。
