Identification and resistant characterization of legume sources against Meloidogyne incognita

Root-knot nematodes(RKNs; Meloidogyne spp.) are becoming a serious problem in legume production. This study identified Vigna genotypes exhibiting resistance to M. incognita(RKN) and characterized the modes of the resistance to M. incognita. In total, 279 accessions from 21 Vigna species were screened for resistance based on a galling index(GI) and an egg mass index(EI). Seven accessions were highly resistant to RKN with GI≤25, namely JP74716(V. mungo var. mungo; cultivated black gram), JP107881(V. nepalensis), JP229392(V. radiata var. sublobata; wild mungbean), Aus TRCF118141(V. unguiculata subsp. unguiculata; cultivated cowpea), Aus TRCF306385(V. unguiculata subsp. unguiculata), Aus TRCF322090(V. vexillata var. vexillata; wild zombi pea) and JP235929(V. vexillata var. vexillata). JP229392 and Aus TRCF322090 were the most resistant accessions having EI values of 18.74 and 1.88, respectively. Continuous culture of M. incognita on both JP229392 and Aus TRCF322090 resulted in a weakness in pathogenic ability for this RKN. The resistance in JP229392 and Aus TRCF322090 to RKN appeared to be antibiosis that was associated with reduced nematode penetration, retardation of nematode development and impeding giant cell formation. The Vigna germplasm resistance to RKN identified in this study could be utilized as gene sources for the development of RKN-resistant Vigna cultivars.

Response of yield,quality, water and nitrogen use efficiency of tomato to different levels of water and nitrogen under drip irrigation in Northwestern China

The objective of this study was to investigate the effects of applying different amounts of water and nitrogen on yield, fruit quality, water use efficiency(WUE), irrigation water use efficiency(IWUE) and nitrogen use efficiency(NUE) of drip-irrigated greenhouse tomatoes in northwestern China. The plants were irrigated every seven days at various proportions of 20-cm pan evaporation(E_p). The experiment consisted of three irrigation levels(I1, 50% E_p; I2, 75% E_p; and I3, 100% E_p) and three N application levels(N1, 150 kg N ha~(–1); N2, 250 kg N ha~(–1); and N3, 350 kg N ha~(–1)). Tomato yield increased with the amount of applied irrigation water in I2 and then decreased in I3. WUE and IWUE were the highest in I1. WUE was 16.5% lower in I2 than that in I1, but yield was 26.6% higher in I2 than that in I1. Tomato yield, WUE, and IWUE were significantly higher in N2 than that in N1 and N3. NUE decreased with increasing N levels but NUE increased with increase the amount of water applied. Increasing both water and N levels increased the foliar net photosynthetic rate. I1 and I2 treatments significantly increased the contents of total soluble solids(TSS), vitamin C(VC), lycopene, soluble sugars(SS), and organic acids(OA) and the sugar:acid ratio in the fruit and decreased the nitrate content. TSS, VC, lycopene, and SS contents were the highest in N2. The harvest index(HI) was the highest in I2N2. I2N2 provided the optimal combination of tomato yield, fruit quality, and WUE. The irrigation and fertilisation regime of 75% E_p and 250 kg N ha~(–1) was the best strategy of water and N management for the production of drip-irrigated greenhouse tomato.

东北地区人参锈腐病菌的分子鉴定

人参锈腐病一直是人参生产中的重要病害之一,严重影响人参产业的持续健康发展。为明确东北人参主产区人参锈腐病的病原菌种类,从辽宁、吉林和黑龙江省人参主产区罹病植株上共分离纯化获得菌株45株,采用rDNA-ITS序列分析方法鉴定了东北人参主产区人参锈腐病致病菌,在PDA培养基上观察病原菌菌落及分生孢子形态特征,通过针刺离体接种法测定不同种间的致病力差异。结果表明:在45个菌株中,28个菌株为毁灭柱孢(Cylindrocarpon destructans),rDNA-ITS序列与GenBank中的C.destructans相似性达99%,菌落呈浅褐色,质地毡状,分生孢子圆柱型,直立,基部稍窄;3个菌株为毁灭柱孢毁灭变种(Cylindrocarpon destructans var. destructans),rDNA-ITS序列与GenBank中的C. destructans var. destructans相似性达99%,菌落呈深褐色,质地绒毛状,分生孢子棍棒型,稍弯曲,基部钝圆;14个菌株为强壮土赤壳(Ilyonectria robusta),rDNA-ITS序列与GenBank中的I. robusta相似性达99%,菌落呈棕灰色,质地毛絮状,分生孢子长椭圆形,稍弯曲,两端钝圆。生长11d后的菌落直径为(4.21±0.16)～(7.78±0.25)cm,其中生长速度最快的病原菌为强壮土赤壳(I. robusta),其次为毁灭柱孢(C. destructans),毁灭柱孢毁灭变种(C. destructans var. destructans)生长速度最慢。致病力测定结果表明,不同种间致病力差异显著,毁灭柱孢毁灭变种(C. destructans var. destructans)致病力最强,其次为毁灭柱孢(C. destructans),强壮土赤壳(I. robusta)相对较弱。     

NaCl和Na2CO3胁迫对5种鸢尾属植物生长的影响

为探明5种不同鸢尾属植物黄菖蒲(Iris pseudacorus)、花菖蒲(I.ensata var.hortensis)、溪荪(I.sanguinea)、马蔺(I.lactea var.chinensis)和喜盐鸢尾(I.halophila)对盐胁迫的耐受能力,采用溶液培养研究了不同浓度NaCl和Na2CO3胁迫对5种鸢尾属植物外在形态、生长以及存活率的影响.结果表明:在低浓度(0.3％)NaCl胁迫下,5种鸢尾属植物生长健壮,无任何盐害症状;中度浓度(0.6％～1.2％)NaCl胁迫下,黄菖蒲、溪荪和花菖蒲生长变化均相对较平缓,增幅不大,且胁迫浓度越大,胁迫时间越长,其生长受抑现象越明显;而喜盐鸢尾和马蔺无论是叶片还是根系即使在高浓度(1.5％～ 1.8％)NaCl下也均基本保持稳定的增长幅度,二者存活率分别达74％和80％,其他3种鸢尾在此高浓度盐胁迫下植株全部死亡,表明高浓度NaCl胁迫下的马蔺和喜盐鸢尾抗NaCl能力最强.另外,不同浓度Na2CO3处理28 d,即使在最低浓度(0.1％)胁迫下盐害均达到Ⅲ～Ⅳ级,而在高Na2CO3浓度下,5种鸢尾属植物大部分死亡.说明Na2CO3较NaCl对参试鸢尾属植物具有更大的毒害作用.
