The reaction of IR 50, TRY 3, and IR 36 cultivars of rice to R. solani challenge, the causal agent of sheath blight, and its toxic metabolite was studied. Differential response of these cultivars to ...
Every year sugar beet diseases cause lower sugar beet yields and qualities compared to the average. For that reason, high resolution field and airborne hyperspectral data is used to recognize a fungal...
2013-2014年吉林省、黑龙江省烟区首次大面积发生烟草靶斑病, 损失严重。采集吉林省柳河县、黑龙江省林口县和宾县的烟草靶斑病病叶进行分离纯化, 得到了12个菌株。将所获菌株分别与立枯丝核菌标准融合群菌株AG-2、AG-3、AG-4进行对峙培养, 结果表明:此12个菌株均与立枯丝核菌AG-3标准菌株发生融合反应, 不与其他融合群发生融合; 随机选取3个县各1个代表性菌株, 提取菌丝基因组DNA并...
Ninety eight isolates of Rhizoctonia spp. were obtained from roots of pepper (capsicum annuum L.) grown in Erzincan, Turkey during the period 2007–2008. The most prevalent multinucleate anastomosis ...
Polygalacturonase-inhibiting proteins (PGIPs) selectively inhibit polygalacturonases (PGs) secreted by invading plant pathogenic fungi. The objective of present research was to clone and introduce the...
采用烟草靶斑病菌YC-9, LJT-8和QYS-7为DNA模板,初步筛选SRAP引物组合;采用L16(45)正交试验设计,对烟草靶斑病菌的SRAP-PCR反应体系中的Mg2+、dNTPs, Taq DNA聚合酶、引物和DNA模板浓度等5个因素进行优化试验。结果表明:共筛出13对扩增条带清晰且多态性好的引物组合;烟草靶斑病菌的最佳SRAP反应体系为Mg2+浓度2.0 mmol/L、dNTP浓度200...
The α-amino nitrogen (A-N) contained in the roots and crowns of sugar beet is one of the harmful non-sugars that deteriorate the quality of sugar beet roots. This research was conducted to investigate...
A new disease of wax gourd (Benincasa cerifera Savi) characterized by scab of fruit was observed in Okayama Prefecture, Japan in July 2003. Fungal isolates frequently obtained from diseased fruits o...
Damping-off was observed on seedlings of leaf mustard, Brassica juncea (L.) Czern. var. juncea (cernua group); komatsuna, Brassica campestris L. (rapifera group); mizuna, Brassica campestris L. (jap...
A new disease of carrot (Daucus carota L.) caused by Rhizoctonia solani was found in Tokushima Prefecture in 2003 and 2004. Isolates of R. solani were obtained from carrot seedlings with damping-off...
One hundred and seventeen isolates of Rhizoctonia solanihn were obtained from creeping bentgrass [Agrostis stolonifera L. var. palustris (Huds.) Farw] and Kentucky bluegrass (Poa pratensis L.) wi...
The general inadequacy of chemical fungicides to tackle Rhizoctonia solani and Fusarium oxysporum diseases in tomato has led to the search for biocontrol solutions to these maladies. Twenty-six loca...
Effect of Potassium on damping off tobacco caused by Pythium sp and Rhizoctonia solani were investigated by giving 10, 20, 30 kg/da (5, 10, 15 ppm) K2SO4 as K2O base and pathogen inoculum at the same...
通过对四川省东、南、西、北、中5个区域、55个县(市)水稻立枯丝核菌(Rhizoctonia solani)样本进行分离、纯化和菌丝融合鉴定,发现分离得到的55株立枯丝核菌菌株除了D42菌株外,其余均属于AG1IA群。还发现其中一些菌株同时能与多个群发生融合,具有桥梁菌群属性。通过离体叶片致病力鉴定发现,各菌株间致病力差异显著。进一步的RAPD聚类分析显示,在相似系数为0.941处,该55株菌株...
  测定了8种杀菌剂(苯菌灵、甲基托布津、三氟敏、百克敏、百克敏+BOSCALID、BOSCALID、氢氧化铜和硫酸铜)不同用量对烟草猝倒病(Rhizoctonia solani)的防治效果及施用后对烟草产量和质量的影响。在温室中,用有机肥作基质播种烟草品种CTl57,将R.solani转接于水稻7d后进行接种。24h后去除接种体,在底物表面仅留下寄生物的菌丝体。在播种或刚开始表现症状时使用杀菌剂...
