Respuesta de cuatro genotipos de vid (Vitis spp.) a deficiencias de hierro directas o inducidas por bicarbonato

In Turkey, calcareous soil conditions usually cause significant decreases in grape yield. Understanding the physiological responses of grapevine genotypes under such conditions would yield invaluable knowledge to recover these problems. This study was thus conducted on the comparative evaluation of the responses of four Vitis spp. materials (a cultivar, 'Alphonse Lavallee', and three rootstocks, 'Fercal', '99 R' and '1613 C'), differing in tolerance potential to direct and lime-induced chlorosis. In greenhouse, rooted cuttings were grown in inert perlite using containers for two years with complete Hoagland nutrients solution except for Fe as variable. The experiment comprised five applications performed for three times per year. Iron applications (FeNaEDTA) in 9 and 36 mg L–1 doses and their combinations with 840 mg L–1 NaHCO3 were compared with control (iron-free Hoagland solution). FeNaEDTA addition into nutrient solution induced significant increases in iron and chlorophyll contents across the genotypes. The highest Fe level was determined in 'Fercal' (169.8 mg kg–1) with 36 mg L–1 FeNaEDTA. Bicarbonate additions restricted the vegetative development of '1613 C'. For instance, iron content of '99 R' was 137.9 mg kg–1 when treated with 9 mg L–1 FeNaEDTA, whereas the iron value reduced to 73.9 mg kg–1 when NaHCO3 was added. 'Alphonse Lavallée' and 'Fercal' displayed their lime-tolerances by exhibiting little reduction of both iron and chlorophyll contents. Therefore, 'Fercal' would be proven as a favorable rootstock for regions with calcareous soil. Tolerance to NaHCO3-induced Fe shortage appeared to be genotype-dependent. Chlorophyll content of young leaves positively correlated with Fe concentration, indicating the vital role of iron in chlorophyll content of leaves.Los suelos calcáreos causan normalmente disminuciones significativas en la producción de vid en Turquía. Para manejar este problema es importante conocer las respuestas fisiológicas de los genotipos de vid en tales condiciones. El presente estudio se condujo para evaluar comparativamente las respuestas de cuatro genotipos de Vitis spp. (un cultivar, 'Alphonse Lavallee', y tres portainjertos, 'Fercal', '99 R' and '1613 C') con diferente tolerancia potencial a la clorosis directa o férrica. Se cultivaron durante dos años consecutivos, en contenedores de perlita inerte en invernadero, esquejes enraizados con una solución completa de nutrientes de Hoagland, con el Fe como factor variable, mediante cinco aplicaciones realizadas tres veces por periodo vegetativo. Se compararon aplicaciones de hierro (FeNaEDTA) a dosis de 9 y 36 mg L1 combinadas con 840 mg L1 de NaHCO3 con el grupo control (solución Hoagland sin Fe). La adición de FeNaEDTA en la solución nutritiva indujo un incremento significativo en los contenidos de Fe y clorofila de los genotipos. El nivel más alto de Fe se detectó en 'Fercal' (169,8 mg kg1) con 36 mg L1 de FeNaEDTA. La adición de bicarbonatos restringió el desarrollo vegetativo de '1613 C' (el contenido de Fe en '99 R' fue 137,9 mg kg1 cuando se trató con 9 mg L1 de FeNaEDTA, y de 73,9 mg kg1 cuando se añadió NaHCO3). 'Alphonse Lavallée' y 'Fercal', tolerantes a la clorosis férrica, presentaron una disminución en su contenido en Fe y clorofila. 'Fercal' resultó ser un portainjerto favorable para regiones con suelos calcáreos predominantes. La tolerancia a escasez de Fe inducido por NaHCO3 parece ser dependiente del genotipo. El contenido de clorofila de las hojas jóvenes correlacionó positivamente con la concentración de Fe, indicando el papel vital del Fe en el contenido de clorofila en las hojas

Detection of the Mi-1.2 gene for resistance to root-knot-nematode (Meloidogyne javanica (Treub, 1885) Chitwood) in tomato by SCAR marker, Mi23

WOS: 000300345400013Detection of the Mi-1.2 gene for resistance to root-knot-nematode (Meloidogyne javanica (Treub, 1885) Chitwood) in tomato by SCAR marker, Mi23 Root-knot nematodes have wide range of host plants and cause important yield looses in many crop plants. The resistance gene Mi was introduced to the cultivated tomatoes from wild tomato species Solanum peruvianum in 1940. The gene confers resistance to Meloidogyne arenaria (Neal, 1889) Chitwood, Meloidogyne incognita (Kofoid & White, 1919) Chitwood and Meloidogyne javanica (Treub, 1885) Chitwood. Present study was carried out in Plant Protection Research Institute of Adana in 2010. In the study tomato plants were inoculated by M. javanica (1000 larva per plant) and resistance features of the genotypes were screened by classical method. Furthermore those tomato genotypes were screened for their resistance as susceptible, homozygot or heterozygote resistant by using REX-F1-REX-R2 and Mi23F-Mi23R specific primers According to the classical tests results the root-gall index values were determined as lower than 2 in resistant plants and higher than 2 in susceptible ones. Reproduction factors were observed 0 and more than1 in resistant and susceptible plants respectively. The data showed a clear correlation between classical screening and the used of DNA markers. It was concluded that those markers could be used in marker assisted selection for M. javanica resistance breeding

The effects of different nitrogen doses on yield, quality and leaf nitrogen content of some early grape cultivars (V. vinifera L.) grown in greenhouse

Nitrogen deficiency is a worldwide problem, causing restrictions in productivity of many horticultural produces. Particularly, the issue is compounded when the greenhouse production is employed. Therefore, reliable knowledge on proper application of nitrogen ensures not only satisfactory yield but also balanced vegetative and reproductive growth in plants. This study was thus conducted to investigate the effects of different nitrogen doses (10, 20 and 30 kg N da-1) on some quality properties with petiole nitrogen content of grape cultivars 'Early Cardinal' (EC), 'Yalova Incisi' (YI) and 'Ergin Cekirdeksizi' (ER) grown in plastic greenhouse for two years. Overall results indicated that cluster weight, cluster length and yield values increased depending on the nitrogen doses. On the other hand, increasing nitrogen applications generally resulted in higher petiole nitrogen content. The highest petiole nitrogen values were obtained from the treatment of 30 kg N da-1 for two phenologycal periods (1.29 and 1.59% for full bloom and veraison, respectively). Considering the general investigations, 20 kg N da-1 application could be recommended in terms of nitrogen supply under such conditions. © 2010 Academic Journals

Effects of boron on yield, quality and leaf nutrients of Isabella (Vitis labrusca L.) grape cultivar

The present study was conducted in 2014 vegetation season in a vineyard of Giresun Hazelnut Research Institute. Isabella (Vitis labrusca L.) grape cultivar were treated with four different boric acid (H3BO3) doses (control, 0.1%, 0.2%, 0.3%) at two different periods (a week before and after full-bloom). The effects of foliar boron treatments on yield, quality and leaf nutrients were investigated. Boric acid treatments positively influenced cluster weight, width and volumes and increasing values were observed with increasing boron doses. Boric acid treatments also influenced berry homogeneity and yielded more homogeneous appearance. Chlorophyll contents increased with increasing boron treatments. The greatest yield, cluster length, cluster volume, cluster size, cluster width, berry width and leaf area were obtained from 0.3% boric acid treatments. In general, leaf nitrogen, phosphorus, calcium, magnesium, zinc and copper concentrations increased, but potassium and iron concentrations decreased with increasing boron doses. As compared to control treatment, all treatments had broader leaf sizes and higher chlorophyll contents. Especially 0.3% boric acid treatments had quite positive influences on quality, size and color homogeneity. Considering the nutrients and pH level of experimental soils, it was concluded that foliar nutrient treatments may support plant growth and development and 0.3% boric acid treatments were recommended for high quality and quantity yields in Isabella grape cultivar

Effects of silver nitrate and donor plant growing conditions on production of pepper (Capsicum annuum L.) haploid embryos via anther culture

The responses of pepper anthers to different concentrations of silver nitrate and in dependence of the donor plant growing conditions were studied for haploid embryo production via anther culture. U-247 and U-238 genotypes, which were selected from a local paprika pepper population, were used as plant materials. Flower buds were collected from the plants grown either in greenhouse or in open field conditions. Four different silver nitrate concentrations (5, 10, 15 and 20 mg l-1) were tested. Haploid embryos were obtained from all the concentrations tested, but with different production rates. The highest embryo formation (45.7 embryos per 100 anthers) was obtained from the genotype U-247 in the medium containing 15 mg l-1 silver nitrate. The anthers taken from the plants grown in the greenhouse produced more embryos than that of the open field conditions
