The most conspicuous symptom is a frustose rootstock and decline. The suspicious infected samples were collected at different stages of growth and transported to the laboratory. The samples were rinsed under top water and disinfested with 70% ethyl alcohol. Pieces of each sample was separated with a sterile blade and cultured on potato dextrose agar (PDA) medium. Obtained fungal isolates were purified and pathogenicity of the isolates was tested by A mycelial plug (5 mm diam.) obtained from the margin of a fungal colony was placed in the wound with the mycelium facing towards the stem, and the wound was wrapped with Parafilm. Based on the morphological characteristics including colony form, conidia specific feature, and growing on agar cum Foeniculum vulgare stipes, studied fungal isolates were identified as Diaporthe novem Santos. Genomic DNA extraction was done from fungal isolates and amplification was done with ITS1, ITS4 and Bt regions primers and the amplicons were sequenced. Also the sequencing results confirmed fungal species mentioned above. This is the first report of fruit drop and dieback disease and the causal agent identification on local tangerine in north of Iran. Manuscript profile -

Host resistance is the most effective method for controlling the disease. Seedlings of some rootstocks including Minneola (C. paradise × C. reticulata), Citrus ourantium, C. lmettioides, C. aurantifolia var. Ahvazi (a natural hybrid), C. maxima, Fortunella margarita, C. medica, C. medica var. Otroj, C. lemonia var. Lisbon, C. taivanica, C. volkameriana, C. lemonia var. Eureka, C. aurantifolia, C. grandis, C. lemonia var. Rough Lemon, C. macrophylla (Alemow), Poncirus trifoliata, Swingle Citromelo(C. paradise × P. trifoliata) were evaluated for their resistance to the citrus nematode. The seedlings were planted in the pots and citrus orchard. In case of pot experiments, the three months old rootstock seedlings were transplanted to the pots with 40 J2/g of soil. The roots of seedlings were scored for nematode infestation after six months. For orchard experiments, the five months old rootstock seedlings were transplanted to naturally infested soil in a citrus orchard with 25 J2/g of soil. The roots of these seedlings were evaluated for nematode infestation 4.5 and 15 months after transplanting. The susceptibility of rootstocks to citrus nematode was evaluated on the base of the number of penetrated females per gram of feeder roots. In both experiments P. trifoliata, Swingle citromelo and Citrus ourantium were resistant to citrus nematode, whereas the other rootstocks supported a high population of the nematode.

In this regard, the combination of three rootstocks (Dashtestan, Doraheh, and Mond) and four grafts (Raad, Metin, Superchief, and Rockstone) were examined and after grafting, vegetative and reproductive traits and biochemical traits were measured. The results showed that different bases had a significant effect on the measured traits. According to the main effect of base, the highest percentage of success (up to 50%) was obtained using Dashestan base, while the lowest (40%) was observed in Mond base. On the other hand, there were significant interactions between root and scion in terms of parameters of days to flowering, plant height, average fruit weight, firmness, protein, lycopene, carotenoid, catalase and superoxide dismutase. Finally, it can be concluded that the best base and scion combinations were Raad and Superchif respectively on Dashtestan base, because in many parameters evaluated, these base and scion combinations were better than other combinations.Findings: The results showed that different bases had a significant effect on the measured traits. According to the main effect of base, the highest percentage of success (up to 50%) was obtained using Dashestan base, while the lowest (40%) was observed in Mond base. Manuscript profile -

This research was performed first to recover oomycete species from infected apple roots and crowns, second, establish a reliable method for inoculation of apple rootstocks and third, evaluate disease resistance of some apple rootstocks in tissue culture media. Different infected samples were collected from the Horticultural Research Stations of Seed and Plant Improvement Institute in Karaj. Three Phytophthora cactorum isolates in addition to one Pythium sp. isolate were recovered out of 20 samples using semi selective media containing Carbendazim, Pimaricine and Rifampicin, 10 mg per liter each. Pathogenicity test was carried out on unripe pear fruits. For disease resistance evaluation experiments, five apple hybrid progenies (H1-H5) obtained through crossing between local genotype Morabbai mashhad and M9 plus the parents, M26, MM106 rootstocks and local genotype Azayesh were assessed to Phytophthora in tissue culture jars. Plant materials were micropropagated on QL media and inoculated with P. cactorum. The pathogen was amplified on the wheat grains so that the pathogen incited necrosis on the shoots inside the jars. The extent of necrosis was recorded after 18 days. Hybrid H5 was assessed as the most sensitive genotype to P. cactorum while hybrid H1 showed high level of resistance reaction. Manuscript profile -

Meanwhile, in some pomegranate orchards, salinity stress is one of the abiotic stresses that harm agricultural crops such as pomegranate production by reducing productivity. This research aims to compare growth characteristics between selected genotypes including 1- Chah Afzal 2- Vahshi Babolsar, 3- Narak Lasjerd Semnan 4- Poost Siahe Yazd, 5- Malase Yazdi, 6- Rababe Neyriz, under salinity stress, in a randomized complete block design with three replicaions at Chah Afzal research station of Ardakan city. During the whole experiment, the trees were irrigated with saline water with salinity of 9 ± 0.5 dS/m every 12 days. Based on the results of this research and considering the lowest amount of ion leakage, the highest content of relative humidity and potassium, the high amount of total chlorophyll, carotenoid and leaf surface ratio, the lowest sodium to potassium ratio and necrosis percentage Chah Afzal genotype showed very good resistance to salinity conditions, followed by Poost Siahe Yazd, Vahshi Babolsar, Narak Lasjerd, Malase Yazdi and finally Rababe Neyriz were highly sensitive to salinity. According to the results of cluster analysis, the highest similarity between genotypes based on the parameters mentioned above was between the Narak Lasjerd and Malase Yazdi. The highest difference between Chah Afzal genotype and other genotypes was registered. This shows a significant difference in the superiority of Chah Afzal genotype over other genotypes in total traits. Therefore, due to the compatibility and proper growth of these genotypes in saline conditions, it is suggested that they could be used as a rootstock and the cvs. Malase Yazdi and Rababe Neyriz, which also produced flowers and fruits in saline conditions, can be grafted on them.

A Split Plot experimental des MoreFruit productivity and quality of eight years peach and nectarine cultivars (Rich Lady, Ryan Sun, Ruby Diamond and Venus) grafted onto Cadaman-Avimag, Viking, Atlas, GxN 15, GF 677, MRS 2/5 and Nemaguard (control) rootstocks were evaluated. A Split Plot experimental design was used, with each rootstock/scion combination as an experimental unit. Total yield, fruit size distribution, number of fruit, and fruit weight were recorded. Fruit quality parameters including soluble solids concentration (SSC), blush color development, and flesh firmness were also measured. On average, Cadaman yielded the greatest fruit weight and number of fruit, compared with the control, followed by GxN 15, Atlas and GF 677 to a lesser degree, while Viking was similar to the Nemaguard control, and MRS 2/5 yielded less than the control. There were no great differences between the rootstocks and the control with respect to fruit size and weight, although the most vigorous, Cadaman and GxN 15, were significantly higher (190.1 and 197.2 g, versus 179.5, respectively). For fruit quality parameters, Viking had the highest accumulation of SSC with respect to Nemaguard and MRS 2/5 had the highest percentage of blush color compared with the control. For flesh firmness at harvest, GF 677 was the firmest and MRS 2/5 was the softest. Manuscript profile -

12 - Changes in Some Physiological and Biochemical Characteristics of the Selected of Almond Cultivars (Prunus dulcis Mill.) Grafted on Different Rootstocks Under Drought Stress
Abdolbaset Ranjbar Ali Imani saeed piri Vahid AbdoosiIn order to evaluate the response of selected cultivars of almond, grafted on different rootstocks under drought stress due to increased irrigation intervals in the 2015-2016 year, in the Temperate Fruit Research Center, Horticultural Research Institute in Karaj, a fact MoreIn order to evaluate the response of selected cultivars of almond, grafted on different rootstocks under drought stress due to increased irrigation intervals in the 2015-2016 year, in the Temperate Fruit Research Center, Horticultural Research Institute in Karaj, a factorial based on a randomized complete design with three replications was carried out. Factors comprised cultivars in five levels (Supernova, Texas, Marcona, Shokoufeh and K13-40), rootstocks in Three levels [peaches × almonds hybrids (GF-677 and GN-22), and bitter almond seedlings NO. 32], and drought stress in four levels (irrigation intervals were 3(Control), 5, 10 and 15 Days). The results showed that the interaction of three factors for chlorophyll fluorescence parameters include maximum (Fm), variable (Fv) and variable to maximum (Fv/Fm), electrolyte leakage and releate water content(RWC) of leaves at 1% probability level, and interaction effects of rootstock × cultivar for chlorophyll b and a/b as well as cultivar × drought stress for a/b were significant at 5% probability level. Also, interaction effects of rootstock × drought stress were significant for all evaluated traits except a/b at 1% probability level. Drought stress reduced Fv by increasing Fo and decreasing Fm, and reduced Fv/Fm in sensitive cultivars on seedling and GN-22 rootstocks from 0.82 to 0.67. As a general result, all of the cultivars on the GF-677 rootstock showed greater resistance to drought stress. Supernova and Shokofeh cultivars grafted on GF-677 rootstock were most resistant rootstock - scion compounds, but other rootstock-scions compounds, were sensitive to drought stress.

16 - The Effects of Various Concentrations of IBA Hormone on Rooting of ‘TF92’; New Peach-Almond Hybrid under Ex- vivo and In - vitro Conditions
Ruhollah Haghi Ali Imani Ali Torkashvand Marzieh Ghanbari JahromiOne of the main problems of fruit cultivation, especially peaches and almonds, is the lack of the application of the existing clone rootstocks such as the promising hybrid of peaches and almonds and its unavailability due to its propagation in Iran. So the seedling root MoreOne of the main problems of fruit cultivation, especially peaches and almonds, is the lack of the application of the existing clone rootstocks such as the promising hybrid of peaches and almonds and its unavailability due to its propagation in Iran. So the seedling rootstocks are inevitably used. However these rootstocks cause many problems for the growers due to the lack of uniformity. In order to solve this problem, the effect of different concentrations of indole butyric acid on the rooting of hardwood cuttings ‘TF92’ (promising hybrid of peach and almond) was tested in a private sector greenhouse in Karaj equipped with a heating pad during 2019. In this paper, the effect of 4 different levels of indole butyric acid hormone (IBA) 0, 1500, 2500 and 3500 parts per million in solution on hardwood cuttings was studied in a completely randomized design in three replications. The results showed that there was a significant difference between various concentrations of indole butyric acid in terms of the effect on the characteristics of the mode of investigation such as the percentage of rooting, the number of roots formed, the dry weight of the roots, the length of the roots and the length of the resulting branches in the cuttings. Thus the highest rooting percentage (78.45) was found in the indole butyric acid (IBA) hormone treatment with a concentration of 2500 mg L-1 compared to other treatments. Therefore, this method can be recommended as a suitable treatment for the rooting of wood cuttings of this promising emerging rootstock. Also, the highest percentage of rooted plantlets was obtained on Murashige and Skoog medium (MS) supplemented with 1 mg L-1 IBA. According to this study, the concentrations of 1 mg L-1 IBA results in the maximum rooting, and it has been suggested as a suitable hormone for in vitro rooting of ‘TF92’. Manuscript profile -
