Therefore control of this disease through effective vaccination programs is very important. The objective of this study was to compare the effectiveness of La Sota and Avinew vaccines in broiler chicks. In this study, 270 day old Ross broiler chicks were divided into 3 groups with 3 replicates in each group and 30 chicks in each replicate. Avinew and lasota vaccines were used in groups 1 and 2 respectively. Group 3 was the covered group and Newcastle vaccine wasn't used in this group. Breeding conditions were the same in the 3 groups and blood samples were collected the 3 groups and blood samples were collectd on days 1,14,24,34 and 44 for determination of antibody titers obtained from Newcastle vaccines using the ELISA serologic test. The results indicated that in the vaccinated groups, antibody titers increased significantly (v<0.05) after day 14 in comparison to the control group. In the control group, the antibody titer belonging to maternal immunity decreased significantly (p<0.05) after day 14 and the chicks became susceptible to Newcastle disease. Antibody titers obtained from the two vaccines significantly different (p<0.05) but due to less adverse reactions following vaccination, the Avinew vaccine is preferred over the lasota vaccine.

The experiment was performed as randomized complete block design with three replications of for 47 days in a sheltered place in Tonekabon plain (north of Iran). Results showed that the source of the cutting on germination percent, germination speed, mean germination time and germination power, and the effect of hormone on germination speed were significant. Stimulation of germination at both cutting sources started after 24 days of planting and ended during three weeks. The shoot cuttings imbibed with 3000 mg/l IBA and the sucker cuttings imbibed with 5000 mg/l IBA caused germination of 91/66 and 100 percent, respectively. Regardless of cutting source, the cuttings imbibed with 3000 and 5000 mg/l were more favorable for germination speed. During this period, no rooting occurred in cuttings. It is recommended for rooting of large-leaf linden cutting (especially with the sucker source), the humidity and heat of greenhouse and soil of pots to be more closely monitored by future researchers.

Because they contain a variety of chemical compounds such as pigments, vitamins, and enzymes, theses microorganisms have found many applications in the industry. Several studies have reported that cyanobacteria can improve the plant growth by improving the soil structure as they have potential to secrete extracellular polysaccharides that help in soil aggregation and water retention. Numerous plant-associated bacteria produce auxin and related indolic compounds. The role of microorganisms as plant growth stimulators is widespread in nature, especially in relation to the production of phytohormones. Auxins represent a group of plant hormones that are implicated in the regulation of diverse biological processes. The aim of this research was to study the production capability of auxin and some photosynthesis pigments in heterocystous cyanobacteria serovars isolated from paddy fields in eastern part of Mazandaran. After collecting soil samples, cyanobacteria cultures were cultivated on a typical BG110 medium, for purification purposes, repeated sub-culturing was carried out on solidified and liquid medium before the strains were characterized morphologically. Results indicated that a great range of isolated cyanobacteria had the potential to produce auxin as a main factor for improving plant growth and there were significant differences in the chlorophyll and carotenoid contents; however, potential of each species according to different ecological diversity and genus were different. Maximum chlorophyll, carotenoid, and auxin contents were observed in MGCY277 (Lyngbya diguetii), MGCY497 (Nostoc ellipsosporum), and MGCY358 (A nabaena variabilis) serovars, respectively.

This study was conducted to compare the immunogenicity of live and killed Newcastle disease vaccines by measuring the hemagglutination-inhibiting antibodies in the sera of broiler chicks. For this, 270 day-old chicks (Ross) were allocated to 6 match-weighted groups (A through F). Group A was non-vaccinated control; group B received B1 and Clone 30 live vaccines by eye-drop at days 10 and 31, respectively; groups C and D were injected subcutaneously with killed vaccine at days 3 and 10, respectively; groups E and F received killed vaccine at days 3 and 10, respectively, and were also given live vaccines according to group B. From each group, four chicks were randomly selected and bled on day 3, and also 12 chicks on days 10, 17, 24, 31 and 38. Then, the collected sera were assessed by hemagglutination-inhibition (HI) test. The results show that up to day 17, there was no significant difference in HI titers among experimental groups; compared with groups which received killed vaccine only, groups given live vaccines had a significantly higher antibody level at days 31 and 38. In conclusion, live Newcastle disease vaccines, even if not repeated, give better immunity when compared to killed vaccine, and if they were used together the immune response would be stronger.

Experiment was as a factorial based on a randomized complete block design with three replications. Seed priming was considered at 4 levels (hydro-priming, auxin solution, nitroxin solution and without priming) and water stress at 3 levels (no-water stress, stresses at the shoot growth stage and seed filling stage). Results showed that plant growth rate, plant height, number of branches, head diameter, head number, 1000-seed weight, yield and the percentage of seed kernel weight were significantly affected by seed priming and water stress. Yield indicated positive correlation with measured growth characteristics, but the highest observed with the percentage of seed-kernel weight. Maximum yield obtained from auxin and nitroxin seed priming by 1852.8 and 1818 kg.ha-1, respectively. Totally, seed priming caused to improve in growth characteristics, but auxin and nitroxin effects were better than hydro-priming. Also, no-water stress had the highest yield by 1846.8 kg.ha-1 in comparison with water stresses. Generally, results showed that priming in normal irrigation conditions caused to maximum yield.

In this regard, vaccination is considered to be the most effective method to prevent disease, which unfortunately, in some cases, vaccination has caused damage to the industry and subsequently dissatisfaction of livestock farmers. The purpose of this study is a comparative evaluation of the types of complications caused by the injection of different types of FMD vaccines available in the country. Materials and methods: The current study was conducted in the field and data collection, between March 2015 and March 2021, on the adult population of large and small ruminants in Alborz, Ilam and provinces. It has been done on 9 different vaccines. Results: The results showed that the cumulative side effects caused by the injection of vaccines was not significant (p>0.05), while the separate side effects of vaccines number 1, 5 and 7, were significant (p<0.05). Conclusions: The results of the study indicated that significant side effects have no important clinical values and counted as the natural reactions of any vaccine. In addition, it was concluded that the Iran made vaccines can be very useful and beneficial in disease prevention and control. Manuscript profile -

One minute pretreatments including auxin regulators NAA, IBA and IAA at a concentration of 500 mg / l and treatments containing GA, IAA, IBA and NAA, 250 mg / l were compared with each other and with control plants. Stems and roots fresh weight, dry weight, dry weight percentage, total photosynthetic pigments content as well as total terpenoids were measured. Fresh and dry weight and the percentage of dry weight of stem did not show sensitivity to the treatments and pretreatments, and the effects were not significant. NAA treatment had the most positive effect on roots fresh and dry weight, although the percentage of root dry weight was not significantly affected by the treatments. The highest significant increase in terpenoid content was observed in NAA treatment and NAA and IBA pretreatments. GA treatment had the most positive effects on the content of each of chlorophylls a and b, total and carotenoid content. In terms of effect on photosynthetic antenna composition, the most positive effects on the ratio of total chlorophyll to carotenoids were observed in GA, NAA, IAA and IAA pretreatments. IAA treatment also showed a significant increase in chlorophyll a to b ratio. The correlation between growth parameters with each other and also the correlation of chlorophyll content with each other and with carotenoids was positive and significant. However, the correlation of terpenoid content with none of the other traits was significant. On the other hand and from an application point of view, based on gas chromatography-mass spectrometry measurements, naphthalene-acetic-acid treatment was effective in severely increasing the content of valuable medicinal compound, bis-2-ethylhexyl phthalate, compared to the control.

Spraying was done using IAA and BAP in the rates of 100, 200 and 300 ppm. Application of IAA and BAP promoted plant height and branches length. However, the branches length was increased in low IAA concentrations. Leaf chlorophyll content was in maximum at 300 ppm of BAP and 100 ppm of IAA. Application of IAA increased canopy diameter. More IAA concentrations increased shadow diameter. Increasing in IAA concentrations caused reduction in node number. Number of lateral shoots increased in high concentration of BAP in addition, more plant biomass was produced in high concentrations of BAP and IAA. Foliar application of BAP caused increasing in number of leaf comparing IAA. Therefore, application of IAA and BAP can be considered as an appropriate option to improve yield in lemon balm.

Auxins and cytokinins are usually known to be stimulator for cell division and differentiation and plant organ development. The current study has been carried out to investigate the effect of foliar spraying of indole acetic acid (IAA) and benzyl amino purine (BAP) in concentrations of 100, 200, and 300 mg/L based on completely randomized design on evening primrose as a pot experiment. Spraying with both plant hormones especially BAP could be positively efficient on most of evaluated traits improvement. Higher concentrations were more effective on plant growth indices. The improving effect of BAP on aerial organs growth was more conspicuous; however, IAA was more effective on underground part. Therefore, to improve evening primrose growth, spraying with 300 mg/L of BAP or IAA would be recommendable. Manuscript profile -

Leafy semi-hardwood cuttings of bottle brush were taken from mother plants in the last week of September 2010. These cuttings were treated with 0 (control), 2000, 3000 and 4000 mg/L Indole-3-butyric acid or Naphthaleneacetic acid and then were placed on a sandy rooting bed under mist or polyethylene tent conditions. Experiment was carried out as factorial based on a randomized complete block design with five replications. Cuttings treated with 4000 mg/L Indole-3-butyric acid showed the highest rooting percentage (62%). Cuttings treated with 4000 mg/L Indole-3-butyric acid or Naphthaleneacetic acid also produced the most number of roots. Mean root length and mean dry weight of bottle brush cutting roots were the highest when they were treated with 4000 mg/L Indole-3-butyric acid and were placed under polyethylene tent. Rooting percentage, leaf and root number and new growth of buds of bottle brush cuttings treated with auxin were significantly higher when they were placed under mist condition instead of polyethylene tent. However, even polyethylene tent was better than control in root length and root dry weight of bottle brush cuttings. In conclusion, treating bottle brush cuttings with 4000 mg/L Indole-3-butyric acid or Naphthaleneacetic acid under mist condition was recommended in order to rooting increment. Manuscript profile
