This experiment was carried out to determine the percentage of internal connection between rootstock and scion in graft union with nondestructive and noninvasive MRI (Magnetic Resonance Imaging) method and to follow performance status according to internal connection ratios of the grafted rooted vines after planting to vineyard field. Research was established in a factorial randomized block design and carried out with cvs. Merlot and Syrah grafted onto 110?R rootstock and 4 different internal (MRI) connection levels in 3 replications. The percentages of grafted rooted vine internal determination by MRI by four sides (13.75%) in graft union were found to be very low than others at the pre-planting stage. An increase in the internal connection ratio in the majority of the grafted rooted vines was determined after the vegetative growth phase. Therefore, the internal connection ratios of the graft union of rooted vines of cvs. Merlot and Syrah varieties showed a tendency to increase during the second year of development. Again in both cultivars, loss rate of grafted rooted vines showed a decreasing tendency depending on increase of internal connection ratio of graft union. As a result, in case of decrease of MRI costs, it is thought that grafted rooted vine producers may have the opportunity to supply better quality seedlings to vine growers using MRI techniques. 相似文献
The objectives of this study were to examine the free radical scavenging activity and the protective effects against macromolecular
oxidation as well as the cytotoxic activity of Aphanes arvensis aqueous and methanolic extracts. Free radical scavenging activity was determined by DPPH method. The methanolic extract showed
a scavenging activity nearly equivalent to Trolox and Vitamin C and has an IC50 value of 4.54 μg/mL. Total antioxidant capacity was determined by CUPRAC method. The antioxidant capacity of aqueous and
methanolic extract was 0.792 and 1.550 mmol TE/g DWE, respectively. The protective effect of A. arvensis extracts against lipid peroxidation was evaluated using a liposome oxidation system. The methanolic extract was more active
than the aqueous extract. The aqueous extract possessed protective effect against protein oxidation in a dose dependent manner.
Both extracts showed inhibitory effect on DNA oxidation as measured by plasmid relaxation assay. Results presented here indicate
that A. arvensis possess strong antioxidant activity and protective effects with very little cytotoxic effect, and they can therefore be used
as a natural additive in food, cosmetic and pharmaceutical industries. 相似文献
In this study, the intention was to investigate the chemical and sensorial changes occurring during cold storage (4 ± 1°C)
of caviar obtained from rainbow trout Oncorhynchus mykiss W. 1792 that was dry salted in different ratios. Caviar has a higher fat and protein content than other seafood products,
and in processing it with dry salting technology, it was determined that the shelf life could be up to 28 days for the experimental
group in which salt was applied at a rate of 4% and up to 35 days for the experimental group in which salt was applied at
a rate of 8%. Thus the storage period of the samples is longer for the products to which a high (8%) amount of salt was applied
than the products to which a low (4%) amount of salt was applied in the salting process. 相似文献
In this study, the influence of an agricultural liquid organic fertilizer on growth and biomass composition of Spirulinaplatensis Geitler was studied. In the first trial, five concentrations of organic fertilizer were arranged, e.g., 0.1, 0.25, 0.5, 1 and 2?ml/l, in which no other extra nutrients except bicarbonate were used. Maximum dry weight, chlorophyll a and specific growth rate were achieved in control group. In the second trial, initial fertilizer levels of the three groups were 0.1?ml/l and all groups contained sodium bicarbonate. One of the groups had 2.5?g/l NaNO3, while the other was supported with 0.1?ml/l fertilizer by two-day intervals to see the effect of nitrogen. In order to understand the effects of phosphate, 0.4?g K2HPO4 was added to the other group as well as 2.5?g NaNO3. Between the experimental groups, the highest chlorophyll a value was found in control group as 53.97?mg/l. The chlorophyll value at group II (37.65?mg/l) was lower than the control group. The maximum dry weight and crude protein recorded in control group were 1,330?mg/l and 60.17%, respectively, when compared with 1,256?mg/l and 59.92% in group II. No significant differences were observed in crude protein values of Spirulina grown in control and group II (P?<?0.05). Consequently, it was seen that commercial liquid organic fertilizers may be replaced by Zarrouk??s medium except for nitrate, phosphate and bicarbonate in S. platensis cultures in order to decrease the production costs. 相似文献
The aim of the present study was to determine the effect of various cryoprotectants on post-thaw sperm quality and fertilizing capacity of cryopreserved scaly carp (Cyprinus carpio) semen. The present study focused on freezing of scaly carp sperm utilizing a practical and inexpensive protocol for aquaculture. Semen was diluted with Kurokura’s extender composing 3.6 g/l NaCl, 10 g/l KCl, 0.22 g/l CaCl2, 0.08 g/l MgCl2 and 0.2 g/l NaHCO3. The extender contained three different cryoprotectants (DMSO, DMA and egg yolk) at ratios of 5, 10 and 15 %. Semen was placed into 0.25-ml straws and exposed to liquid nitrogen vapor (?120 °C) using an insulated box with an adjustable tray for 10 min and then plunged into liquid nitrogen (?196 °C) tank. The thawing process was performed in a water bath at 40 °C for 10 s. The results indicated that type of cryoprotectants and their concentrations are rather effective in scaly carp sperm cryopreservation on post-thaw sperm quality, while they are very important in order to obtain high fertilization rates. The highest fertilization rate was determined as 96.4 ± 0.15 % with 15 % egg yolk, while the highest hatching rate was determined as 99.3 ± 0.80 with 15 % DMA. In conclusion, the applied cryopreservation method for scaly carp sperm is suitable to fertilize high amounts of eggs. 相似文献
Study aims to investigate the effects of vermicomposts containing oil processing wastes, dairy manure, municipal open market wastes and straw on the growth, nutrient concentrations and nutrient uptakes of corn plant. For this, there different mixtures were prepared. Vermicomposts were applied with the rates of 0, 5000, 10000, and 20000 kg ha?1 to 2 kg soil containing pots. Study was conducted in growth chamber for 2 months. Vermicompost applications increased plant growth, some plant nutrient concentrations and uptake. Also, vermicomposts showed the variation on parameters depending on their mixtures. Results showed that nutrients taken by the plant increased with the vermicompost until 10000 kg ha?1 dose. Most of the nutrient concentrations such as phosphorus, potassium, calcium, magnesium, iron, and manganese (P, K, Ca, Mg, Fe, and Mn) were not increased in plant tissues, whereas uptake of them by the plant showed a significant increase. In addition, residual soil nutrients increased with the increase in vermicompost levels. 相似文献
Meat quality characteristics of Bafra ram lambs slaughtered at different weights were investigated. A total of 24 lambs fattened
intensively was slaughtered at four slaughter weights of 30, 35, 40, and 45 kg. Water-holding capacity, cooking loss, tenderness,
color, as well as protein content did not vary significantly among the slaughter weight groups, although the 30-kg slaughter
weight lambs displayed the greatest postmortem pH fall in musculus longissimus dorsi (P < 0.05). As slaughter weight increased, intramuscular fat of musculus longissimus dorsi showed an increasing nutritive value
(P < 0.05), total unsaturated fatty acids/saturated fatty acids ratio (P < 0.05), and n6/n3 ratio (P < 0.05). However, atherogenic index and thrombogenic index values decreased with increasing slaughter weight, although this
effect was not significant. The effect of slaughter weight on total cholesterol was not pronounced. 相似文献
1.?The objective was to evaluate the effects of brooding temperature on intestinal development, oxidative organ damage, and performance of chicks acclimated to high temperature during incubation. The effects of acclimation and brooding temperatures on slaughter weights of broilers under heat stress were also investigated.
2.?Eggs were incubated at either 37?8°C (INCCont) or heat-acclimated at 39?5°C for 6 h daily from d 10 to d 18 of incubation (INCH). Brooding temperatures at floor level were set at 32, 33?5 and 35°C (Bt32, Bt33?5, Bt35, respectively) for the first 5 d. The temperature was reduced gradually to 30°C from d 6 to d 10. From 21 to 42 d, broilers from INCCont Bt32 and INCH Bt32 and Bt35 were divided into two groups; half from each group was exposed to daily cyclic higher ambient temperatures, while the other half was reared at control temperature.
3.?INCH chicks had lower jejunum, but greater liver and residual yolk sac weights than INCCont chicks on the day of hatching. Although INCH chicks from Bt33?5 and Bt35 had lighter body weights than Bt32 on d 5, no significant differences were observed in the body weight of broilers among treatments at 10 and 21 d.
4.?Similar jejunum protein, alkaline phosphatase, maltase, glutathione, and malondialdehyde contents of chicks from INCCont and INCH suggested that heat acclimation during incubation has no effect on jejunum enzyme activity or oxidative status of chicks.
5.?Taking into account INCH Bt35 chicks having lower T3 levels on d 5, lower heterophil/lymphocyte (H/L) ratios and similar weights at 42 d under heat stress compared with control broilers, the results suggested that although higher brooding temperatures had no effect on body weights of INCH chicks during the brooding period, those broilers may able to cope better with heat stress. 相似文献
Kosovo, one of the countries in the Balkan Peninsula, has a long tradition in sheep farming, and sheep breeds share triple purpose breed characteristics: milk, meat and wool. Bardhoka sheep, also with triple productive profile, is an important sheep breed because of its economic value with its milk production. In this study, 24 mandibles of adult Bardhoka sheep (12 male and 12 female) aged between 2 and 5 were used. The sheep were acquired from slaughterhouse around Kosovo, and the mandibles were selected without any deformities from healthy sheep. After cleaning the mandibles, a total of 12 morphometric measurements were taken from each sample using digital calliper. The difference between female and male was statistically significant (p < .05) for measurement 11 (height of mandible level of alveolar edge of 3rd molar tooth). The mean value of measurement 11 in male individuals was 42.26 ± 3.96, and it had a higher value than in female individuals (39.37 ± 2.57). In the literature, knowledge related to mandible morphometry of Bardhoka sheep was insufficient. The aim of this study was to determine mean values from osteometric measurements of Bardhoka sheep mandible and obtain references with the values acquired. 相似文献
