Salt stress is one of the main limitations to Triticum aestivum productivity all around the world. An experiment was conducted to assess the effect of Trichoderma harzianum seed coating on germination and seedling development of wheat under salt stress (60 and 120 mM NaCl). The seeds of six wheat cultivars, namely Shafaq-06, Punjab-11, Millet, Seher, Pirsabik, and Aari were seed coated with Trichoderma (taken from NARC Pakistan) at the rate of 2 x 107 CFU using PelGel for 24 h. After air-drying at room temperature for 12 h, the coated seeds were sown in small pots. Experimentation was laid out in a completely randomized design with three replications. The data for various biochemical attributes were collected after 30 d of germination to test the seed and seedling vigor, respectively. Trichoderma harzianum seed coating reduced the amount of hydrogen peroxide, catalase, Malondialdehyde, and increased protein content, Ascorbate Peroidase, and total phenolics under salt stress advocating that its use is effective in the cultivation of crops in saline areas because it inhibits oxidative damage by triggering various phenolic compounds and scavenging proteins.

AbstractEthylene plays a crucial role throughout the life cycle of plants under optimal and stressful environments. The present study reports the involvement of exogenously sourced ethylene (as ethephon; 2-chloroethyl phosphonic acid) in the protection of the photosynthetic activity from glucose (Glu) sensitivity through its influence on the antioxidant system for adaptation of wheat (Triticum aestivum L.) plants under salt stress. Ten-day-old plants were subjected to control and 100 mM NaCl and treated with 200 µl L−1 ethephon on foliage at 20 days after seed sowing individually or in combination with 6% Glu. Plants receiving ethylene exhibited higher growth and photosynthesis through reduced Glu sensitivity in the presence of salt stress. Moreover, ethylene-induced reduced glutathione (GSH) production resulted in increased psbA and psbB expression to protect PSII activity and photosynthesis under salt stress. The use of buthionine sulfoximine (BSO), GSH biosynthesis inhibitor, substantiated the involvement of ethylene-induced GSH in the reversal of Glu-mediated photosynthetic repression in salt-stressed plants. It was suggested that ethylene increased the utilization of Glu under salt stress through its influence on photosynthetic potential and sink strength and reduced the Glu-mediated repression of photosynthesis.

The increased rate of sugarcane harvest without previous burn has provided a very favorable environment to the froghopper Mahanarva fimbriolata (Stal, 1854), with high moisture and low temperature variation. Few works have studied the response of sugarcane to this pest, so little is known about resistant cultivars. Plant phenolics are widely studied compounds because of their known antiherbivore effect. This research aims to determine if the attack of M. fimbriolata nymphs stimulates the accumulation of total phenolics in sugarcane. The experiment was carried out in greenhouse and arranged in completely randomized design, in a 3 X 2 X 4 factorial with three replications. Second instar nymphs of M. fimbriolata were infested at the following rates: control, 2-4 and 4-8 nymphs per pot (first-second infestations, respectively). Pots were covered with nylon net and monitored daily to isolate the effect of leaf sucking adults. Leaf and root samples were collected and kept frozen in liquid nitrogen until analyses. Infested plants showed higher levels of phenolics in both root and leaf tissues. In roots, the cultivar SP80-1816 accumulated more phenolic compounds in response to the infestation of M. fimbriolata. On the other hand, higher levels were found in leaves and roots of control plants of SP86-42, which might be an indication of a non-preference mechanism. The increase of total phenolics in sugarcane infested with root-sucking froghopper nymphs does not seem to be useful to detect the resistance to this pest.

This research was aimed to determine the quality properties, the microstructure of chicken sausage and Thiobarbituric acid (TBA) values with locally Indonesia red beetroot powder. The main ingredients of chicken sausage-making in this research were broiler chicken, filler, binder, beetroot powder, and spices. Red beetroot powder function as a filler was substituted tapioca starch in chicken sausage batter in three different levels. The combination of red beetroot powder with level 0, 1.0, 2.0 and 3.0% of total batter and shelf life at room temperature for 0, 1, 2 and 3 days. Each treatment consisted of five replications. The variables observed using quality properties (moisture, ash, fat, protein, crude fiber and calorie), microstructure and peroxide value of chicken sausage. The data of quality properties and peroxide value were analyzed by using one-way analysis (ANOVA) of Completely Randomized Design. The differences between means were analyzed by Duncan's New Multiple Ranges Test. The data of microstructure was analyzed by descriptive analyses. The moisture, protein, fat and ash contents for chicken sausages were significantly different (p<0.05). The chicken sausage with 2% substitution of beet powder produced chicken sausages with a high protein content of 14.77±0.02% while a low-fat content is 0.42±0.01%. Thiobarbituric acid (TBA) values of chicken sausages increased throughout the three days of room temperature storage (38°C). Chicken sausage formulated with red beetroot powder showed a significantly lower TBA value compared to the samples without red beetroot powder (p<0.05). In conclusion, a higher level of beetroot powder will improve the quality of chicken sausage and also the microstructure. The best level of beetroot powder addition was 2.0%. The addition of beetroot powder able to maintain fresh sausage conditions up to 2 days of storage at room temperature.

The gain body weight and Spoilage of meat broiler which giving jaloh extract to combine with chromiumABSTRACT. A study was conducted on broiler chickens under heat stress to evaluate the effect of combined jaloh (Salix tetrasperma Roxb) extract with chromium mineral in the body weight, value of feed ratio conversion, and time to meat to become decomposed. Twenty four of 20-day old Cobb female broiler chickens were randomly assigned and divided to 4 treatment groups. Completely randomized design was used in this study. The treatments were as follows: 1) chickens given no heat stress and jaloh extract nor chromium (tCp); 2) chickens under heat stress without given jaloh extract nor chromium (Cp); 3) chickens under heat stress and given jaloh extract in 1.000 mg/lt drinking water (Cp+Ej); and 4) chickens under heat stress, given jaloh extract in 1.000 mg/lt drinking water, and chromium in 1.000 ug/lt drinking water (Cp+Ej+Cr). Heat stress given was 33 ± 1oC of cage temperature during 4 hours per day within 15 days. Jaloh extract and chromium treatments in drinking water were given at 2 hour before cage temperature reaching 33 ± 1oC and were stopped being given after 1 hour, when cage temperature back to room temperature. On the 16th day of the study chickens were measured before slaughtered. Samples obtained were chicken meat that taken from breast part (musculus pectoralis). The result suggested that either giving jaloh extract per se at the dose of 1.000 mg/lt in drinking water or combine it with chromium that given two hours before cage temperature reaching 33 ± 1oC, can prevent chickens from decreasing their body weight, decreasing value of feed ratio convertion, and extending time to meat to become decomposed.

Garlic (Allium sativum L.) is an agricultural commodity which is widely consumed by the community. The obstacle experienced in cultivation is that a relatively long dormancy period of about 6-7 months. The dormancy of garlic seeds occurs because the embryo has not yet been fully formed, and the growth hormone and inhibitory hormone are not balanced. The methods used to break dormancy and accelerate germination are by using corona incandescent plasma radiation and storage temperature. The research utilized factorial Completely Randomized Design (CRD), consisting of six treatments with five replications. The first factor was the corona incandescent plasma radiation carried out on the garlic seeds ‘Lumbu Kuning’ variety with time duration of 0, 15, and 30 minutes. The second factor was storage temperature comprising of room temperature and cold temperature of 7oC stored for 30 days. Viability parameters observed are germination percentage dan the length of sprouts. The data were analyzed by using ANOVA followed by the DMRT test at the 95% confidence level. The results showed that corona incandescent plasma radiation influenced the germination percentage using plasma radiation for 15- 30 minutes.
