The present study was carried out in order to reveal the effects of exogen melatonin (50MT: 50 µM - 100 MT: 100 µM) treatment on the growth rate characteristic and bioactive compound content variations of three spinach cultivars (Acosta-ACO; Anlani-ANL, and Matador-MTR, respectively) grown under cold conditions. While MTR was the richest variety in terms of chlorophyll a, chlorophyll b, total chlorophyll, and carotenoid content, ANL was the richest variety in terms of Chl a to Chl b ratio, and xanthophyll content. Ascorbic acid and protein concentration were stimulated by MT in all three variants, but ANL had the highest value. While the proline content of cultivars decreased with only 50 MT in ACO when compared to the control, GB content decreased in MT doses. RWC increased with MT in ANL, whereas it caused to a decrease in RWC of 100 MT in ACO and 50 MT in MTR. MDA concentration was at a lower level and decreased only in ACO with 50 MT when compared to the control, while the H 2 O 2 concentration was higher at MT doses in all three species. MT treatment stimulated SOD activity in ACO and ANL and increased POD activity in all three variants. Considering the growth characteristics such as root/stem length, leaf characteristics, and biomass, exogenous MT doses had positive effects on all three cultivars. These findings suggest that foliar MT treatment can attenuate cold damage by enhancing the enzymatic and non-enzymatic antioxidant capacity of spinach seedlings, as well as the growth rate.","PeriodicalId":7975,"journal":{"name":"Applied Ecology and Environmental Research","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67126948","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Coral reefs in Southeast Asia are becoming progressively degraded due to the natural and anthropogenic disturbances which lead to poor water quality threatening the reefs’ health. Coral disease is one of the threats to the coral reefs worldwide but research on coral disease in Southeast Asia is relatively scarce especially on bacterial community associated with the disease. The destructive coral black band disease (BBD) can be found widely in the southern region of the South China Sea, Malaysia. This study aims to compare the microbial communities of healthy and BBD-infected coral tissue from two different coral species Montipora turtlensis and Acropora spicifera collected at the Shark Point of Pulau Redang, Terengganu. The bacterial isolated from corals nubbins were examined by combining culture-dependent method and bacterial sequencing of 16S rDNA. A total of 18 bacteria isolates were identified from both species of coral tissue samples prior to sub-culturing colonies samples. The sequences detected were derived from a wide taxonomic range, including representatives of Actinobacteria, Furmicutes and Proteobacteria phyla. Bacteria belonging to the phyla Proteobacteria were further divided into alpha and gammaproteobacteria. Most of the bacteria identified can be found on healthy and BBD-affected coral tissue samples; however, there are few bacteria which can be only found on BBD-affected tissue of respective coral species such as Lelliottia sp., Salnicola salarius and Microbacterium petrolearium for M. turtlensis while Pseudomonas stutzeri and Erythrobacter sp. for A. spicifera.","PeriodicalId":7975,"journal":{"name":"Applied Ecology and Environmental Research","volume":"51 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67128335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Royle and Polygonatum verticillatum (L.) All. are important medicinal herbs of the ‘Ashtavarga group’ of medicinal plants and belongs to the family Asparagaceae. The populations of these species are declining in the natural habitat due to various anthropogenic factors; hence, it is important to know existing status of the species for devising conservation and management plan. Keeping that in view, study was conducted in different geographical locations of Himachal Pradesh during June-September 2019. Nine sites falling in four districts for P. cirrhifolium and 23 sites falling in five districts for P. verticillatum were selected to assess their population status by quadrat method using random sampling and following vertical belt transects approach. The population of the P. cirrhifolium was recorded maximum at Kulang site (Dm -2 = 7.27 ± 10.91, F = 23.33%), and lowest at Shakoli (Dm -2 = 0.43 ± 0.82, F = 13.33%). The value of abundance ranged from 2.89 (Batseri) to 14.25 (Nichar). IVI was found maximum at Kulang (61.72) and the lowest at Shakoli (9.16) site. Whereas population of P. verticillatum was recorded maximum at Hatu (Dm -2 = 8.33 ± 3.43, F = 60%), and lowest at Paneta Khud (Dm -2 = 0.73 ± 1.24, F = 20.0%). The value of abundance ranged from 3.62 (Kothi) to 13.89 (Hatu). Frequency was found maximum at Baghi (66.67%) and lowest at Paneta Khud (20.0%). The Shannon diversity index and IVI was found maximum at Jamathu (0.36 and 91.02) and lowest at Paneta Khad (0.18 and 19.81). Both species were distributed in small populations with low density and frequency and were found geographically isolated.","PeriodicalId":7975,"journal":{"name":"Applied Ecology and Environmental Research","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67132053","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To study the influences of the physical and chemical properties of different seedling cultivation substrates on the quality and yield of machine-transplanted seedlings in China, seeds of the rice (Oryza sativa L.) variety Yangjing 805 were sown in topsoil (TS), commercial seedling substrate (CS), straw (ST), rice husk (RH) and mushroom residue (MR). Changes in the seedling quality, nutrient content, and grain yield were analyzed. The results showed that the morphological indices and nitrogen metabolism-related enzymatic activities of seedlings treated with TS, CS, and MR were significantly higher than of those treated with ST and RH. The reduction in total N, alkali-hydrolyzed N, and available P was lower under TS and MR than under any other treatment. The highest rice yield was recorded for the MR treatment, with a 28.93% higher yield compared with the ST treatment. Among the seedling morphological indices, stem thickness (R 2 = 0.9604) and shoot dry weight (R 2 = 0.8835) showed the highest correlations with yield, while root length (R 2 = 0.8919) and root surface area (R 2 = 0.9125) were the root indices with maximum values. The variables that showed the closest relationship with seedling quality were bulk density, conductivity, and pH of the growing medium.","PeriodicalId":7975,"journal":{"name":"Applied Ecology and Environmental Research","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136306433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Grape seed is a product that is released as waste during the processing of grapes. It is described as ecological damage. Recently, its availability in animal nutrition has been discussed due to the high content of tannins and phenolics contained in it. It is thought that grape seeds can reduce the adverse conditions that occur in the rumen with the high amount of antioxidant properties they contain. This study investigated the effects of grape seed on acidosis and gas production in the rumen under in vitro conditions. The nutritional composition of the present product, in vitro gas production (GP), and the differentiation of gases formed in the rumen (NH 3 , CH 4, and CO 2 ) under acidosis conditions were determined. The pH values of the rumen fluid were measured at the 0, 24, 48, and 96th hours of incubation. Grape seed did not have an effect on rumen pH under normal conditions. However, in the rumen, due to its high amount of antioxidant properties during periods of acidosis, it showed a positive effect on the linear improvement of intra-rumen pH. It was concluded that further studies should be conducted, in which the mechanism of action of grape seed on animals with acidosis was studied.","PeriodicalId":7975,"journal":{"name":"Applied Ecology and Environmental Research","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135007723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study was carried out to examine the effects of Urtica dioica extract on goat cryopreserved semen quality. The ejaculates of Markhoz goats (n = 12) were collected by an electro-ejaculator. The semen was diluted and supplemented with different concentration of aqueous or hydroalcoholic Urtica dioica extract of aerial or root parts as follows: aerial-aqueous (AA1 5μg/ml , AA2 15μg/ml and AA3 45μg/ml ); aerial-ethanolic (AE1 5μg/ml , AE2 15μg/ml and AE3 45μg/ml ); root aqueous (RA1 5μg/ml , RA2 15μg/ml and RA3 45μg/ml ); root-ethanolic (RE1 5μg/ml , RE 215μg/ml and RE3 45μg/ml ) and control (CCC 0mg/ml ) without additives. After thawing, sperm samples were subjected to viability, acrosome integrity, plasma membrane integrity, motility, sperm chromatin dispersion (SCD) and concentration of malondialdehyde (MDA) assays. Addition of AA1 5μg/ml to the extender significantly (P < 0.05) improved progressive motility, viability, plasma membrane integrity, acrosome integrity, and DNA integrity of the semen samples. Sperm viability and plasma membrane integrity in aqueous extract (both aerial & root parts)-supplemented extenders were relatively higher, as compared to the control. Moreover, a significant decrease in MDA concentration was detected in semen supplemented with Urtica dioica extract treatments. In conclusion, the results indicate that 5μg/ml of aqueous extract of Urtica dioica aerial part improved sperm quality and could be recommended as an additive to the extender for cryopreservation. This study shows a novel approach in goat semen cryopreservation due to the remarkable influence of Urtica dioica on post-thawed sperm parameters.","PeriodicalId":7975,"journal":{"name":"Applied Ecology and Environmental Research","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136307214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
