The so-called strategy I plant (e. g. Pea, Pisum sativum L.) which groups dicotyledons and monocots other than grasses, developed root membrane activities that contribute to the improvement of Fe availability. Among the functions considered to be a critical phase in iron absorption is rhizosphere acidification by H-ATPase and Fe(III) reduced by Fe(III) chelate reducctase (FeCR). In order to experimentally investigate the importance of root FeCR in Fe nutrition, its relationship with rhizosphere acidification and the genotypic differences in response to iron deficiency in pea (Pisum sativum L.), a glasshouse experiment was conducted hydroponically on four genotypes Merveille de Kelvedon (MK); Lincoln (Lin); Douce de Provence (DP) and Alexandra (Alex). Plants of each genotype were distributed into two plots, the first one received full nutrient solution (+ Fe), the second one received nutrient solution devoid of iron (- Fe). Plant growth, Fe distribution, SPAD index and root acidification and ferric chelate reductase activities were evaluated. Fe deficiency decreased plant growth and SPAD index along with the significant increase of H-ATPase and FeCR activities. Some genotypic differences were observed as follows; Alex showed high tolerance to Fe deprivation as compared to other genotypes. Important H-ATPase and FeCR activities, high Fe use efficiency and adequate membrane efficiency are the main reasons for this tolerance. These physiological parameters could be used as tools of tolerance for further breeding programs","PeriodicalId":11075,"journal":{"name":"Day 1 Mon, June 28, 2021","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84580097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Developing drought-adapted wheat cultivars is paramount to increase wheat productivity under variable rainfall conditions. Understanding the genetic variability and trait association is key to the development of improved wheat cultivars. The objective of this study was to determine the extent of the genetic parameters and associations of yield and yield components of bread wheat genotypes, in order to design appropriate breeding strategies for yield improvement in wheat. One hundred and twenty genotypes were evaluated at five test sites in the 2018/19 cropping season using a 10 x 12 alpha lattice design with two replications. Different sowing dates were used to impose contrasting drought stress levels based on the onset of the main seasonal rains at each site. Data were recorded on agronomic traits such as days to heading (DH), days to maturity (DM), plant height (PH), spike length (SL), spikelet per spike (SS), kernel per spike (KS), 1000 kernel weight (TKW) and grain yield (GY). There was significant (p<0.01) genetic variation for all agronomic traits studied under both drought-stressed and non-stressed conditions. The highest estimates for genetic variance were obtained for DH (54.0%), followed by SL (38.3%). The high heritability estimated for DH (94.4%), SL (90.2%) and SS (85.2%), coupled with a high rate of genetic advance, suggest that direct selection for these traits would be effective under drought-stressed conditions. GY exhibited low genetic advance (9%) and heritability (41.5%) estimates, which were concomitant with its polygenic and complex inheritance pattern. Correlation and path analyses revealed that TKW was the most important contributing trait for improving grain yield under drought-stressed conditions","PeriodicalId":11075,"journal":{"name":"Day 1 Mon, June 28, 2021","volume":"37 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87713314","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research was carried out to study the effect of frequency application of consortium saline-tolerant bacteria isolates with different soil ameliorants on growth and yield of tomato grown saline lands. Research was conducted using split plot design with three replications. Soil ameliorants (Cow manure and gypsum) were the main plot while sub-plots were frequency applications of consortium bacterial isolates (without bacterial, once, twice, three and four times). In this study, bacteria consortium was SN13 (Streptomyces sp.) + SN22 (Bacillus sp.) and SN23 (Corynebacterium sp.) which isolated from the soil of saline-prone regions of Lamongan, in coastal East Java Indonesia. Results showed that gypsum and cow manure as soil ameliorant did not give significant effect on yield and nutrient uptake of tomato while application of saline-tolerant bacteria was able to improve yield and nutrient uptake of tomato. However, the four times application of saline-tolerant bacteria significantly improved plant height (23.36 %), leaves area (96,49 %), total chlorophyll content (11.86 %), dry weight of plant (103.59 %), fresh weight of fruit (85.51 %), N uptake (135.22 %), P uptake (132.99 %), K uptake (141.68 %) and declined Na uptake (16.28 %), compared to without bacteria application.

Six samples of Staphylococcus spp. from Veterinary Students’ nasal swabs were collected for antimicrobial susceptibility tests. The antibacterial activities of the aqueous extracts of ginger rhizome and leaves were evaluated with broth microdilution, and then synergism of the rhizome extract with the antimicrobials was verified to calculate the fractional inhibitory concentration index (FICI). All the Staphylococcus spp. samples showed resistance to ampicillin and penicillin, 66.67% to erythromycin, and 33.33% to tetracycline. The MIC90% of each extract was estimated to be 235 mg/mL and 13.27 mg/mL for the leaf and rhizome, respectively. With the aqueous leaf extract, none of the samples presented MBC within the studied concentration range. On the other hand, the MBC obtained by the aqueous rhizome extract was 7.81 mg/mL for 50% of the samples.

Treatments consisted of two different maize-soybean plant stand (40,000 and 60,000 plants ha-1) and five nitrogen fertilization levels (0, 50, 100, 150, and 200 kg ha-1). As a result, soybean biomass yield increased at the lower maize plant stand, although, maize and total (maize + soybean) biomass yield were higher at the greater maize plant stand. Thus, individual maize plants and total dry matter yield increased as nitrogen levels were increased. However, there was no effect of the studied factors on the silage crude protein yield per area, indicating a great potential of soybean to offset biomass yield reduction trough silage quality improvement. Moreover, since there was no difference on total silage crude protein yield per hectare, it is suggested that the adoption of maize-soybean intercrop with lower maize plant stand (40 thousand maize plants ha-1) and with lower nitrogen values is a more environmentally friendly approach to increase farmland sustainability while decreasing environmental and productivity costs.
