Tofanelli Francine Lorena Cuquel Jessica Welinski de Oliveira D’angelo José Gilberto Sousa Medeiros <p><strong>The postharvest phase is an important step in the fruit production chain. Fig is an especially perishable fruit, which has encouraged researchers to study the effects of various substances on the postharvest life of this commodity. The objective of the present work was to evaluate the effects of calcium chloride (CaCl<sub>2</sub>) and 1-methylcyclopropene (1-MCP) on the postharvest quality of the ‘Roxo-de-Valinhos’ fig cultivar. This study aimed to verify the effects of applying a 4% solution of CaCl<sub>2</sub> and a 1% solution of 1-MCP to figs and evaluating at four different storage times (0, 2, 4, and 6 days). The results showed that a 4% solution of CaCl<sub>2</sub> promoted better firmness, and when CaCl<sub>2</sub> at 4% was applied in combination with 1-MCP at 10 μg l-1, the maturation index increased. In contrast, the 1-MCP treatment alone did not improve the postharvest quality of ‘Roxo-de-Valinhos’ ripe fig. We conclude that application of 4% solution of CaCl<sub>2</sub> and 1-MPC at 10 µg l<sup>-</sup>¹ promote firmness and increase maturation index of 'Roxo-de-Valinos' figs.</strong></p> 2022-02-25T00:00:00+00:00 Copyright (c) 2022 MAURO TOFANELLI, Francine Lorena Cuquel, Jessica Welinski de Oliveira D’angelo, José Gilberto Sousa Medeiros Diallel analysis of selected yield-contributing traits in Okra [Abelmoschus esculentus (L.) Moench] 2022-07-01T17:41:03+00:00 Chriatian Okechukwu Anyaoha O. A. Oyetunde O.O. Oguntolu <p><strong>Information on gene action controlling quantitative traits is important for effective selection. A five-parent diallel cross, which generated 10 F1 hybrids of okra (<em>Abelmoscus esculentus</em>) were evaluated during the early and late planting seasons of 2019 in Ibadan, Nigeria. Data obtained were subjected to diallel analysis and genotype by yield-trait (GYT) biplot analysis to estimate combining ability effects and identify stable hybrids for measured traits respectively. Genotype mean squares were significant (p≤0.01) for all most measured traits. Furthermore, General Combining Ability (GCA) and Specific Combining Ability (SCA) mean squares were significant (p≤0.05/0.01) for most measured traits, indicating the influence of additive and non-additive gene actions in expression of these traits. Preponderance of non-additive gene effects shows the high influence of the environment on most of the considered traits in this study. Iwo Nla had the most desirable GCA estimates of -0.98 and 1.14, for days to 50% flowering (DTF), number of fruits per plant (NoF) respectively while IK11 had the most desirable GCA values for mature-fruit width (0.21) and 1000-seed weight (5.71). SCA estimates were most desirable for NH47-4 × LD88, NH47-4 × Iwo Nla, with values of -4.21 and 4.32 for DTF and NoF respectively. Hybrids NH47-4 × Iwo Nla and IK11 × Clemson associated with higher NoF x trait might be useful for improvement of number of fruits per plant in this population.</strong></p> 2022-03-10T00:00:00+00:00 Copyright (c) 2022 Chriatian Okechukwu Anyaoha, O.

Shishe-kab) to ethanol, sodium bicarbonate dips and modified atmosphere packaging 2022-07-01T17:41:10+00:00 Maryam Dorostkar Farid Moradinezhad <p><strong>Pomegranate fruit is very popular due to its high commercial importance and health benefits. This experiment aimed to evaluate the sensory quality, color, and biochemical properties (TSS, TA, TSS/TA, anthocyanin content and total antioxidant capacity) of pomegranate fruit under post-harvest treatments, included ethanol (EtOH), sodium bicarbonate (SBC), and different packaging. Experimental treatments included: 10% (v/v) EtOH, 1% (w/v) SBC, and the type of packaging (passive-MAP and vacuum). Fruit were then stored at 5±1°C and 90% relative humidity for ten weeks. The peel and aril color evaluations indicate that EtOH treatment and vacuum packaging (VP) improved the quality of pomegranate color by increasing<em> a*</em> and decreasing <em>L*</em>. These treatments made the skin color and aril color lighter and redder in pomegranate. In addition, the treatments reduced decay and maintained total soluble solids (TSS), and titratable acidity (TA). Interestingly, EtOH treatment improved fruit nutritional quality as it increased total antioxidant capacity and anthocyanin content by 20% and 50%, respectively, compared to the control. The sensory analysis indicated that treated fruit with EtOH and VP scored higher in taste, color, texture, and appearance, and showed the best acceptability from the panelists’ viewpoint. In conclusion, EtOH and VP significantly improved pomegranate fruit quality during cold storage since preserved sensorial quality and bioactive compounds and reduced decay.</strong></p> 2022-03-10T00:00:00+00:00 Copyright (c) 2022 Maryam Dorostkar, Farid Moradinezhad Effect of chemical and biological fertilizers on the morphology and yield of safflower and soybean under monoculture and intercropping 2022-07-01T17:40:55+00:00 Yaghoub Raei Roghaye Ghahremani Saeid Ghassemi Jalil Shafagh-Kolvanagh <p><strong>Intercropping and biofertilizers application are the most important agricultural methods for moving towards minimizing the risks of agricultural production and increasing production efficiency. Consequently, this experiment was conducted at one year and in 2019. A factorial set of treatments was arranged within randomized complete block design (RCBD) with three replications to investigate the effect of different planting ratios with safflower and soybean (sole cropping, 30:100 soybean to safflower ratio, 60:100 soybean to safflower ratio and 90:100 soybean to safflower ratio) and nutrient levels (100% urea fertilizer, 100% biofertilizer and the combined application of urea and biofertilizer) on growth and yield of these crops. The results of this study indicated that intercropping patterns had the highest plant height, number of grains per plant, biological and grain yields. In addition, the means of the number of heads per plant and the number of grains per head in safflower and the weight of 1000 grains in soybean were increased as intercrops were grown. Maximum of grain number per plant in safflower, leaf number per plan in soybean and biological and grain yields in both crops were attained in urea + biofertilizer. In all of intercropping patterns the values of LER (land equivalent ratio), RVT (relative value total) and RCC (relative crowding coefficient) was more than one, indicating an advantage from intercropping over sole crops.</strong></p> 2022-03-31T00:00:00+00:00 Copyright (c) 2022 Yaghoub Raei, Roghaye Ghahremani, Saeid Ghassemi, Jalil Shafagh-Kolvanagh Effect of different packaging materials on shelf life and postharvest quality of tomato (Lycopersicum esculentum var. Srijana) 2022-07-01T17:40:48+00:00 Sarita Poudel Pratik Aryal Manoj Basnet <p><strong>Tomatoes, being highly perishable, experience extreme post-harvest losses due to improper packaging materials. Experimentation was done to investigate the effect of different packaging materials on shelf life and quality traits of tomato var. Srijana at the horticulture laboratory of the Institute of Agriculture and Animal Science, Lamjung Campus under a completely randomized design. Seven treatments viz. no packaging (control), unperforated low-density polyethylene (LDPE) bag, perforated (4 holes of 2 mm) LDPE bag, unperforated high-density polyethylene (HDPE) bag, perforated HDPE bag, unperforated non-woven fabric bag, and perforated non-woven fabric bag with 3 replications were used. Tomatoes were evaluated for weight loss, color development, total soluble solids, titratable acidity, pH, and shelf life. Among the treatments, the lowest percentage of weight loss (0.66%) was observed on tomatoes packed in an unperforated HDPE bag, however, it had a higher fungus attack. No packaging group showed rapid shriveling of fruits with the highest percentage of weight loss (14.70%). Although packaging in a non-woven fabric bag was better than control, it showed a higher percentage of weight loss than plastic packaging due to its high permeability to gases and water vapor. The TSS and pH values were found to be higher and TA to be lower in no packaging compared to other packagings. The longest shelf life of tomatoes was observed in perforated LDPE (24 days), followed by HDPE (23 days) whereas the lowest was observed in control (16 days). Overall, the perforated plastic packaging was found best among all treatments with no significant variation among perforated HDPE and perforated LDPE for maintaining qualities of tomatoes and longer shelf life.</strong></p> 2022-04-04T00:00:00+00:00 Copyright (c) 2022 Sarita Poudel, Pratik Aryal, Manoj Basnet Maintaining physicochemical and sensory properties of guava var. Getas Merah using alginate and Cyclea barbata leaveas powder as edible coating 2022-07-01T17:40:33+00:00 Nafi Ananda Utama Iin Anggi Pranata Putrika Citta Pramesi <p><strong>Indonesia is one of the major countries which contributes the world’s guava production. Guava var. Getas Merah is commonly found in Indonesia. Guava has a short shelf-life as it rapidly goes under postharvest ripening. This leads to a faster deterioration of physicochemical and sensorial properties of guava. A generally used method to extends shelf-life is by edible coating. In this study, a combination of alginate and <em>Cyclea barbata</em> leaves powder (CBLP) was investigated as a potential edible coating. The analysis of firmness, total soluble solids, total reducing sugar, total titratable acidity and organoleptic tests were conducted to evaluate the quality of guava fruits stored for 20 d at 14°C. A split plot design study was used and four different treatments with different CBLP concentrations were applied. The samples treated with 2% alginate and 0.8% CBLP showed the lowest total dissolved solids, total reducing sugar, and total titratable acidity. Moreover, the samples were reported with the highest score on color, taste, and texture parameters. The firmness test showed that samples treated with 2% alginate and 0.2% CBLP had the lowest firmness loss and highest score for aroma. In summary longer quality retention of guava fruits was found after the addition of CBLP in alginate-based edible coating.</strong></p> 2022-04-26T00:00:00+00:00 Copyright (c) 2022 Nafi Ananda Utama, Iin Anggi Pranata, Putrika Citta Pramesi Salinity effects on growth, chlorophyll content, total phenols, and antioxidant activity in Salvia lavandulifolia Vahl. 2022-07-01T17:40:41+00:00 Hassan Bayat Fatemeh Shafie Basireh Shahraki <p><strong>Although the effect of salinity stress on some species of Salvia has been studied, so far no research has been done on <em>S. lavandulifolia</em> species. Therefore, a greenhouse pot experiment was carried out to investigate the impacts of salt stress on vegetative parameters, chlorophyll content, and antioxidants activity in <em>Salvia lavandulifolia</em> Vahl. Treatments included different irrigation water salinity levels (S0=1.3, S1=3.3, S2=5.3, S3=7.3, S4=9.3, S5=11.3, and S6=13.3 dS m<sup>-1</sup>) which were arranged in a completely randomized design. The results showed that salinity treatments significantly affected the plant growth attributes. The lowest plant height, leaf number, leaf length, and shoot dry weight was recorded in the S6 treated plants with 62%, 41%, 44%, and 82% decrease compared to the control, respectively. Treatment of <em>S. lavandulifolia</em> plants with the highest salinity level (S6) decreased the content of chlorophyll a, chlorophyll b, and total chlorophyll by 57%, 53%, and 54% compared to the control, respectively. Salt stress at all levels increased the total phenolic content, and the highest value was obtained in the S6 treated plants. Free radical scavenging capacity was significantly increased by all the levels of salinity stress, and the highest (85.14%) value was obtained in the S6 treated plants. In general, <em>S. lavandulifolia</em> can be classified as a species-sensitive plant.</strong></p> 2022-04-26T00:00:00+00:00 Copyright (c) 2022 Hassan Bayat, Fatemeh Shafie, Basireh Shahraki Observation of unexpected neo like-fruit development from Cakile maritima calli 2022-07-01T17:40:25+00:00 Delphine Arbelet-Bonnin Sylvie Cangémi Patrik Laurenti François Bouteau <p><strong><span lang="EN-US">Parthenocarpy, the ability of some plants to undergo fruit growth in absence of fertilization, is an important question of basic science and the subject of much interest due to its possible agricultural benefits.
