Cladode Pruning Affects Yield and Fruit Quality of ‘Roja Lisa’ Cactus Pear [Opuntia ficus-indica (L.) Mill.]: A Preliminary Study

Aims: This study assessed the initial effect of experimental pruning (EP) or grower’s pruning (GP) of cactus pear fruiting cladodes on fruit yield (FY), fruit size distribution (FSD), and fruit quality (FQ) at harvest and after storage. Study Design: Treatments were arranged in a completely randomized design with eight or ten replicates, with a single plant as replicate, for EP or GP, respectively. Place and Duration of Study: The experiment was set up in a drip-irrigated commercial orchard of ‘Roja Lisa’ cactus pear [O. ficus-indica (L.) Mill.] plants located at Santa Fe, Jerez, Zacatecas, México, from February to August 2006. Methodology: The EP considered two agronomic practices: 1) exposing the center of each plant while eliminating unproductive cladodes and those shading other cladodes and 2) concentrating fruiting cladodes in the outer part of the plants. The GP randomly eliminated some cladodes from the central part and around the plants only. Treatments were arranged in a completely randomized design with eight or ten replicates, with a single plant as replicate, for EP or GP, respectively. The response variables were: FY, FSD, and FQ at harvest and after storage. The FQ attributes were: mean fruit mass (MFM), flesh firmness (FF), total soluble solids concentration, pulp and peel mass, dry matter concentration, and fruit water loss (FWL) during storage. Results: EP increased MFM by 42% over GP and produced 15% more marketable fruit (fruit equatorial diameter from 5.0 to 7.0 cm), but FY was reduced by 39%. The FF was higher in EP fruit than GP fruit after storage. The other FQ attributes were similar in both pruning treatments, both at harvest and after three weeks at room temperature. The FWL was also similar under both pruning systems. More targeted pruning has the potential to increase the productivity of cactus pear orchards. Conclusion: Experimental pruning increased fruit size and the percentage of commercial fruit, but reduced both overall and commercial fruit yields. After three-week storage at room temperature, flesh firmness remained greater in EP fruit. Fruit water loss was not influenced by pruning treatments during the storage.

The use of natural products as coatings to preserve the fruit quality during storage is an important step to maintain food safety for consumer health. The use of microalgae in coatings, therefore, may be promising in the preservation of mango. The present work had the objective to evaluate the effect of coatings based on Chlorella sp. on the postharvest preservation of ‘Tommy Atkins’ mango during storage at room temperature (23 °C). We carried out a completely randomized design experiment consisting of 0%, 1%, 2%, 3% and 4% of Chlorella sp., using 10 fruits per treatment (n = 10). Analyzing the L*, a* and, b* indices, in the peel and the pulp of the mango fruit, we observed a delay in the ripening with the increase of the biofilm concentration. The firmness of the pulp and maintenance of the organic acids of the fruits were higher in the treatments with a large amount of Chlorella sp. The use of biofilm with Chlorella sp. at 2% preserved the quality of ‘Tommy Atkins’ mango until ten days of storage, at 23 °C and 42% RH.

A field trial was conducted during 2015 and 2016, to study the effect ofgrowth regulators on growth, flowering, yield and fruit quality of strawberry cv. Chandler. The experiment was laid out in completely randomized design with 16 treatments viz.CPPU at 1, 2 and 4 ppm, GA3 at 25, 50 and 75 ppm, Promalin at 2, 4 and 6 ppm, GA4+7 at 5, 10 and15 ppm, NAA at 10, 20 and 30 ppm and control (water spray) and each treatment was replicated thrice. The results revealed that the plants sprayed with 15 ppm GA4+7 two weeks before flowering significantly reported highest plant height (33.43 cm), leaf area (239.70 cm2), number of flowers (31.94), fruit set (87.45 %), number of fruits per plant (29.02), yield (540.01 g/plant), fruit length (53.63 mm) and fruit diameter (37.19 mm) and fruit weight (23.70 g) as compared to control. This treatment resulted in 196.36 % increase in yield and 56.22 %in fruit weight over control. Plants sprayed with 6 ppm promalin also showed significant improvement in vegetative growth, fruit size, yield and fruit quality, which resulted in 137.92 % increase in yield and 51.81 % increase in fruit weight over control. Hence, it is concluded that foliar spray of 15 ppm GA4+7 applied 2 weeks before flowering is beneficial in improving growth, yield and fruit quality of strawberry plants.

The objective of this study was to evaluate the viability of ‘jabuticaree açu’ [Plinia cauliflora (DC.) Berg] seeds according to water loss and packaging conservation conditions. Two experiments were carried out at UTFPR - Dois Vizinhos Campus, Parana State, Brazil. For the first experiment, the seeds were submitted to the hydro conditioning process by soaking in water during 24 hours with subsequently storage in a BOD chamber at 25°C for 0, 12, 24, 36, 48, 60, 72, 84 and 96 hours. This experiment was conducted in a completely randomized design with four replications of 50 seeds each. For the second experiment the seeds were separated into three lots: PET® bottles with lids, kraft® paper bags at room temperature and in cold storage (6°C±1°C). Each lot was stored during 0, 5, 10, 15, 20, 25, 30, 60, 90, 120 and 150 days. The experiment was carried out in a completely randomized design, in a 3x11 factorial (storage location x storage period), with four repetitions of 50 seeds each. Plinia cauliflora seeds present storage capacity of 96 hours at room temperature without loss of germination capacity, when previous hydro conditioning was carried out. Storage using Pet® bottles at room temperature for up to 25 days allows seeds viability.

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.

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.

And Storage

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.

Cactus pears face challenges due to global climate change, which is leading to in-depth research to monitor and increase their water activity. The objective of this study was to evaluate the use of the natural test hydrogel (TH) from Orbignya phalerata fibre as nutrients and water for growing cactus pear genotypes (“Baiana” and “Doce” [Nopalea cochenillifera], ‘Gigante’ [Opuntia fícus-indica], and “Mexican Elephant Ear” [Opuntia stricta]) compared to the use of commercial hydrogel (CH), which is based on polymers composed of polyacrylamide, and a treatment without the use of hydrogel (WH). A completely randomized design was used, in a factorial scheme (4 × 3), with four genotypes of cactus pear and three forms of hydration, with five replications. The number and area of cladode was greatest (p < 0.01) in plants with CH and TH irrigation-fertilization in the ‘Doce’ cactus genotype. The dry biomass of the cladode and root in the ‘Gigante’ cactus genotype was greatest (p < 0.01) in the treatments with CH and TH irrigation-fertilisation. The ‘Baiana’, ‘Doce’, and ‘Gigante’ cactus genotypes exhibited more (p < 0.01) dry matter content with the TH irrigation-fertilisation. The highest (p < 0.01) neutral detergent fibre content was observed in the ‘Baiana’ and ‘Doce’ cactus genotypes when irrigation occurred with WH treatment, and the highest acid detergent fibre content in the ‘Gigante’ genotype. The copolymerized natural fibre from the mesocarp of Orbignya phalerata (babassu fruit) induced a better growth and chemical composition of cactus pear genotypes than the hydrogel based on polymers composed of polyacrylamide.

Abstract The objective of this study is to evaluate the vegetative and productive behavior of kiwifruit trees cv. ‘Elmwood’ submitted to different intensities of pruning, in “Serra Gaúcha” region. Treatments consisted in maintaining different bud load levels in each cane of 10, 15 and 20 buds cane-1. The experiment, carried out during the 2016/2017 vegetative season had a completely randomized design with nine repetitions per treatment. Bud fertility, vegetative, productive and fruit quality features were evaluated. The percentage of mixed buds was higher next to the cane apex in three different treatments, while in the base of each cane ocurred the highest percentage of non sprouting buds. The decrease in the number of buds per cane induced larger leaves and increased leaf dry matter. Longitudinal and transversal diameter of fruits and fruit mass were inversely proportional to the number of buds per cane. Pruning of ‘Elmwood’ kiwifruit tree with different number of buds did not influence the index of real bud fertility, but affected directly leaf and shoot size. Pruning maintaining canes with 10 buds favors the increase of fruit weight and did not reduce productivity.

An experiment using cv. Taiwan was 786 laid out in factorial completely randomized design with thirty treatments and three replications was, carried out at Laboratory of Horticulture Section, College of Agriculture, Dhule (M.S.) during 2017. The experiment comprised of three factors viz. two maturity stages (25% mature and 50% mature), dipping them in aqueous solutions of spermine (1.0 mM and 2.0 mM) and calcium lactate (1% and 2%) for 5 minutes and drying for 30 minutes at room temperature, three packaging materials (newspaper, shrink film and polyethylene bags) were used. Results indicated a significant impact of interaction among maturity stages, spermine and calcium lactate and packaging material on all parameters included in the study. When considered interaction, twenty five percent mature fruits dipped in (2.0 mM) spermine with shrink packaging had the minimum physiological loss in weight. This treatment also recorded the maximum peel to pulp ratio, fruit firmness. The maximum shelf life of 16 days without sacrificing organoleptic quality by manipulating the time of harvesting, packaging and application of spermine.
