Their populations have been affected by habitat destruction, illegal extraction, and uncontrolled tourism in the region that steps on the seedlings; therefore, knowing its reproductive biology is necessary for its conservation. Our main questions were: What is the floral morphology and anatomy like? What type of sexual and mating system do M. lasiacantha present? Do the seeds produced by the crosses germinate, how and in what percentage? Sixty individuals from a population of 120 plants were studied at Sierra of Juárez, Juárez Chihuahua from January to August 2021. The study of the floral morpho-anatomy was carried out. Four treatments were applied: natural selfing, forced selfing, geitonogamy and forced outcrossing plus a control. Pollinated flowers, fruits, number of seeds and germination percentage were recorded. Flowers have naked pericarp, funnel-type nectary, nectarostomata, closed style and collateral vascular bundles. The anatomical characteristics of M. lasiacantha agree with those reported for other species of Mammillaria. The flowers of M. lasiacantha present herkogamy, with an obligate outcrossing system. The seeds produced from the outcrossing and control group germinated in 32 and 76%, respectively. The herkogamy and strict outcrossing system of M. lasiacantha should be confirmed in other populations. The seeds are positive photoblastic, without dormancy, but the study of the seed bank and seedling survival in the field would be pertinent. The ex-situ conservation of M. lasiacantha in the site will be feasible, since species high percentage of germination may contribute to produce plants for restoration programs.","PeriodicalId":54361,"journal":{"name":"Journal of the Professional Association for Cactus Development","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140697221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To lessen this negative occurrence, moisture availability provides better performance for the species, such as using hydrogel instead of irrigation. The objective of this study was to evaluate the effect of using hydrogel polymers on the production of cactus pear (Opuntia stricta cv. Mexican Elephant Ear). Three treatments with six replications were used, totalling 18 experimental units. The treatments were, (1) Conventional fertilization using fertilizer in granulated format; (2) Foliar fertilization with polymer using a dilution dose of 6 grams of polymer L-1 of water associated with the fertilizer in liquid form through the foliar route; (3) Foliar fertilization without polymer using only foliar fertilization in the same formulation as the treatment with polymer. There was no effect of fertilization strategy on plant height, cladode length, cladode width, cladode thickness, cladode area, and biomass. There was an effect of the fertilization strategy on dry matter, in which higher estimates were measured for conventional fertilization and foliar fertilization without polymer. On the other hand, foliar fertilization with polymer promoted increases of 13% in mineral matter and 42% in crude protein in relation to conventional fertilization. The fertilization strategy did not change the other chemical attributes of cactus pear. The use of the hydrogel did not influence the morphometric development of the Mexican Elephant Ear cultivar but promoted increments in the chemical composition.","PeriodicalId":54361,"journal":{"name":"Journal of the Professional Association for Cactus Development","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140435480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study explored the influence of an alginate and mucilage-based edible coating on some physical attributes, cold storage, and consumer acceptance of avocado halves coated at the ready-to-eat stage. Two lots of avocado halves were formed. One was treated with an edible coating formulated from alginate and mucilage; the other was uncoated. Uncoated and coated avocado halves were cold-stored at 4 ± 1 °C and 95% relative humidity for 12 d. The fruit mass loss (FML), fresh firmness (FF), and some color parameters were measured every other day. The experiment was conducted in a completely random design with three replicates at each sampling date. On the sixth day, a sensory study was performed with 30 untrained panelists who were frequent avocado eaters. The coated avocado halves were brighter, redder, and yellower during the experimental period than uncoated avocado halves. A significant color differences (?E*) were found between coated and uncoated avocado halves. At the end of the experiment, the coated samples had the lowest FML and FF and the greatest consumer acceptance. Therefore, the edible coating presented here is a feasible technology for minimally-processed avocado halves and for high-latitude markets, where this fruit is scarce.","PeriodicalId":54361,"journal":{"name":"Journal of the Professional Association for Cactus Development","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2023-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138994124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, the physical and ecophysiological traits of Opuntia streptacantha seeds were evaluated to determine whether they are affected by sites. The seeds from eight sites of O. streptacantha from six Mexican states were studied, Sain Alto, Villa de Guadalupe, Villa González Ortega (Zacatecas), Zaragoza (San Luis Potosí), Lagos de Moreno (Jalisco), San Luis de La Paz (Guanajuato), Cardonal (Hidalgo) and Santiago Tepetitlán (Estado de México); being Lagos de Moreno and Santiago Tepetitlán the less dry sites and Villa González Ortega and Cardonal the drier ones. The longest seeds were from Zaragoza (3.81 mm), Villa González Ortega (3.72 mm) and Villa Guadalupe (3.70 mm); the widest and thickest seeds were from San Luis de La Paz (3.44 and 2.16 mm, respectively). The highest volumetric weight was found in seeds from Villa Guadalupe (9.92 kg hL-1), Lagos de Moreno (9.90 kg hL-1) and Santiago Tepetitlán (9.67 kg hL-1). The site San Luis de La Paz (1.31 g) had the highest weight of 1000 seeds and Cardonal (8874 seeds) the highest number of seeds per kilogram.

The seeds from the western region of the country (Lagos de Moreno), where the species is less abundant and the environment is moister, showed the highest germination (26%). The seed hardness was negatively correlated with seed germination, with soft seeds having the highest germination. No correlation between seed weight and germination was found. The seed traits are related to environmental factors that influence the seed quality.

In many of them, their populations within their range of distribution, are subject to three forms of management, including wild, in situ, and cultivated, each of one exposed to different types of damage, biological or physical. This study attempted to characterize the types of damage affecting pitayas (Stenocereus pruinosus and S. stellatus) in central and southern Mexico, and to analyze the relationship between some types of damage under different forms of management, and its effect on reproductive success. The two species were sampled in three populations with different forms of management. The branches (167-180) were selected and measured the amount of damage, characterized the types of damage, and a percentage of the total damage together with the number of fruits that were produced throughout their annual fruiting season were estimated. A x2 test was used to determine the variations in the characterized damage, and the effects of the damage on fruit production in populations with different forms of management was assessed using linear regressions. The eight different types of damage were listed, its frequency, and the effect of damage on fruit production varies in populations. Depending on human management, populations managed demonstrate acceptance of some types of damage by pitaya farmers: bird nests and external black scar, which do not affect the production of fruits; and reduction of others, branch rot and ant herbivory, the latter of which does affect the production of fruits. The fisheye disease, anthropogenic, gray scab and sooty mold and branch rot damage should be addressed in plant health activities in all populations, and the exchange of knowledge with pitaya farmers should be developed to propose measures to attend to these damages. This will support the sustainable use of the species.","PeriodicalId":54361,"journal":{"name":"Journal of the Professional Association for Cactus Development","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139198642","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The factors corresponded to five forms of moistening for corn grain silage, 0, 5, 10, 20, and 40% of cactus pear mucilage (MA) associated or not with urea (U) in the level of 1.5% of DM. The lowest DM content was found in the silage moistened with 40% of cactus pear mucilage, and the greatest CP content was found in the same treatment but when urea was added. Lower contents of propionic and butyric acids were observed in the silages moistened with 5 and 10% of cactus pear without and with the addition of urea. Dry matter recovery was higher in the treatments with water and 10% of cactus pear. The use of urea affected the LAB population only at 15 d of silo opening, providing a bigger population (6.58 logs CFU g-1) when compared to silages without urea (6.27 logs CFU g-1). The lower concentrations of propionic and butyric acids observed in the silage moistened with 5 and 10% of cactus pear mucilage, regardless of the addition of urea. However, it is recommended to use 10% of cactus pear mucilage without the addition of urea, as it provides better indicators of good-quality silage.","PeriodicalId":54361,"journal":{"name":"Journal of the Professional Association for Cactus Development","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135679165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to evaluate the lethal toxicity of malathion, lambda-cyhalothrin, spirotetramat, and potassium salts on D. opuntiae in laboratory and greenhouse assays. In the laboratory, using a potter tower, lethal concentrations (LC50 and LC90) were determined on adult females. Under greenhouse conditions, on O. ficus-indica infested plants, the LC90 of those three conventional insecticides were evaluated, as well as the LC50 of potassium salts; mortality was evaluated 48 and 144 h after application in laboratory and greenhouse assays, respectively. D. opuntiae was susceptible to all insecticides; malathion was the most toxic product, LC50 120.4 mg L-1, lambda-cyhalothrin (159.8 mg L-1) and spirotetramat (756.3 mg L-1) followed. Using potassium salts, 8,970.1 mg L-1 were needed to achieve 50% mortality.

The objective was to evaluate the use of extracts of betalains from Stenocereus pruinosus fruits with different tones and low sugar content in the pigmentation of food matrices. Aqueous biphasic systems (ABS) based on 1-propanol and sodium citrate were applied in multiple stages to obtain fractions rich in betaxanthins and betacyanins. Subsequently, an ABS based on polyethylene glycol 4000 and sodium citrate was used to reduce the sugar content. The extracts were used to pigment milk and to evaluate the color stability during a storage of 39 d at 4 °C. Four fractions, Eyellow, Eorange, Epink, and Ered, were obtained with betacyanins concentration of 9.23, 22.37, 76.54, and 61.0 mg L-1 and betaxanthins concentration of 49.3, 77.5, 35.2, and 53.32 mg L-1, respectively. The hue angle of the pigmented milk with Eyellow, Eorange, Epink, and Ered was 81.9, 60.6, 9.6, and 13.0°, respectively, at the beginning. The color remained without apparent change during 24 d, which allowed extracts of betacyanins and betaxanthins to be qualified as adequate to provide reddish and yellow hue in milk beverages. Although the multistage operation was required, four fractions with different tones were obtained from only one sample, which constitutes an innovative feature.
