Abstract Seasonality and lack of organic substrates suitable for the production of citrus rootstocks are the main problems in seedling production, coupled with the fact that these materials have alkaline pH. The objective of this study was to evaluate the effect of substrates composed of Pinus sp. needles and a commercial alkaline substrate at different concentrations on the growth and development of Poncirus trifoliata (L.) Raf rootstock. The development of ‘Trifoliata’ was assessed in different mixtures (v:v) of a commercial substrate (Vida®) based on eucalyptus bark and Pinus sp. needles (0, 25, 50, 75 and 100 %) with two particle sizes (3.5 and 8.0 mm). A randomized block experimental design with 10 treatments of seven plants each and four replications was used. During rootstock development, we monitored: the pH, electrical conductivity and stability of the substrates; the dry mass of the aerial part, roots and stem; and vegetative growth and development. Increasing the proportion of needles in the mixture with alkaline substrate reduced the pH, electrical conductivity and density. Treatments with 3.5 mm needles showed greater stability than those with 8 mm ones. The use of 25 % needles provided better results compared to 0 % (alkaline substrate only); however, the need for a specific fertilization and irrigation system for each treatment was detected, as each new substrate has its own physical and chemical characteristics.","PeriodicalId":38261,"journal":{"name":"Revista Chapingo, Serie Horticultura","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48697947","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}

The objective of this research was to evaluate the effect of preharvest spraying of ethephon, calcium prohexadione, iodine and sodium selenite on some physicochemical quality parameters in greenhouse-grown saladette tomato fruits. The experimental design was completely randomized and the evaluated variables were color, weight, equatorial and polar diameter, roundness index, firmness, total soluble solids (TSS), titratable acidity (TA) and lycopene concentration. Individual application of ethephon (1.6 mL∙L) and iodine (5 mL∙L) significantly increased fruit weight (133.71 g) and firmness (3.26 N), with respect to the control (80.36 g and 0.95 N). Fruits that showed the highest TA (0.34 % citric acid) were those sprayed with 125 mg∙L of sodium selenite. On the other hand, the equatorial and polar diameter, TSS and lycopene concentrations, brightness, hue and roundness index did not differ statistically among treatments. Preharvest foliar application of ethephon, iodine and sodium selenite could be considered as an agronomic management alternative in greenhouse tomato production systems.","PeriodicalId":38261,"journal":{"name":"Revista Chapingo, Serie Horticultura","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70582607","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}

The three races that gave rise te modern avocado cultivars-Antillean (West Indian), Guatemalan and Mexican-accordingly are adapted te quite distinct environmental conditions. The apparent Mexican-Guatemalan hybrids that originated around Atlixco in Puebla State, Mexico, exemplified by 'Fuerte', showed remarkable adaptation when moved to the Mediterranean-type subtropical microcIimates cornmon in southern California, permitting a commercial industry to develop and later be transferred to other parts of the world with similar climates, such as South Africa, Israel and Chile. Selection from the material originally brought from Mexico and Central America permitted California to develop commercial cultivars exemplified by 'Hass', 'Fuerte' and 'Reed', among others, that lead the world in the area planted. Guatemalan cultivars are adapted te elevated situations in Central America, yielding well under cool conditions and forming an important dietary staple. The Antillean race, 'which probably originated aIong the Pacific coast in Central America, yields well in lowland tropical situations and warm subtropical areas such as southern Florida. Planting Guatemalan and Antillean avocados side-by-side in Florida ea¡'ly in this century produced a new group of hybrid cultivars with quality superior to that of most Antillean cultivars, adaptation te sea level locations, and an extended range of season of maturity that permitted Florida te market fruit into the autumn and winter, well past the season of pure Antillean cultivars. The best of these hybrids, 'Booth 7', 'Booth 8', 'Lula', 'Choquette' and a few others have been exported te warm locations about the tropical world for commercial planting. Thus, selection of avocado germplasm imported from Mexico and Central America into California and Florida produced a group of cultivars that are of significant commercial importance in the world.","PeriodicalId":38261,"journal":{"name":"Revista Chapingo, Serie Horticultura","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"1999-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70581200","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}
