ABSTRACT The artificial flowering induction in mango tree is the most important crop management in mango orchards and requires greater attention from growers. The management involves three steps: stoppage of plant growth, branch maturation and flowering induction with nitrates. The first stage starts with the application of paclobutrazol to the soil. However, problems with the use of excessive concentrations are common and lead to the accumulation of residues in the soil. In addition, the use of paclobutrazol is not allowed in organic agriculture. Therefore, this review article aimed to compile information about the updates and efforts to solve these problems in conventional mango crops, as well as identify alternatives for its organic management. In conventional orchards, the application of fulvic acids in association with paclobutrazol, as an alternative to the single use of paclobutrazol, was identified as a way to improve the absorption of the product by plants and, consequently, reduce the concentrations and residues in the soil. Researches involving pruning, girdling, fertilization and irrigation should be developed as an alternative to the use of paclobutrazol for the organic crop system of mango cultivars in tropical and subtropical regions.

ABSTRACT The 'Ubá' mango tree cultivar is very important for the juice industry in the "Zona da Mata" region of the Minas Gerais State, in Brazil, but problems such as uneven flowering and low yield have discouraged producers. This study aimed at evaluating the effect of paclobutrazol, combined with branch tip pruning, on the flowering induction and quality of 'Ubá' mango tree fruits. Treatments were distributed in a 5 x 2 + 1 factorial arrangement, consisting of five paclobutrazol doses (0 g, 0.50 g, 1.00 g, 1.50 g and 2.0 g per linear meter of canopy), with and without branch tip pruning, in a randomized blocks design, with four replicates. The flowering percentage, number of panicles per branch, total flowers per panicle, male/hermaphrodite flowers ratio, number of fruits per branch and fruit quality were evaluated. Plants treated with tip pruning showed a higher flowering percentage. There was an increase in the flowering percentage in response to the paclobutrazol dose, reaching a maximum level at the dose of 1.62 g per linear meter of canopy. Plants submitted to branch tip pruning had a higher number of panicles per branch. There was an increase in the male/hermaphrodite flowers ratio with increasing paclobutrazol doses. Branch tip pruning increased the number of fruits per branch. There were no differences in fruit quality in response to the paclobutrazol application. It was concluded that the paclobutrazol application at the dose of 1.62 g per linear meter of canopy, combined with branch tip pruning, increases the flowering of the 'Ubá' mango tree and does not change the fruit quality.

Cell-to-cell communication in plants is mediated by plasmodesmata (PD) whose permeability is tightly regulated during plant growth and development. The actin cytoskeleton has been implicated in regulating the permeability of PD, but the underlying mechanism remains largely unknown. Recent characterization of PD-localized formin proteins has shed light on the role and mechanism of action of actin in regulating PD-mediated intercellular trafficking. In this mini-review article, we will describe the progress in this area.

Lipid-derived plant hormone jasmonates are implicated in plant growth, reproductive performance, senescence, secondary metabolite productions, and defense against both necrotrophic pathogens and feeding insects. A major jasmonate is (+)-7-iso-jasmonoyl-l-isoleucine (JA-Ile), which is perceived by the unique COI1-JAZ coreceptor system. Recent advances in plant chemical biology have greatly informed the bioscience of jasmonate, including the development of chemical tools such as the antagonist COR-MO; the agonist NOPh; and newly developed jasmonates, including JA-Ile-macrolactone and 12-OH-JA-Ile. This review article summarizes the current status of plant chemical biology as it pertains to jasmonates, and offers some perspectives for the future.

It is becoming increasingly evident from work carried out by various groups of research workers throughout the world (Thomas and Hill, 1949; Blackman and Wilson, 195 I ; Donald, 195 1, 1956; Black, 1955; Watson, 1956) that the amount of light energy available to herbage and crop plants is a major controlling factor in plant growth. In a recent review article Black ( 1957) has stated, "It is clear from the evidence herein reviewed that the growth of pasture species, as of other plants, is markedly dependent on the light environment, and that the quantity of light energy available rather than the intensity appears to be the important factor. Apparently the greater the quantity of light energy available up to the highest values recorded in the field, the better the growth."

Abstract This book contains 5 chapters that presents a simple, straightforward discussion of the principles and processes involved in the production of grain yield by agronomic crops, and how these processes underlie and influence management decisions. The focus is on grain crops, principally maize and soybean, although the general principles apply equally well to cereals, grain legumes and oil crops. Management decisions define all cropping systems - what (crop species, variety), where (climate), when (planting date), and how (row spacing and population density) are the fundamental choices. Knowledge of the fundamental processes responsible for plant growth and the accumulation of yield simplifies the decision-making process and leads to improved management decisions, higher grain yields, and cropping systems that are efficient, resilient and sustainable. The contents include basic plant growth processes (e.g. photosynthesis, respiration, evapotranspiration); growth and production of yield; crop management (seed quality, variety selection, planting date, row spacing); and crop production in the future (climate change, GMOs, precision agriculture and new crops). This books is intended for researchers in crop science, agronomy and plant science, and crop production practitioners. This book will enable readers to make better, more informed management decisions; decisions that will help maintain a well-fed world in the future.

Fulvic acids (FAs) improve the structure and fertility of soils with varying textures and also play a crucial role in increasing crop production. The pot experiment was carried out using wheat grown on three soils with a silty clay, sandy loam, and clay loam texture, respectively. The soils were treated with FAs derived from plant and mineral materials. Plant-derived solid (PSFA), mineral-derived liquid (NLFA), and plant-derived liquid (PLFA) were applied at a rate of 2.5, 5, and 5 g kg−1 and control applied at 0 g kg−1. The results showed that in treated soils, the heavy fraction C was higher by 10%–60%, and the light fraction C increased by 30%–60%. Similarly, the available N content significantly increased in treated soils by 30%–70% and the available K content increased by 20%–45%, while P content significantly increased by 80%–90% in Aridisols and Vertisols and decreased by 60%–70% in Mollisols. In contrast, for P, the organic–inorganic compounds were greater in Aridisols and Vertisols and lower in Mollisols. However, organic–inorganic composites decreased in Vertisols relative to the other two soils. Further results showed that PSFA and NLFA accelerated the plant growth parameters in Mollisols and Aridisols, respectively. Our study demonstrates that the application of PSFA and NLFA had a positive effect on the physical and chemical properties and plant growth characteristics of Mollisol and Vertisol soils. Moreover, the application of solid-state FA yields better results in Mollisols. However, liquid FA increases the nutrient availability and the effects on the chemical, biological, and physical properties of Aridisol and Vertisol soils.
