Genetic, biochemical and physiological parameters can be changed by applying seaweed extract-based products. However, there is scarce information about the influence of seaweed extract on yarrow performance (Achillea millefolium L.), which is widely used in the folk medicine. Therefore, this study aimed to evaluate the effects of Ascophyllum nodosum extract on plant development (leaf and root biomass, and leaf area), physiological indexes (leaf weight ratio, and root: leaf ratio), secondary metabolite (phenolic compounds) content and antioxidant activity of yarrow. The experiment was carried out in a completely randomized design with 4 treatments (seaweed extract concentrations 0, 3, 6 and 9 mL L-1) and 10 replications. The higher concentration of seaweed extract caused higher total dry weight of plants (from 17.8 to 19%), especially due to increases in the root biomass (up to 28.5%). Only plants that received the highest concentration of seaweed-based product presented increments in the number of leaves when compared to the control plants (18.3 %). Furthermore, the use of A. nodosum extract 9 mL L-1 provided increases in the antioxidant activity and content of phenolic compounds in leaves (up to 30.44%). In conclusion, application of A. nodosum is a potential tool strategy to improve the quality of raw material from yarrow plants, since it increased the phenolic compound content and antioxidant activity in leaves, which are the plant organs commonly used in folk medicine.
应用海藻提取物产品可以改变遗传、生化和生理参数。然而，在民间医药中应用广泛的蓍草(Achillea millefolium L.)中，关于海藻提取物对蓍草性能影响的研究却很少。因此，本研究旨在评价野参提取物对蓍草植株发育(叶、根生物量、叶面积)、生理指标(叶重比、根、叶比)、次生代谢物(酚类化合物)含量和抗氧化活性的影响。试验采用完全随机设计，设4个处理(海藻提取物浓度分别为0、3、6和9 mL L-1)， 10个重复。海藻提取物浓度越高，植株总干重越高(从17.8%增加到19%)，特别是根系生物量增加(高达28.5%)。与对照植物相比，只有接受最高浓度海藻基产品的植物叶片数量增加(18.3%)。此外，使用9 mL L-1的木参提取物可提高叶片的抗氧化活性和酚类化合物含量(达30.44%)。综上所述，在野蓍草中添加野蓍草可提高野蓍草叶片中酚类化合物的含量和抗氧化活性，是提高野蓍草原料质量的潜在工具策略。

Searches for soil management systems that aim at maintaining soil quality are fundamental, along with sustainable agricultural and farming management. Thus, the aim of the present research was to assess soil parameters such as porous system, soil resistance to penetration, aggregate stability, relative soil density and the S index of an Oxisol under the conventional and no-till sowing management systems of corn production. They soils of the experimental areas were classified as a typical Oxisol with medium texture (LVd1) and typical Oxisol of clayey texture (LVd2). The experimental design was completely randomized split plot, with six replications. The plots (60 m2) consisted of six soil management systems (1 - SD1LVd1 = after one year no-till sowing; 2 - SD8LVd1 = after 8 years no-till sowing; 3 - SD10LVd1 = after 10 years no-till sowing; 4 - CCLVd1 = conventional sowing; 5 - SD12LVd2 = after 12 years no-till sowing; 6 - CCLVd2 = conventional sowing) and the subplots consisted of three soil layers (0-0.10, 0.10-0.20 and 0.20-0.30 m deep). The results showed that in three analyzed layers, the no-till sowing on medium texture Oxisol had higher densities. Treatments of medium texture Oxisol showed higher values of maximum soil density. This occurred because the clay content influenced a larger quantity of surface charges and specific surface area which decreased the susceptibility to soil compacting. The 12-year-old no-till sowing yielded the lowest corn productivity (5.9 Mg ha-1), probably due to the formation of compact layers, mainly near the soil surface.

Fertilizer application can enhance the nutritional value of plants, such effects being influenced by the presence of arbuscular mycorrhizal fungi (AMF). Nutrients × AMF interactions are well-known for variety of elements but very little has been addressed on biofortification of selenium (Se) in plants grown in tropical soils. The purpose of this study was to evaluate the effect of Se application and AMF inoculation on growth and micronutrient contents on soybean plants as forage grass. The experiments were conducted in a completely randomized factorial design with five Se doses (0.0, 0.5, 1.0, 2.0 and 3.0 mg kg-1 for soybean plants, and 0.0, 0.5, 1.0, 3.0 and 6.0 mg kg-1 for forage plants), with and without AMF inoculation in three replicates. The results showed that soil Se had only slight effect on soybean growth but it caused a two-fold increase on grain yield. However, the growth of forage grass was enhanced by Se application when AMF was present. The AMF inoculation reduced benefit for soybean growth and yield but marked positive effect on forage grass at high doses of Se. Selenium contents in both plants were increased by its application in soil, being such effect proportional to soil applied doses. Selenium application and AMF inoculation had marked effects on micronutrients contents in both soybean plants and forage grass and they may contribute to Se and micronutrient biofortification.

Seed quality is extremely important for the crop production system, and storage conditions are important to preserve this quality. The objective this study was to evaluate the physiological quality of yellow passion fruit seeds with different water contents placed in a cold chamber room (4°C) and in a natural laboratory environment (25 ± 2°C) for a period of eight months (240 days). Passion fruit seeds were harvested in orchards of the southern region of Espírito Santo, with water content adjusted to 10%; 14%; 18% and 22%, and placed in a cold chamber room and a natural laboratory environment. Germination, germination speed index, shoot and root length, fresh and dry mass of normal seedlings were evaluated. The experimental design was completely randomized, with two environments (cold chamber room and natural laboratory environment) and with a plot experimental arrangement subdivided according to time, with four replicates of 25 seeds within each environment. Yellow passion fruit seeds placed in a cold chamber room and natural environment with 14% of water content presented a higher physiological quality during eight months of storage. Yellow passion fruit seeds placed in a cold chamber room and natural environment presented maximum germination and vigour with 60 days of storage. Yellow passion fruit seeds exhibit orthodox behaviour, and should be stored at 14% of water content, in a cold chamber room and natural environment, without loss of viability and physiological quality over eight months, presenting maximum germination and vigour after 60 days storage, without the presence of pathogens.

Papaya (Carica papaya L.) is one of the main horticultural crops of many tropical and subtropical regions. The fruit is sold either as a fresh product or processed into drinks, jams, candies, dried and crystallized fruit, while the enzyme papain is used for medicinal purposes. Papaya fruits have high vitamins A and C contents, as well as are good sources of calcium. Brazil is one of the most important producers and exporters of papaya in the world; in 2016 c.a., 1,424,650 tons of papaya was produced in 30,372 hectares of the territory. Optimum light absorption and utilization by the canopy are important factors for maximizing papaya crop growth and productivity. Thus, knowing how papaya responds to light is important to develop management strategies to optimize fruit yield and quality. This short review aims to present the current research knowledge related to the effects of light intensity on the photosynthetic processes and growth of papaya. We demonstrate that photosynthetically active radiation (PAR) greatly affects the physiology of papaya. Understanding the interaction between light and physiological processes is extremely important for a sustainable profitable production under either greenhouse or field conditions. By using improved light science-based management, growers may optimize photosynthetic carbon assimilation and increase papaya yield and fruit quality

Soursop is a fruit of great socioeconomic importance for the northeastern region of Brazil. However, the quantitative and qualitative limitation of the water resources of this region has reduced its production. The objective of this study was to evaluate the growth of ‘Morada Nova’ soursop plants irrigated with saline water and subjected to exogenous application of hydrogen peroxide through seed immersion and foliar spray. The study was conducted in plastic pots adapted as lysimeters, using a eutrophic Regolithic Neosol with sandy loam texture under greenhouse conditions. Treatments were distributed in randomized blocks, in a 4 x 4 factorial arrangement, corresponding to four levels of irrigation water electrical conductivity – ECw (0.7; 1.7; 2.7 and 3.7 dS m-1) and four concentrations of hydrogen peroxide – H2O2 (0, 25, 50 and 75 µM), with three replicates and one plant per plot. Foliar applications of H2O2 began 15 days after transplanting (DAT) and were carried out every 15 days at 17:00 h, after the sunset, by manually spraying the H2O2 solutions with a sprayer in such a way to completely wet the leaves (spraying the abaxial and adaxial faces). Treatment effects were evaluated based on plant height (PH), stem diameter (SD), number of leaves (NL) and leaf area (LA) at 60 and 90 DAT, and dry phytomass of leaves (LDP), stem (SDP), roots (RDP) and total (TDP) and leaf succulence (LS) at 90 DAT. Irrigation using water with estimated ECw of 1.55 dS m-1 caused acceptable mean reduction of 10% in soursop growth. Increasing concentrations of hydrogen peroxide did not attenuate the effects of salinity on plant height and leaf area during the vegetative stage. Hydrogen peroxide concentration of 20 µM led to higher leaf succulence in soursop plants.

Green manures can replace or supplement mineral fertilization and add organic matter to the soils, ensuring greater sustainability to fruit growing in semiarid regions. Biological fixation, transfer and balance of nitrogen were determined on an irrigated yellow passion fruit orchard (Passiflora edulis Sims) intercropped separately with three cover crops: sunn hemp, Crotalaria juncea (L.); pigeon pea, Cajanus cajan (L.) Mill; and jack bean, Canavalia ensiformis (L.) DC. In a fourth treatment, legumes were not planted, but spontaneous vegetation was left to grow freely. The legumes were croped for 90 days in three lines (0.5 m apart) inside the passion fruit plant lines (2.5 m apart). Fixation and transfers were determined by the 15N natural abundance technique, using sunflower as a reference plant. The three planted legumes nodulated abundantly and fixed nitrogen in high proportions (between 50 and 90% of their N), forming symbiosis with bacteria naturally established in the soil. Jack bean produced more biomass than sunn hemp and pigeon pea, and as much as the spontaneous plants, of which 23% were legumes. The amounts of fixed N (150, 43, 30 and 29 kg ha-1) were determined mainly by the biomass of legumes. More than 40% of the N of passion fruit plants came from the biological nitrogen fixation of the intercropped jack bean, which provided an amount of N higher than that exported in the fruits, generating a positive balance of more than 100 kg ha-1. Therefore, it is recommended to intercrop jack bean in irrigated passion fruit orchards.
绿色肥料可以替代或补充矿物肥料，并向土壤中添加有机物，确保半干旱地区水果种植的可持续性。以西番莲(Passiflora edulis Sims)为研究对象，研究了西番莲(Passiflora edulis Sims)在灌溉条件下与三种覆盖作物(sunhemp, Crotalaria juncea, L.)间作的生物固结、氮转移和氮平衡;鹰嘴豆，鹰嘴豆(L.)磨粉机;和豆荚，Canavalia ensiformis (L.)直流。在第四种处理中，不种植豆科植物，但让自然植被自由生长。在百香果株系(相距2.5 m)内分3行(间隔0.5 m)种植豆科植物90 d。以向日葵为对照植物，采用15N自然丰度技术测定固定和转移。种植的三种豆科植物结瘤丰富，固氮比例高(占其氮的50%至90%)，与土壤中自然形成的细菌形成共生关系。杰克豆比太阳大麻和鸽子豆产生更多的生物量，和自发植物一样多，其中23%是豆类。固氮量(150、43、30和29 kg hm -1)主要由豆科植物生物量决定。西番莲植株40%以上的氮来自间作豆角的生物固氮，提供的氮量高于果实输出的氮量，正平衡量大于100 kg ha-1。因此，建议在西番莲灌溉园间作豆角。

Biological fixation, transfer and balance of nitrogen were determined on an irrigated yellow passion fruit orchard (Passiflora edulis Sims) intercropped separately with three cover crops: sunn hemp, Crotalaria juncea (L.); pigeon pea, Cajanus cajan (L.) Mill; and jack bean, Canavalia ensiformis (L.) DC. In a fourth treatment, legumes were not planted, but spontaneous vegetation was left to grow freely. The legumes were croped for 90 days in three lines (0.5 m apart) inside the passion fruit plant lines (2.5 m apart). Fixation and transfers were determined by the 15N natural abundance technique, using sunflower as a reference plant. The three planted legumes nodulated abundantly and fixed nitrogen in high proportions (between 50 and 90% of their N), forming symbiosis with bacteria naturally established in the soil. Jack bean produced more biomass than sunn hemp and pigeon pea, and as much as the spontaneous plants, of which 23% were legumes. The amounts of fixed N (150, 43, 30 and 29 kg ha-1) were determined mainly by the biomass of legumes. More than 40% of the N of passion fruit plants came from the biological nitrogen fixation of the intercropped jack bean, which provided an amount of N higher than that exported in the fruits, generating a positive balance of more than 100 kg ha-1.

Neutral nanoparticles (NPs) of iron, zinc, copper or their compositions were introduced into nutrient Murashige-Skoog (MS) medium instead of traditional metal salts with/without chitosan supplements to obtain healthy and crop productive plants. Metal NPs concentrations were: Fe NPs (0.06, 0.3, 3.0); Zn NPs (0.016, 0.08, 0.4); Cu NPs (0.004, 0.0008, 0.00016) (mg L-1). Pepper (Capsicum annuum) cultivar LJ-King was grown on modified media in aseptic conditions. After 45 days, root and stem length, root activity, green mass gain and chlorophyll content in leaves were measured. Pepper plants grown on media with metal NPs showed increased root length and activity (for Fe, Zn, Cu NPs and their composition) and chlorophyll content in leaves (for NPs Fe and Cu). However, addition of Chitosan modified the effects. Monitoring of pepper grown on MS with NPs composition (Fe: Zn: Cu as 3.0:1.0:0.004 mg L-1) with electron microscope demonstrated no NPs accumulation in roots, sprouts and leaves.
