Abstract The jacaranda of Bahia (Dalbergia nigra (Vell.) Allemão ex Benth) is an endemic tree of a Brazilian neotropical biodiversity hotspot and is of great ecological and economic interest. Given the threat of extinction due to timber overexploitation and climate change, the present study aimed to analyze the physiological and biochemical quality of D. nigra seeds exposed to heat stress. The seeds were sown in a test tube containing woody plant culture medium, kept in a biochemical oxygen demand chamber at 45°C for 0, 24, 48, 72, and 96 hours, and then maintained in the same chamber at 25°C for 30 days. Physiological analyses of moisture, electrical conductivity, germination speed index, normal and abnormal seedlings, seedling length, root length, hypocotyl length, collar diameter, seedling and root dry mass, and Dickson quality index revealed a drop in germination and vigor with prolonged heat stress, dropping from 95% to 0% between 0 and 96 hours. This was accompanied by a reduction in the content of carbohydrates, lipids, and proteins. Therefore, the vigor and quality of seedlings is negatively influenced by exposure to heat stress at 45°C. Study Implications: Dalbergia nigra is a species of high economic interest due to its high-quality wood. In the face of climate change, it is necessary to understand the behavior of seeds under temperature above the ideal. The quality and vigor of seedlings produced in vitro at a temperature of 45°C are negatively affected with the increase in hours of heat stress. In addition, the contents of lipids, carbohydrates, and proteins present in the seed reserves show a sharp drop with heat stress. Ultimately, heat stress significantly affects seed biochemistry and subsequent seedling physiology.

Кориандр овощной, как и все зеленные культуры, относится к скоропортящейся продукции, которая быстро теряет свои товарные качества. Для продления срока хранения зелени кориандра необходим альтернативный способ хранения. В 2020–2021 годах проведены исследования по изучению влияния упаковочных материалов (в том числе пакетов Xtend израильской компании StePac, создающих модифицированную атмосферу), используемых в комплексе с абсорбером этилена (саше) на основе перманганата калия Save Fresh, на изменение органолептических и биохимических показателей качества кориандра овощного сорта Бородинский при различных условиях хранения. Свежие листья кориандра упаковывали в полиэтиленовые пакеты плотностью 15 и 35 мкм, размером 36×25 см и массой 300 г и в пакеты Xtend, размером 66×54 см и массой 800 г. Контролем служили образцы, уложенные в открытый полимерный ящик. Хранили продукцию в течение пяти суток при температуре 10–12 °С, 14 суток при температуре 4–6 °С и 21 сутки при температуре 1–3 °С в холодильной камере с контролируемыми условиями. Относительная влажность воздуха – 90±3%. Максимальный выход товарной продукции кориандра отмечен при использовании упаковки Xtend МА/МВ с абсорбером этилена Save Fresh: при хранении в течение 5 суток при температуре 10–12 °C – 95,7%, 14 суток при 4–6 °C – 94,3%, 21 суток при 1–3 °С – 91,7%. Максимальное сохранение витамина С в продукции зафиксировано в варианте с Xtend-упаковкой – 33,8 мг% при показателе 40,1 мг% сразу после срезки зелени. Использование Xtend-упаковки израильской фирмы StePac, создающей модифицированную атмосферу/модифицированную влажность вместе с абсорбером этилена на основе перманганата калия Save Fresh, позволяет снизить потери и обеспечить сохранение качества зелени кориандра овощного сорта Бородинский в процессе транспортировки, хранения и реализации. Cilantro, like all green crops, refers to perishable products that quickly lose their marketable qualities. To extend the shelf life of cilantro greens, an alternative storage method is needed. In 2020–2021, studies were conducted to study the influence of packaging materials (including Xtend packages of the Israeli company StePac, which create a modified atmosphere) used in combination with an ethylene absorber (sachet) based on potassium permanganate Save Fresh, on the change in organoleptic and biochemical quality indicators of cilantro of the vegetable variety Borodinsky under various storage conditions. Fresh cilantro leaves were packed in plastic bags with a density of 15 and 35 microns, a size of 36×25 cm and a weight of 300 g and the Xtend packages, measuring 66×54 cm and weighing 800 g. The samples placed in an open polymer box served as a control. The products were stored for five days at a temperature of 10–12 °C, 14 days at a temperature of 4–6 °C and 21 days at a temperature of 1–3 °C in a refrigerator with controlled conditions. The relative humidity of the air is 90±3%. The maximum yield of commercial cilantro products is noted when using Xtend MA packaging/MH with an ethylene absorber Save Fresh: when stored for 5 days at a temperature of 10–12 °C – 95.7%, 14 days at 4–6 °C – 94.3%, 21 days at 1–3 °C – 91.7%. The maximum preservation of vitamin C in products is recorded in the Xtend packaging variant – 33.8 mg% with an indicator of 40.1 mg% immediately after cutting the greens. The use of Xtend packaging from the Israeli company StePac, which creates a modified atmosphere/modified humidity, together with an ethylene absorber based on potassium permanganate Save Fresh, allows you to reduce losses and ensure the preservation of the quality of cilantro greens of the Borodinsky vegetable variety during transportation, storage and sale.

ABSTRACT Maize is an important cereal and it is widely consumed in the world, both as food for humans and animals. Nitrogen (N) is a nutrient required in large quantities by maize, but unfortunately, soils are limited in meeting this need. Nodulating legumes can serve as a source of Nitrogen, because they are symbiotically associated with bacteria capable of fixing atmospheric N. Another important source of this nutrient is cattle manure, which is widely used in agriculture. The objective of the present study was to evaluate the effect of using legumes and cattle manure on the production as well as the microbial and biochemical quality of the soil used for maize cultivation. The experiment was conducted using a randomized complete block design, in a sub-subdivided plot scheme [(2x4) +2], two leguminous plants (pigeon pea and macassar bean), four doses of cattle manure (0, 20, 40 and 60 t ha-1) and two controls; one with mineral fertilization and the other cultivated without the use of fertilizers. Treatment using a manure dose of 60t ha-1 and pigeon pea legume, recorded higher dry mass production per plant. The increase in manure doses was directly proportional to the length and weight of the cobs for the two legumes. The enzymatic activities were affected by the different doses and legumes, with greater results being recorded at the 60 t ha-1 dose with the macassar legume. The use of legumes with manure improved maize production as well as the microbiological and biochemical quality of soils.
