The effect of spongean alkaloids aaptamine (1), isoaaptamine (2), 9-demethylaaptamine (3), aaptanone (4), N-demethylaaptanone (5), and semisynthetic 4- N-methylaaptanone (6) was studied on the growth of seedlings roots of soy { Glycine max (L.) Merr.}, maize ( Zea mays L.), wheat ( Triticum aestivum L.), buckwheat ( Fagopyrum esculentum Moench), and barley ( Hordeum vulgare L.). It was shown that a stimulatory effect depends on the chemical structure of the compounds and species of crop plants. The structural motif of aaptamines 1–3 is essential for a stimulating activity on the growth of seedling roots of soy, maize, and wheat. The oxygenated 1,6-naphthyridine core of aaptanones 5 and 6 is important for their growth stimulating activity on barley roots.

Marine organisms are a rich resource of pharmaceutical active compounds which have a wide range of biological activity, including anticoagulant action, immunomodulating action, anti-tumor activity, antibacterial, antifungal and antiviral, anti-inflammatory, antioxidant, lipid-corrective activity etc. Antivir, Laminaran and Fucoidan derived from Laminaria cichorioides were tested in field conditions, as stimulants of growth and development of barley (Hordeum vulgare L.), wheat (Triticum aestivum L.) and buckwheat (Fagopyrum esculentum Moench). Research shows that stimulating effect depends on chemical structure of polysaccharides and on plant species. Antivir, Laminaran and Fucoidan at different concentrations stimulate growth, productivity and morphological traits (plant height, ear length, productive bushiness and others) of barley, wheat and buckwheat. Carbohydrate containing biopolymers derived from the sea algae effect differently upon rutin content in seeds and stems of buckwheat.

El objetivo de este trabajo fue conocer el régimen y riesgo agroclimático de heladas, por su época de ocurrencia y tipo genético, analizar su peligrosidad sobre los cultivos, y observar la tendencia en el período libre de heladas en los últimos 10 años (1996-2005), respecto del período 1975-1995, en Lugo. Se dispuso de un registro histórico de temperaturas mínimas, medidas en el abrigo meteorológico, de treinta y un años para la localidad de Lugo, Provincia de Lugo (lat.: 43° 03’ N; long.: 7° 30’ O y alt.: 480 m). Los resultados mostraron una mayor frecuencia de heladas primaverales (marzo, abril y mayo) que otoñales (octubre y noviembre). El escaso período libre de heladas, en la zona, puede resultar un impedimento para la difusión de cultivos frutícolas de hueso,  debiendo seleccionar aquellas variedades con mayor requerimiento en horas de frío.En la región, la producción hortícola prospera favorablemente, siendo los cultivos más utilizados, Col – Brassica oleracea L - y nabos (nabizas y grelos) – Brassica napus L -, en detrimento de cultivos anuales extensivos, tanto inverno primaverales, como trigo – Triticum aestivum L. o T. vulgare L. -, cebada – Hordeum vulgare L.-, o estivales como maíz – Zea mays L. -, girasol – Helianthus annus L., o soja - Glycine max L.

Em um Latossolo Roxo de Santo Ângelo (RS), e em um Podzólico Vermelho-Escuro de Eldorado do Sul (RS), ambos com textura argilosa, submetidos o primeiro à exploração com cultivo convencional de trigo (Triticum aestivum L.) e soja (Glycine max L.) e sob setária (Setaria anceps L.), e o segundo à exploração com capim-pangola (Digitaria decumbens L.), siratro (Macroptilium atropurpureum L.), plantio direto com aveia (Avena bizantina L.)/milho (Zea mays L.) e área sem vegetação, foi realizado o presente trabalho durante a safra de verão (1990/1991), com o objetivo de avaliar a estabilidade e a agregação do solo sob diferentes sistemas de cultivo. Constatou-se, nessa avaliação, que as gramíneas perenes por meio do seu sistema radicular tiveram grande efeito na agregação e estabilidade dos agregados do solo e que os teores de carbono orgânico, de ferro e alumínio-oxalato, argila e grau de dispersão tiveram também efeitos na agregação do solo, porém insuficientes para explicar as variações entre o diâmetro médio ponderado dos agregados sob os diferentes sistemas de cultivo.

Proteins and enzymes are informative biochemical markers frequently used in plant studies. The objective of this work was to present the studies with enzymes and proteins used as biochemical markers in crops and forest species—the articles prospected in the Scopus and Web of Science scientific databases in December 2020. The keywords were a combination of "agricultural" or "forest" with the Boolean operator and the enzymes' name: alcohol dehydrogenase/ADH, malate dehydrogenase/MDH, alpha-amylase/AMS, peroxiredoxin/PERX, and LEA proteins. Eighty-two articles addressed enzymes in agricultural or forest species were included in the analysis. The articles were published from 1976 to 2020, with an average annual publication of 12.2. Three hundred thirty-seven authors developed the annual percentage growth rate of 2.52% and articles. The most studied crops are Oryza sativa L., Glycine max L., Zea mays L., Hordeum vulgare L., specimens of the genera Triticum and Brassica. The forest species were Pinus, Picea, Nothofagus, Quercus, and Sorbus, and Fagus sylvatica L. The main tissues used for extraction are leaves, seeds, buds, and roots. The studies mainly deal with enzymes or proteins as markers associated with abiotic stresses and the structure or genetic diversity.

A qualidade do solo em plantio direto está relacionada ao sistema de culturas e pode ser avaliada pelo teor de matéria orgânica particulada (>53 ∝m), em razão da funcionalidade que essa fração proporciona ao solo e à sua sensibilidade às diferenças de manejo. Visando estudar a qualidade do solo em sistemas de culturas em plantio direto, este trabalho foi conduzido em experimento de longa duração (21 anos) em Latossolo Vermelho distrófico típico nos Campos Gerais do Paraná. Seis sistemas de culturas foram avaliados, em que trigo-TR (Triticum aestivum L.), soja-SO (Glycine max L.), milho-MI (Zea mays L.), aveia-preta-AV, para cobertura (Avena strigosa Schreb.), ervilhaca-ER, para cobertura (Vicia villosa Roth); azevém-AZ, para feno (Lolium multiflorum Lam.); ou alfafa-AL, para feno (Medicago sativa L.) compuseram os seguintes sistemas: TR-SO (referência), ER-MI-AV-SO-TR-SO, ER-MI-TR-SO, AV-MI-TR-SO, AZ-MI-AZ-SO e AL-MI (milho a cada três anos). Os estoques de carbono orgânico total (COT), nitrogênio total (NT) e de C e N na matéria orgânica (MO) particulada (>53 µm) e associada aos minerais (<53 µm) foram determinados em 0-5, 5-10 e 10-20 cm. O sistema semiperene AL-MI apresentou os maiores estoques de COT e NT na camada de 0-20 cm (63,6 Mg ha-1 COT e 4,6 Mg ha-1 NT), com incrementos anuais de 0,23 Mg ha-1 COT e 0,03 Mg ha-1 NT, em relação ao sistema TR-SO. O sistema AL-MI também teve os maiores estoques de C e N na MO particulada nessa camada (12,5 e 0,91 Mg ha-1, respectivamente), por causa da maior adição de fitomassa pelas raízes e a proteção física dos resíduos orgânicos. Os menores estoques de COT e NT na camada 0-20 cm ocorreram no sistema ER-MI-TR-SO (57,8 Mg ha-1 COT e 4,03 Mg ha-1 NT), sem apresentar incremento anual em relação ao sistema TR-SO. Os estoques de C e N na MO particulada foram de 10,4 e 0,67 Mg ha-1, respectivamente. Essa tendência repetiu-se para as camadas individuais, com diferença significativa entre os sistemas na camada de 0-5 cm e não significativa, para as de 5-10 e 10-20 cm. Na média dos sistemas, a MO particulada contribuiu em torno de 30 % para o estoque total de C na camada 0-5 cm. Rotação de culturas com espécies que tenham sistema radicular ativo por mais tempo, como o sistema semiperene AL-MI, tem potencial de incrementar o estoque total de C e N, especialmente da fração MO particulada, proporcionando funcionalidade ao solo e, consequentemente, qualidade.
