ManyPhoenix dactylifera(date palm) cultivars are grown in the arid and semiarid regions of the world, including Saudi Arabia.P. dactyliferais highly tolerant to salinity stress. To investigate the response of Khalas cultivar ofP. dactylifera, two-month-old plants were treated with sodium chloride (50, 100, and 150 mM NaCl) for three months. Our result showed that proline content was higher in all treated plants compared to control plants. Thiobarbituric acid reactive substances (TBARS) were increased at 100 and 150 mM NaCl treatments; however, the result was found nonsignificant between control and plants treated at 50 mM NaCl. Similarly, enzyme activities of catalase (CAT) and superoxide dismutase (SOD) were 0.805 and 0.722 U/mg protein/min, respectively, and were greater at 100 and 150 mM NaCl treatments compared to the control plants. Total chlorophyll content and fresh weight of shoots and roots decreased substantially with the increase of salinity. A cDNA start codon-targeted (cDNA-SCoT) marker showed a variation in different gene expressions profiling between treated and untreated plants under various NaCl concentrations.

ABSTRACT Date palm accumulates a wide range of secondary metabolites high in nutritional and therapeutic value. In the present study, date palm (Phoenix dactylifera L., cv. Shaishi) shoot-tip-induced callus was used to establish cell suspension cultures in Murashige and Skoog (MS) liquid medium containing 1.5 mg L-1 2-isopentenyladenine (2iP) and 10 mg L-1 naphthaleneacetic acid (NAA). To study the growth kinetics, cultures were maintained for 12 weeks during which weekly measurements were carried out to determine the biomass accumulation based on packed cell volume (%), fresh weight and dry weight (g). In addition, weekly determination of polyphenols (catechin, caffeic acid, kaempferol, and apigenin) was carried out using high performance liquid chromatography (HPLC). The 11-week-old culture was found highest in the production of biomass (62.9 g L-1 fresh weight and 7.6 g L-1 dry weight) and polyphenols (catechin-155.9 µg L-1, caffeic acid-162.7 µg L-1, kaempferol-89.7 µg L-1, and apigenin-242.7 µg L-1) from the cell suspension cultures. This is the first report on the production of polyphenols from the cell suspension culture of date palm. This study facilitates further development of large-scale production of polyphenols and the utilization of bioreactors.

E-mail: [email protected]     1 RESUMO   Objetivou-se com o presente trabalho, avaliar o crescimento e acúmulo de biomassa de plantas de milheto irrigadas com água salina em solo com diferentes coberturas. O experimento foi realizado em agosto de 2018, a pleno sol na horta didática da Universidade da integração internacional da Lusofonia Afro-Brasileira (UNILAB), Redenção, Ceará. O delineamento experimental foi inteiramente casualizado (DIC), em esquema fatorial 5x4, com 4 repetições. O primeiro fator referente aos valores de condutividade elétrica da água de irrigação - CEa: A1 (1,0 dS m-1), A2 (2,0 dS m-1), A3 (3,0 dS 11 m-1), A4 (4,0 dS m-1) e A5 (5,0 dS m-1), versus as coberturas adotadas, C1 (sem cobertura-controle), C2 (palha de arroz), C3 (bagana de cana-de-açúcar) e C4 (resíduos vegetais de espontâneas). Aos 35 dias após a semeadura, foram avaliadas: altura das plantas (AP), número de folhas (NF), diâmetro do colmo (DC), comprimento de raiz (CR), área foliar (AF), matéria seca da parte aérea (MSPA), da raiz (MSR) e total (MST), pH do solo e a condutividade elétrica do extrato de saturação do solo (CEes). O aumento da condutividade elétrica na água de irrigação, promoveu aumento da salinidade no extrato de saturação do solo, assim como reduções na emissão do número de folhas no milheto e o uso da cobertura morta amenizou os efeitos da salinidade contida na água, nas variáveis: MSPA, MSR, MST, DC e AP, sendo a cobertura de casca de arroz a alternativa mais eficiente na atenuação desses efeitos.   Palavras-chave: Penissetum glaucum L., estresse salino, proteção do solo     LIMA, A.

CULTIVATION OF MILLET IRRIGATED WITH SALINE WATER IN DIFFERENT MULCHES     2 ABSTRACT   The objective of this work was to evaluate the growth and accumulation of dry matter of millet plants irrigated with saline water in soil with different mulches. The experiment was carried out in August 2018, under full sun in the didactic garden of the University of the International Integration of Afro-Brazilian Lusophony (UNILAB), Redenção, Ceará. The experimental design was completely randomized (DIC), in a 5x4 factorial scheme, with four replicates. The first factor referring to the values of electrical conductivity of the irrigation water: A1 (1.0 dS m-1), A2 (2.0 dS m-1), A3 (3.0 dS m-1), A4 (4.0 dS m-1) and A5 (5.0 dS m-1), versus the coverages adopted, C1 (without cover), C2 (rice straw), C3 (sugarcane bagana) and C4 (vegetable spontaneous waste). At 35 days after sowing, plant height (AP), number of leaves emitted (NF), stalk diameter (DC), root length (CR), leaf area (AF), shoot dry matter (MSA), root dry matter (MSR), total dry matter (MST), soil pH and soil saturation extract electrical conductivity (CEs) were assessed. The increase in the electrical conductivity in the irrigation water promoted an increase in salinity in the soil saturation extract, as well as reductions in the number of leaves in the millet, and the use of the mulch reduced the effects of the salinity contained in the water in the following variables: MSPA, MSR, MST, DC and AP, with rice husk coverage being the most efficient alternative to mitigate these effects.   Keywords: Penissetum glaucum L., saline stress, soil protection.

The growing need for clean energy and food production are favoring the use of underused spaces, such as rooftops. This study aims to demonstrate the compatibility of the use of rooftops both for the production of photovoltaic energy and for the production of food, despite the fact that both compete for the same resource, sunlight (rooftop agrivoltaic). In the experiment reported in this study, which was carried out in Almería (Spain) during the spring and summer of 2021, three shade treatments were tested for a lettuce crop, produced by photovoltaic modules with different arrangements: concentrated shade (CS), scattered shade (SS) and full sun (FS). This experiment was repeated in two seasons with high radiation levels and temperature. The results show that in these environmental conditions, the cultivation of plants that demand little sunlight, such as lettuce, is compatible with the shading produced by photovoltaic panels. In addition, it is shown that the same percentage of the area covered with shade (22%), but using mini-PV modules arranged in patterns, improves the productivity (fresh weight, dry matter, number of leaves, maximum length and dry matter of roots) of lettuce cultivation, both in spring and summer.
