This study was carried out to investigate the potential of Corn (Zea mays) for phytoremediation of soil contaminated with lead (Pb) and zinc (Zn). The Zea mays L. cv. Giza 2, Hordeum vulgare cv. Giza 123 and Lupinus termis cv. Giza 1 species were planted in poted soil contaminated with lead and zinc. Zea mays was also cultivated with Hordeum and Lupinus treated with lead and zinc. The results showed that growth decreased by (16.7, 48.63 and 23.56%), photosynthetic pigments decreased by (10.18, 22.38 and 10.9%) and total-N decreased by (30.0, 27.27 and 13.64%) in Zea, Hordeum and Lupinus, respectively as compared to control. Proteins profile in shoots of tested plants revealed qualitative and quantitative changes. Co-cultivated Zea with Hordeum and Lupinus treated with lead and zinc improvement all parameters. The evidences provided by this experiment indicated that Corn acts as an effective accumulator to zinc and lead.

Photosynthetic Pigment Content

The present study was conducted in order to evaluate the effects of NaCl on photosynthetic pigments and compatible solutes of Zea mays under salt stress. Seven NaCl regimes were used, 0mM, 25mM, 50mM, 75mM 100mM, 125mM and 150mM. Plants were analyzed on 15th day after salt treatment. A factorial experiment in a completely randomized block design (CRBD) with seven treatments and three replications were applied. From the data attained, we understand that in accordance with the increase in salinity, photosynthetic pigment content reduced drastically, whereas compatible solutes like proline, glycine betaine and sugar enhanced marginally. The accumulation of compatible solutes makes the plant survive against salinity stress.

El estudio tuvo como objetivo evaluar los parámetros cinéticos de la degradación in situ de la materia seca (MS), proteína cruda (PC) y la estimación del consumo mediante ecuaciones de predicción de MS de forrajes y alimentos concentrados en alpacas Huacaya (Vicugna pacos). Se trabajó con ensilado de maíz chala (Zea mays L) sin y con 1% de urea, cebada (Hordeum vulgare L), avena (Avena sativa L), salvado de trigo (Triticum aestivum L) y raspa de papa (Solanum tuberosum). Los alimentos (5 g en base seca) fueron colocados en sacos de nylon e incubados en el primer compartimento estomacal de dos alpacas fistuladas durante 0, 6, 12, 24, 48 y 76 horas. Se analizó la MS y la PC de los residuos de los sacos. La MS y la PC del salvado de trigo y de la raspa de papa presentaron potenciales de degradación elevados, así como la MS y la PC de la avena. Se destaca la mayor fracción no degradable de la PC del maíz chala sin y con urea y, por tanto, una menor degradabilidad de la PC. Las estimaciones del consumo por las alpacas generadas por las ecuaciones de tres estudios no son adecuadas a los alimentos en estudio.
