The effects of natural dietary carotenoid supplementation of the maternal diet (tomato powder and marigold extract) on transfer to the egg yolk and on the development of the antioxidant system of the young quail liver in early postnatal life were investigated. Sixty Japanese quail (Coturnix coturnix japonica) were allocated to four treatment groups, each with three replicates consisting of four...

Root-knot nematode, Meloidogyne incognita, is the major limiting factor in tomato production in many regions of the world including Ethiopia. For its management, different plant species (botanicals) are being tried in different forms as an alternative to nematicides. The nematicidal potential of baker tree (Milletiaferruginea), bitter leaf (Vernonia amygodalina), parthenium (Parthenium hysterop...

Marigold belongs to the oldest medicinal plants, which had been used in the ancient times. At present it supplies its material of a great significance for pharmaceutical and cosmetic industry. The study was conducted in the period 2007–2009 on loess soil with the granulometric composition of silt loam. The aim of the experiment was to determine the effect of different nitrogen doses (0, 40, 80,...

Developmental patterns and survival of the cotton bollworm, Helicoverpa armigera Hübner (Lepidoptera: Noctuidae), a polyphagous insect pest, have been studied with reference to the effect of diet on major gut digestive enzymes (amylases, proteases, and lipases). Significant correlations between nutritional quality of the diet and larval and pupal mass were observed when H. armigera larvae were ...

the expansion of aquaculture in the last 10 years has made it an important source of protein worldwide.  however, increased production, and the culture intensification it carries, results in higher risk of infectious disease due to poor water quality and high stocking densities. disease has several negative effects on fish, which include reduced feed efficiency, impaired growth and death, repre...

Produk tanaman hias dikategorikan menjadi tiga macam, yaitu hamparan, gantung, dan pot. Marigold (Tagetes erecta L.), Pansy (Viola tricolor Viola odorata L.) merupakan jenis hamparan. Tanaman hamparan umumnya semusim yang ditanam di tanah atau menggunakan polybag. paling umum diperuntukkan sebagai lanskap dekorasi. Tujuan penelitian ini adalah mempelajari aspek hortikultura kelayakan ekonomi us...

The present study was conducted to evaluate the feasibility of enzymatic hydrolysis of carotenoid esters from Tagetes erecta using lipases from the yeast of Yarrowia lipolytica, with the aim of obtaining free lutein. The optimal concentrations of seven nutrients, considering the production of lipases relative to biomass (Yp/x) as the response variable, were determined in flask fermentations. In...

Bioassays with tomato and lettuce seeds and three plant experiments with marigold (Tagetes erecta L.) ‘Inca Gold’ were conducted in the laboratory and greenhouse, respectively, in order to investigate possibilities of determining and mitigating the effects of phytotoxins in pine tree substrate (PTS). PTS is produced by grinding loblolly pine tree (Pinus taeda L.) logs, and using as horticultura...

Colchicine was used as chemical mutagen for In vitro induction of polyploids. Nodal segments of In vitro grown marigold plantlets were cultured on MS medium supplemented with four different concentrations of colchcine (0.0%, 0.001%, 0.01% and 0.05%) for 12h, separately. After treatment, nodal segment were shifted to colchicine free MS medium for normal growth. Highest mortality rate (72.74%) an...

The suppression of Meloidogyne incognita by marigolds differed among six marigold cultivars and five soil temperatures. Tagetes signata (syn. T. tenuifolia) cv. Tangerine Gem and the Tagetes hybrid Polynema allowed reproduction and root galling when grown at 30 degrees C, and should not be used for control of M. incognita at temperatures close to 30 degrees C. Tagetes patula cultivars Single Go...
