Effect of Adding Different Levels of Turmeric Root Powder and Carnation Flowers to The Diet on Some Blood and Microorganisms Traits of Broilers Under Heat Stress Condition

The current study was carried out on a poultry farm which belongs to the Animal production department - College of Agriculture - University of Kufa, for a period of 35 days started from October 10 to November 13, 2020 for 5 weeks to find out the effect of adding different levels of turmeric root powder and carnation flowers to the diet on some productive traits of broilers. in the experiment, 360 broiler chicks were used, one-day-old Ross-308 hybrid, The chicks were divided randomly into 6 treatments (60 chicks/treatment) by 3 replicates per treatment, with 20 chicks for each with an average initial weight of 40gm and the treatments were as follows: 0, 3, and 5 gm/kg diet of turmeric root powder for treatments T0, T1, T2, as well as 3 and 5 gm/kg diet fodder of carnation flower powder for treatments T3 and T4, respectively.

Facile Controlling of the Physical Properties of Zinc Oxide and Its Application to Enhanced Photocatalysis

In this study, the physical properties of ZnO were facile controlled by the synthesis method with the addition of capping and precipitation agents. As-prepared ZnO samples had different morphologies such as carnation flower-like ZnO (CF-ZnO), rose-flower-like ZnO (RF-ZnO), rod-like ZnO (R-ZnO), and nanoparticle ZnO (N-ZnO) and were characterized by SEM, XRD, N2 adsorption/desorption isotherms, FT-IR, and DR/UV-vis. All samples had a crystallite structure of hexagonal wurtzite type. The CF-ZnO and RF-ZnO samples had the hierarchical structure like a carnation flower and a beautiful rose, respectively. R-ZnO was composed of many hexagonal rods and few spherical particles, while N-ZnO microstructures were made up of nanoparticles with approximately 20–30 nm, exhibiting the largest surface area, pore volume, and pore width among as-prepared samples, and their crystal size and bandgap energy were 17.8 nm and 3.207 eV, respectively. The catalytic performances of ZnO samples were evaluated by degradation of Tartrazine (TA) and Caffeine (CAF) under low UV irradiation (15 W). N-ZnO showed a high photocatalytic activity compared to other samples. Besides, the reaction kinetics was investigated by the first-order kinetic model, and the catalytic performance of ZnO was evaluated through several organic pollutants.

Effect of inoculation of Bacillus strains on flowering of carnation (Dianthus caryophyllus)

The carnation flower (Dianthus caryophyllus) is one of the most accepted and distributed worldwide, for its production, fertilization and the application of phytohormones have been optmized, thereby seeking to improve flower quality. However, little has been tested on the effect of the application of plant growth promoting bacteria. In the present work, carnation plants cv. Lilliput, were inoculated with 5X107 cells of Bacillus megaterium M6 and Bacillus subtilis P12, both individually and in interaction (M6 x P12), registering agronomic parameters related to flowering. The results showed that none of the inoculations had an effect on the percentage of flowering plants, neither on the height nor the diameter of the flower, only P12 increased flower number per plant by 38 %, compared to the control without inoculation. Being the period between 96 and 127 days after transplantation (dat), where tha highest number of total flowers was recorded (70) with respect to the other treatments (M6:36, M6 x P12: 24 and control: 32). In conclusion, Bacillus subtilis P12 has a promoter activity to improve the flowering of carnation plants.

Potential growing model for the standard carnation cv. Delphi

The cut flower business requires exact synchronicity between product offer and demand in consumer countries. Having tools that help to improve this synchronicity through predictions or crop growth monitoring could provide an important advantage to program standards and corrective agronomic practices. At the Centro de Biotecnología Agropecuaria, SENA (SENA's Biotechnology, Agricultural and Livestock Center), located in Mosquera, Cundinamarca, a trial with standard carnation cv. Delphi grown under greenhouse conditions was carried out. The objective of this study was to build a simple model of dry matter (DM) production and partition of on-carnation flower stems. The model was based on the photosynthetically active radiation (PAR) MJ m-2 d-1 and temperature as exogenous variables and assumed no water or nutrient limitations or damage caused by pests, disease or weeds. In this model, the daily DM increase depended on the PAR, the light fraction intercepted by the foliage (FLINT) and the light use efficiency (LUE) g MJ-1. The LUE in the vegetative and reproductive stages reached values of 1.31 and 0.74 g MJ-1, respectively. The estimated extinction coefficient (k) value corresponded to 0.53 and the maximum FLINT was between 0.79 and 0.82. Partitioning between the plant vegetative and reproductive stages was modeled based on the hypothesis that the partition is regulated by the source sink relationship. The estimated partition coefficient for the vegetative stage of the leaves was 0.63 and 0.37 for the stems. During the reproductive stage, the partitioning coefficients of leaves, stems and flower buds were 0.05, 0.74, and 0.21, respectively.
