In this study, the effects of nitrogen fertilizer and plant growth regulator (ethephon) application on leaf chlorophyl, stem height and diameter, stalk yield, total sugar and bioethanol of sweet sorghum were determined. Four nitrogen treatments 0, 100, 200 and 300 Kg Urea ha-1 and four ethephon concentrations 0, 800, 1000, and 1200 ppm were applied on sweet sorghum in a split plot on randomized...

the close to impossible correct controlling of the temperature and light intensity is the main limiting factors of growing plants in the plastic covered greenhouses. quality and vase life of cut flowers are mostly influenced by greenhouse temperature. alstroemeria needs cold temperature for growth and flowering. in the current study, the such changes in vase life and flower quality as stem leng...

In order to improve the quality of cut rose ‘Dolce Vita’, an investigation was performed with 20 treatments, 3 replications, and 2 plants in each replicate in a greenhouse with the open soilless culture system. The treatments included control (distilled water), putrescine (Put) at the rates of 1, 2 or 3 mM, spermidine (Spd) at the rates of 0.5, 1 or 1.5 mM, spermine (Spm) at the rates of 1, 2 o...

A Croatian indigenous cultivar of lavandin, Lavandula x intermedia 'Budrovka' (Lamiaceae) was studied for the phenolic acids, flavonoids, anthocyanins, procyanidins and total tannins, as well as total polyphenols content, in the flower, inflorescence stalk and leaf ethanolic extracts. Antioxidant potentials on these plant part extracts were assessed by the DPPH free radical scavenging activity,...

Extracts from raw materials from different plant parts, tissue-cultured plants, and callus cultures of Oroxylum indicum were analyzed for in vitro antioxidant activities determined by DPPH radical scavenging assay and evaluated for phytochemical profiles by TLC and LC-MS methods. The results were analyzed by principal component analysis (PCA) to evaluate the similarity. Stalk, pedicel, flower, ...

This study aimed to evaluate the influence of gibberellic acid on both concentration and time application seed production ability BU cauliflower-1. The experiment was conducted determine at five concentrations GA3: G0 = Control, G1 100 ppm, G2 200 G3 300 G4 400 along with four times different growth stages including T1 Foliar 3 weeks after planting, T2 4 T3 5 planting T4 6 planting. Results rev...

The substrates of composting with primary components of plant material such as cellulose, hemicellulose and lignin are rather difficult to biodegrade and reduce the availability of the other polymers by means of a physical restriction (Ladisch et al., 1983). Studies have showed that it is of great importance that increase of the microbial populations especially the lignocellulose-degrading micr...

Changes in gene expression during flower formation were studied in the long-day plant Sinapis alba. The day length dependence was exploited to synchronize flower formation in a large population of mustard plants. After an inductive light treatment, apices were harvested after different lengths of time, and changes in gene expression were analyzed. Two major groups of genes were identified whose...
