due to the importance of weed control and the limitations of mechanical methods in some places, in this research the water jet cutting for weed control was investigated. the cutting tests were performed on camel thorn weed in shahid bahonar university of kerman. the water jet pressure of 90 bars was achieved with the aid of a suitable pump. the cutting time was studied in a completely randomize...

Present work reports the biological activities of P. hysterophorus leaf, stem, flower, and root. Dried samples were sequentially extracted with many solvents. Hexane (HX), benzene (BZ), and chloroform (CH) extracts of leaf showed considerable antibacterial activity against Streptococcus mutans (MTCC 497), Proteus vulgaris (MTCC 7299), and Salmonella typhi (MTCC 3917). Flower extracts exhibited ...

In this paper, we handle a remote ikebana (i.e., flower arrangement) system with olfactory and haptic media. In the system, a teacher or a student can hold a flower, adjust the length of the held flower’s stem with a pair of scissors, and impale the flower on a flower pinholder in a 3-D virtual space. We investigate the influence of the size of smell space (defined as a sphere in which we can p...

Two new species of Cousinia are described from Iran. Cousinia bornmulleriana from the west that can be placed in sect. Haussknechtii based on some key characters such as flower numbers, phyllary numbers and the inflorescence form traits. This species can be also compared with its closest relative C. haussknechtii. and C. karkasensis. The second new species, C. semnanensis, from North East of Ir...

Computer Graphics (CG) and Virtual Reality (VR) technologies have rapidly improved in recent years. It enabled us to develop some useful systems such as air hockey, catch ball, tennis and horseback riding for sports field, surgical simulations and support systems for medical field, calligraphy and flower arrangement for educational field. The good training systems have force feedback for users ...

The antimicrobial activity of plant hidroethanolic extracts on bacteria Gram positive, Gram negative, yeasts, Mycobacterium tuberculosis H37 and Mycobacterium bovis was evaluated by using the technique of Agar diffusion and microdilution in broth. Among the extracts evaluated by Agar diffusion, the extract of Bidens pilosa leaf presented the most expressive average of haloes of growth inhibitio...

gladiolus (gladiolus grandiflorus l.), a popular bulbous cut flower, has high demand in both domestic (pakistani) as well as international markets. five potential, exotic cultivars of gladiolus, ‘cantate’, ‘corveira’, ‘eminence’, ‘essential’ and ‘fado’ were evaluated to determine the cultivar effects on yield and quality, to compare their relative performance and recommend their suitability for...

The present investigation Efficacy of plant growth retardants on growth, flowering, yield and shelf life dahlia (Dahlia variabilis L.) cv. Shubhra was conducted in Research Field, Department Horticulture, Sam Higginbottom University Agriculture, Technology Sciences, Prayagraj, during winter season (2022-23). experiment laid out Randomized block design (RBD). There are 9th treatment combination ...

This study was carried out to evaluate the effects of different plant growth regulators on ornamental sunflower plant. The seedlings belonging Helianthus annuus L. cv. Sunsantion F1 were planted in plastic pots (2 L) containing peat:perlite (1:1, v/v) medium at four true leaf stage. Spray treatments aminoethoxyvinil glycine (AVG; 250 and 500 ppm), promalin (5 10 thidiazuron (TDZ; 5-10 µM), ethe...
