Recently much attention has been paid by horticulturists to light-emitting diodes as a new source of economical and spectral-selective light. The reason is mainly coming from their versatility in handling and mounting, long working time, wattage use efficiency and lower heat production. In this study we examined their potential in promoting seed germination and producing quality flower seedling...

To investigate the effects of silicon on the growth characteristics and the reduction of the powdery mildew damage to Zinnia (Zinnia elegans Jacq. ʻMagellanʼ), an experiment was carried out as a factorial experiment in the form of a randomized complete block design with two factors including eight treatments and three replications. The first factor included silicon concentrations at four levels...

This study was conducted to determine the characteristics of insect community flower visitors on several refugia plants. The research carried out in experimental field Faculty Agriculture, Jambi University and Laboratory Plant Pests, University. Samples flower-visiting insects were taken using yellow pan trap, pitfall sweep trap. obtained identified Characteristics communities plants calculated...

The heavy metal Cd seriously affects the growth and development of humans, animals plants, at same time, it has characteristics wide sources easy delivery. In this paper, effects contaminated soil remediation by biodegradable organic phosphonic acids HEDP, BHMTPMPA, HDTMPA ATMP on germination plants were studied. results showed that when concentration acid was 4%, Zinnia elegans Jacq. are best ...

Single cells were isolated mechanically from the mesophyll of adult plants and of seedlings of Zinnia elegans L. cv. Canary bird. When single cells isolated from the first leaves of seedlings were cultured in a liquid medium in the dark with rotation, they differentiated to tracheary elements with a reasonable degree of synchrony in the 24-hour period between days 2 and 3 after culture. The pro...
