Abstract Basil (Ocimum basilicum L., Lamiaceae) is an herbal species cultivated primarily for culinary and aromatherapy. plant height could reach more than 60 cm, the plants tend to elongate, particularly in low-light environments. Our current study examined potential uses of growth retardant paclobutrazol control sweet basil improve potted basil’s ornamental quality. The treatment tested was c...

Steinernema carpocapsae Weiser All strain was compared to Steinernema riobravis Cabanillas, Poinar, and Raulston for control of the root weevil, Diaprepes abbreviatus (L.), in the laboratory and in potted citrus. In the laboratory bioassay, D. abbreviatus larvae were exposed to 30, 60, and 120 nematodes/cm(3) in sand. Insect mortality 1 week after application was greater (P </= 0.05) for S. rio...

We hypothesized that a parasitoid of an herbivore would be attracted to large rather than small patches of plants that provide food for the herbivore. We conducted experiments to determine whether such parasitoids would be more likely to find and/or less likely to leave large patches of their victims' host plants. We also examined whether prey density (independent of patch size) affects plant f...

Chemical plant growth regulators (PGRs) are used in the production of ornamental potted and bedding plants. Growth control is needed for maximizing production per unit area, reducing transportation costs and to obtain a desired visual quality. However, the use of PGRs is associated with toxicity risks to humans and the environment. In many countries the availability of PGRs is restricted as few...

Physical mutagenesis is an effective mutational breeding method for improving various growth and floral characteristics of ornamental plants. The experiment was undertaken with objective to investigate the effect dosages gamma irradiation on survivability, Jasminum officinale plants raised by rooted cuttings. 60CO Gamma source at Horticultural Crop Research Developmental Institute, Gannoruwa us...
