This study aimed at assessing the ability of sunflower to remediate zinc (Zn) impacted soils and partitioning factors Zn in soil-plants interactions. The research method used ex situ experiments using teddy bear seeds with 8 different treatments for each. began preparation sample soil media on garden soil, seeding seeds. was carried out six months starting August - December 2020, Helianthus ann...

Sunflower (Helianthus annuus) is a crop of increasing importance as source seed oil and proteins; nonetheless, the number studies on sunflower tissue culture somewhat limited. The development competent in vitro direct organogenesis protocol involves important basic steps regeneration. In our study, chemically sterilized seeds were planted induction media, 52.54 % germination efficiency was foun...

ABSTRACT-The critical period of weed control is a part of crop life cycle during which weeds must be kept weed-free to avoid yield losses due to competition. In order to evaluate the effect of deficit irrigation on critical period of redroot pigweed (Amaranthus retroflexus L.) in sunflower (Helianthus annuus L.), an experiment was carried out  as split plot ba...

application   of plants to remove heavy metals from soil (phytoremediation) is   expanding due to its cost-effectiveness as compared to conventional methods   and it has shown a great potential. since contaminants such as pb have a   limited bioavailability in the soil, methods to facilitate their   translocation to the shoots and roots of plants are required for efficient   phytoremediation. t...

Development, survivorship, longevity, reproduction, and life table parameters of the glassy-winged sharpshooter, Homalodisca vitripennis (Germar), were examined in the laboratory using three host plants, sunflower (Helianthus annuus L.), Chrysanthemum morifolium L., and euonymus (Euonymus japonica Thurb.). Females deposited similar-sized egg masses on all three plants. Hatching was highest with...

Systemic insecticides used for ornamental horticulture crops can protect all portions of a plant with long-lasting effects. However, they may be hazardous to pollinators foraging on contaminated nectar or pollen. Two model plant cultivars were chosen based upon their ability to produce large quantities of pollen or nectar, enabling examination of the level of nectar or pollen contamination (e.g...
