Hypothesis: The same object dropped onto the same surface at varying heights will yield a correspondingly greater quantity and quality of spray.
Other findings include that, indoor spray was most consistently applied in the bathroom and kitchen; outdoor sprays were consistently more often applied by male household members, while indoor sprays were not; quantity of indoor spray pesticide products purchased may not be a substitute measure of use frequency of indoor spray.
In addition, the GIS can be used to generate a quantitative exposure opportunity index that accounts for quantity of herbicide sprayed, distance, and environmental decay of a toxic factor such as dioxin, and is flexible enough to permit substitution of other mathematical exposure models by the user.
These results indicate that pollen quantity per anther is a main factor affecting pollen quantity per inflorescence of spray cut chrysanthemum, while the number of disk florets per inflorescence has little effect on pollen quantity per inflorescence.
Pollen quantity per inflorescence of spray cut chrysanthemum is jointly determined by pollen quantity per anther and the number of disk florets per inflorescence, but pollen quantity per anther is the main factor.
The SI report says Singh ordered quantities of the spray last November and quotes the three-time major champion claiming he takes it: "Every couple of hours, every day".
Therefore, we are the first time to carry out a systematic investigation on factors controlling quantity of pollen dispersal of spray cut chrysanthemum in this study using four cultivars with different quantity of pollen dispersal, i.e. 'Qx-097' with high quantity of pollen dispersal, 'Noa' with low quantity of pollen dispersal, 'Qx-115' and 'Kingfisher' without pollen dispersal.
Therefore, the degree of anther cracking is one of the main factors affecting quantity of pollen dispersal of spray cut chrysanthemum through controlling the capacity of pollen dispersal.
Therefore, in order to obtain some valuable information for developing spray cut chrysanthemum with less-dispersed or non-dispersed pollen in the future breeding programs, we here investigated the factors affecting quantity of pollen dispersal of spray cut chrysanthemum with four cultivars, i.e. 'Qx-097', 'Noa', 'Qx-115', and 'Kingfisher', that have different quantity of pollen dispersal.
Our overall aim was to reveal the main causes influencing quantity of pollen dispersal of spray cut chrysanthemum, and the expected outputs will provide valuable information for effectively developing new cultivars with less-dispersed or non-dispersed pollen in the near future.
