The propagation of plants is a very important aspect of life due to the importance of plants. The ways in which plants can be propagated are discussed due to the time that it takes to grow a plant. The fastest and most efficient way to grow plants is wanted by all the industries that produce the plants for society. I have decided to determine the fastest way of propagation by testing how cuttings

Examine ways for the biological control, of a foreign plant, with its natural enemy without harming the native plants of North America. To determine if any stage in the beetle, Galerucella calmariensis and Galerwcella pusilla life cycle will feed only on purple loosestrife, Lathrum salicaria, or if it will feed on agricultural crops in North America.

This project was performed to determine how different concentrations of salt water effect plants. The test that will be performed will prove which concentration will have the worst effect. The hypothesis is that by measuring the plants growth each day, the largest concentration of salt will harm the plants the most.

The hypothesis of this experiment is that the cauliflower plant that is watered with the water containing Epsom salt will have the shortest growth height and the smallest root system. The purpose of this experiment was to determine the effect of different salts on the height growth and root systems of cauliflower plants.

We established a 13-week greenhouse experiment based on replicated microcosms to test whether the effects of defoliation on grassland plants and soil organisms depend on plant species composition and the presence of arbuscular mycorrhizal (AM) fungi. The experiment constituted of three treatment factors - plant species composition, inoculation of an AM fungus and defoliation - in a fully

PURPOSE The purpose of this experiment was to determine how diseases effect pea plants, and what disease is most common. I became interested in this idea because I wanted a project that related to where I live, and I wanted to find out more about my dadÂ’s work at Del Monte and what goes on there. Pea growers can use the information gained from this experiment so that they know what
