Known to many as japgrass‚ cogongrass was accidentally introduced into Alabama near Grand Bay about 1911 as seed in packing materials from Japan (4). Purposeful introductions soon followed in other areas of Alabama‚ Mississippi‚ and Florida‚ with the primary intent for forage production (1‚4). Horticultural varieties of cogongrass continue to be sold under the

EXERCISE 5 PHYTOGRAPHY: THE FRUIT Name: JOHN REY CORPUZ Score: Date:APRIL 2‚ 2013 Section: I. INTRODUCTION The fruit is a matured ovary containing one or more seeds. It is composed of the exocarp‚ mesocarp and the endocarp. Many floral parts aside from the ovary are persistent and therefore could still be seen in mature fruits. Some examples are the receptacles (apple‚ sepals (eggplant)‚ style (corn) and many more. There are several variations of the

Acidic medium was needed for in vitro reproductive development with pH 4.5-6.5 the most favorable. A pod formation frequency of 81%‚ a seed production rate of 90% (from pods recovered in vitro)‚ and plant recovery of 33% were obtained for a medium containing 1.0 mg L-’ NAA and 0.5 mg L-’ GA‚ plus 60 g L-’ sucrose at pH 5.8. In vitro-recovered cotyledonaryembryos between 4 and 10mm long

Soil properties: Some physical and chemical properties of the soil were measured‚ which are presented in Table 1. The availability of nutrients and even contaminants depends on the degree of soil acidity. The most suitable pH for soil microorganism’ activity is 7‚ as nutrient solubility depends on soil pH changes (Riser-Roberts‚ 1998). The soil used in the present study has neutral pH and therefore does not limit the activity of microorganisms or the solubility of nutrients except for phosphorus

Effects of Sildenafil on Plant Growth using Brassica rapa seeds Introduction: Plant growth and development are affected by an overwhelming amount of factors in their environment but all these factors can be manipulated and given the perfect conditions the plant can grow to reach its peak size and potential. Rate of plant growth intrigued my fellow group members and I so it was decided that growth in mm as well as germination of the seed itself would be studied. With research being conducted into

Monteverde is located in Puntarenas‚ Costa Rica‚ an approximately four-hour journey from the Central Valley. Costa Rica is known for its diverse variety of flora and fauna. Among them‚ Orchids are one of the main attraction. The majority of orchids in Costa Rica are found in Monteverde Orchid Gardens. The Garden alone accommodates over 500 species of orchids from a wide range of color and shape. Monsoon is said to be the best season of the year for orchids.

Procedure of the experiment: Two pots are prepared by filling them with soil‚ and are labelled as A and B. A few (2-3) mustard seeds are sown in each of them. The conditions necessary for germination of seeds such as oxygen‚ moisture (water)‚ and optimum temperature are provided in order to allow them to germinate
