In agriculture and gardening‚ hybrid seed is seed produced by cross-pollinated plants. In hybrid seed production‚ the crosses are specific and controlled. The advantage of growing hybrid seed compared to inbred lines comes from heterosis. To produce hybrid seed‚ elite inbred varieties are crossed with well-documented and consistent phenotypes (such as yield) and the resulting hybrid seed is collected. Another factor that is important in hybrid seed production is the combining ability of the parent

It is said that life comes from the forest‚ it is an area of land where flora and fauna are present. But because of different human activities‚ it started to become endangered. Therefore‚ Singapore made a greenhouse where different types of plants

PRACTICAL 6 Seed Plants (Gymnosperms and Angiosperms) OBJECTIVES: 1. To describe the features of seed plant life cycle and the concept of the dominant generation. 2. To describe the life histories and related reproductive structures of gymnosperms and angiosperms. 3. To summarize the features that distinguish gymnosperms and angiosperms. 4. To discuss the advantages of seed plants to dominate land and their evolutionary adaptations on land. EXPERIMENT 1: Gymnosperms INTRODUCTION: Gymnosperms

due to seed storage. Almost all of the species studied stored their seeds in dense woody fruit. In order for seed dispersal to occur leading to germination and sprouting‚ the fruit must be dense woody structure of the fruit must be dried. The drying of the fruit causes cracking allowing for the seeds to disperse and germinate. The addition of occasional fires to these communities allow for the drying of the fruit quicker than in its natural state (Lamont et al‚ 1999). Since the seeds of the fruit

important oilseed crop of the world. Groundnut seeds (kernels) contain 40-50% fat‚ 20-50 % protein and 10-20 % carbohydrate. Groundnut seeds are a nutritional source of vitamin E‚ niacin‚ falacin‚ calcium‚ phosphorus‚ magnesium‚ zinc‚ iron‚ riboflavin‚ thiamine and potassium. Groundnut kernels are consumed directly as raw‚ roasted or boiled kernels or oil extracted from the kernel is used as culinary oil). It is also used as animal feed (oil pressings‚ seeds‚ green material and straw) and industrial

process of seed dispersal? As plants undergo the process of ripening‚ they produce their own ethylene. Ethylene is a simple gas that is produced when fruit ripens (Nemec‚ 2008). When the fruit is ripe it is responsible for seed dispersal by attracting animals to the fruit‚ who consume it and then the seeds are dispersed in their fecal matter or whatever remains of the uneaten portion of the fruit that is left on the ground will be absorbed into the soil (Mauseth‚ 2003). Another means of seed dispersal

Introduction: The world’s total forest area is just over 4 billion hectares‚ which corresponds to an average of 0.6 ha per capita (Figure 1). The five most forest-rich countries (the Russian Federation‚ Brazil‚ Canada‚ the United States of America and China) account for more than half of the total forest area. Deforestation – mainly the conversion of tropical forest to agricultural land – shows signs of decreasing in several countries. Around 13 million hectares of forest were converted to

plants experiment‚ each group received the F1 generation seeds for their designated phenotypes. After receiving the seeds‚ the seeds were then planted into Styrofoam “quads” allowing the seeds to germinate. The seeds were then allowed to grow under a fluorescent light bank for 5 weeks. Throughout the growing of the seeds‚ each plant was continuously watered and adjusted the light bank to help the plant grow more efficiently. After letting the seeds germinate for approximately 14 days‚ after two or three

common pea seeds. The independent variable in this experiment is the replica of the acid rain (or the PH level)‚ while the dependent variable is the growth/and or germination of the pea seeds. This is a common problem in our environment today as rain continually gets more acidic. Our hypotheses in this experiment were that the growth of the pea seeds in the experimental or acid rain setup would be far less than that of the normal or control setup. Another would be that the experimental pea seeds would
