Chapter I Introduction A. Background of the study Lansium domesticum‚ also known as langsat‚ buahluku or lanzones‚ is a species of tree in the Mahogany family. The plant‚ which originates from western Southeast Asia‚ bears edible fruit. It is the provincial flower for the Indonesian province of South Sumatra.The tree is average sized‚ reaching 30 metres (98 ft) in height and 75 centimetres (30 in) in diameter. Seedling trees 30 years old planted at 8 x 8 meter spacing can have a height of 10

natural plant hormones and promote flowering‚ stem elongation and break dormancy of seeds. The hormone is used to thin the flowers so as to minimize the competitive effect of early fruiting on vegetation growth. The hormone is also used to increase the berry size by 60%. Gibberellin has also been used to produce seed less berries. Abscisic acid can also be added as it increases the abscission of mature fruits and seeds but only at high concentration. In the production of pineapple the hormone auxin

Alugbati Things You’ll Need: • Fresh fruit of alugbati • Mortar and pestle • Strainer • Bowl • 3 tbsp. vinegar • 1 tbsp. salt • 2 tbsp. rubbing alcohol • 1 tbsp. iodine • Bottle Writing ink can be made from many natural sources‚ such as the fruit juice of the alugbati plant. Alugbati‚ known in the U.S. as Malabar spinach‚ is commonly grown for its soft‚ spinach-like leaves and shoots. Alugbati is of African and East Asian origin. The juice of the fruits was reportedly used in ancient China

STUDY GUIDE INTEGRATED SCIENCE 10 PLANT UNIT DO YOU/CAN YOU…. 1. Understand that both plants and animals (eukaryotes) undergo a similar process for cellular division/reproduction? Both plant and animal cells undergo mitosis and meiosis. In plants‚ there is an alternation of generations; the gametophyte generation‚ where haploid gametes (pollen and ovule; sperm and egg) are produced via mitosis. Then the sporophyte generation combines these two into spores via meiosis‚ resulting in a diploid

The most difficult form of propagation is grafting. A lot of people probably think this is dumb or boring‚ but I think it is neat. Most people think the only way to grow plants is by seed‚ but you can also use leaves‚ and stems. Sean Russell says” Plants naturally use several different methods to multiply‚ from seeds to spores to shoots. Gardeners looking to speed the process along can propagate new plants from cuttings. Cuttings are a part of a plant’s roots‚ branches or leaves that‚ when cut and

completes its job of moving the pollen to the stigma‚ the grain travels down the pollen tube and joins with the ovule beginning the fertilization process. A plant producing fruit is dependent on fertilization‚ which is the result of pollination. 3. In total‚ a plant has five basic parts: Roots‚ stems‚ leaves‚ flowers‚ and fruits. Each part performs a major function for the plant. First‚ the roots‚ anchor the plant in the ground‚ and they absorb water and nutrients underneath the soil. The two types

undersides of the leaves and yellow spots form on the surface‚ if this is not controlled it will weaken the growth of the plant and it will be open to other diseases and may cause death of the plant. Powdery Mildew: This is a fungal disease that affects fruit trees‚ its leaves‚ stems and buds are coated with a white powdery coating‚ if this is not controlled it can spread and infect other plants. The disease is spread by spores which can be carried in long distances by the wind so it is important to keep

fine-textures soil having been proven to have a greater retention capacity of allelochemicals than coarse-textures soils. Also‚ allelopathic interactions include both promontory and inhibitory activities of phenolic allelochemicals and thus using seed germination as a bioassay parameter may be of little value.

Soak the seeds in water 24 hours before sowing. Two or three bitter gourd seeds can be sown together in a pit 2cms deep. Usually the seeds will germinate in 3-7 days. The germinated seeds can be replanted 45 cm to 50 cm apart on raised beds. In germination stage there are leaves with lobes and without lobes. 1.4.2 Branching stage: Removal of lateral
