  • What Is The Effect Of Salt Concentration On Seed Germination

    seeds were treated with 3 different salt concentrations which are 0.1M, 0.2M and 0.3M. Each of the genotypes was placed in 0M salt concentration as well which acts as the control. We used 10 ml of distilled water for the control and mixed 1ml of NaCl with 9 ml of distilled water for 0.1M salt concentration. Next, for 0.2M and 0.3M salt concentration, we mixed 2ml of NaCl with 8 ml of distilled water, and 3ml of NaCl with 7 ml distilled water respectively. Next, we placed a piece of tissue in the Petri dishes and sprinkled the solution in each Petri dish. Then, we divided each Petri dish into 4 compartments and placed 10 seeds of the same genotype in each compartment to set the replicates for each genotype. We observed the number of green cotyledons that came out once the seed germinated and counted them (De-Rose Wilson and Gaut, 2011). The seed germination for each genotype and concentration were recorded every two days for 14 days. For the experiment, we tested the different mean of germination for each seed genotype in different salt concentration using Kruskal-Wallis test implemented in R to calculate the p-value. The raw data was log-transformed as it didn’t satisfy the normality assumption (DeRose-Wilson and Gaut, 2011). Results Based on the observation that we made, it was found that all of the genotypes only have their seed germinated for 0M and 0.1M salt concentration. None of the seed germinated for salt concentration 0.2M and 0.3M. Table 1 shows that the…

  • Advantages And Disadvantages Of Asexual And Sexual Reproduction In Plants

    angiosperms. Their success results, in part, from two innovative structures: the flower and the fruit. Flowers are derived evolutionarily from modified leaves. The main parts of a flower are the sepals and petals, which protect the reproductive parts: the stamens and the carpels. The stamens produce the male gametes, which are pollen grains. The carpels contain the female gametes, which are the eggs inside ovaries. The walls of the ovary thicken after fertilization, ripening into fruit that can…

  • Case Study Of Theobroma Cacao

    The cultivar cocoa, Theobroma cacao L is the family of Sterculiaceae. Cocoa is a dicots, it have two cotyledons, taproot and five floral parts. During seed germination, the initial grow is tap root and followed by hypocotyls up above ground level. It take three month to develop mature tree root. In duration, the stem will develop based on growth the cotyledon. The plumule will appear, its depend on emerge of cotyledon and the first four leaves will follow growth. The lateral branch of cocoa tree…

    which they are acting (Prakash, Upadhyay, Singh, & Singh, 2007;Kim et al., 2006; Shi, Nam, & Ma, 2010). Black mung beans were found to be excellent dietary sources of natural antioxidants for health promotion; meanwhile, these mung bean sources exhibited great potential to be developed into functional foods or nutraceutical ingredients for maintaining glycemic control and alleviating diabetic complications(Yao, Y., Yang, X., Tian, J., Liu, C., Cheng, X., & Ren, G.2013). Peas, more specifically…

  • Gram Seeds Embryo Research

    soil seed normally begins to germinates then they get an appropriate range of soil,temperature and when water and oxygen are available.During germination the seeds absorb water either through the micropyle(pore like opening) it is present or through the testa(outer seed coat) when it is permeable.The entry of water actives the embryo cells.Ones soaked for the required time,the part of the plant that first emerges from the seed is the embryonic root known as the radicle allows the seedling to…

  • The Importance Of Germination In Plants

    examples of these micro-organisms are bacteria, fungi and viruses, although visible to the naked eye, the symptoms include wilting, yellowing, stunting and abnormal growth patterns (Encyclopedia, n.d.). There is an 80% chance that plant diseases such as fungi can affect a seed. It grows on dead plant tissue but can penetrate plant tissue or grow on plant surface. The fungal spores, however act like seeds and can be spread by wind, water, soil and animals to other plants, and is able to populate…

  • Germination Lab Report

    absorbs nutrients and water. The hypocotyl is a hooked shaped structure that can be found on dicots. It is the first thing to appear from the soil in most plants and it is the beginning of the stem/shoot. (pg544 - 589) The shoot is responsible for photosynthesis in the plant which is how plants make their own food and is why they are autotrophs. Both angiosperms and gymnosperms are seeded plants. Angiosperms are flowered plants and they are separated into monocots and dicots.(pg580-590)…

    and amounts of proteins, cellulose, nucleic acids steadily increase in the growing region of the seed. The first visible sign of growth is the radicle that emerges from the micropyle and is positively geotropic in nature. It forms the root system of the plant. The plumule is the next structure that emerges. It is positively phototropic and forms the shoot system of the plant. 2.7.2 Stages of seed germination Step 1: Water imbibition results in rapture of seed coat, uniform distribution is…

  • Lab Report: Genetic Analysis In Plants

    the corn seedling experiment and using the information from that we answered more questions. For procedure 2, we were provided with a container of kernels that we classified and counted the F2 progeny and recorded the data. We sorted the seedlings into four different categories: yellow and round, yellow and wrinkled, purple and round, purple and wrinkled. Again we analyzed our data by using a chi-square test and answered questions about the data we collected. In procedure 3, we were given…

  • Cellular Respiration Essay

    which a seed emerges from a period of dormancy and starts to sprout. For germination to occur, a seed requires a combination of: Oxygen (for aerobic respiration), Water (To metabolically activate cells), and a warm environment (to optimize enzyme activity). High temperatures will denature essential enzymes, whereas insufficient thermal energy will prohibit reactions from occurring. A person may wonder why seeds are often buried underground. The extent to which germination has progressed can be…
