Germination

The Effects of Salinity on Germination Rate Introduction Germination of a seed begins when it is provided water and is in the appropriate conditions. Seeds imbibe the water and the enzymes hydrate, the hydrated enzymes increase metabolic activity to produce energy for the growth process. The root is the first thing to break from the seed and this is when the sed can be officially considered germinated. The environment is what triggers the germination of the seed. How does increasing the…

Germination is a process that seeds undergo when the correct exterior conditions are met and water is introduced, allowing seeds to begin the process of growing into a fully mature plant. When enough water is near the seed it enters the cell by osmosis, specifically a type of osmosis called imbibition when the seeds are in a dormant state. The flow of the water into the seed reinstates a hypotonic environment.This recreates turgor pressure inside the cells causing the cell walls to be rigid,…

Impact of Salt on Seed Germination Introduction Germination is a key event in a plant’s lifetime and controlled by two main factors which are water and salt stress (Yuan et al., 2016 and Vallejo et al., 2010). Salt stress affects plant growth and crop production by causing osmotic and ionic stress in plants. Alonso-Blanco et al in 2009 reported that less study was made on the traits in Arabidopsis thaliana despite the immense genetic variation present in the species and the importance of seed…

The original hypothesis, “If ascorbic acid has positive effects on radish seed germination, then radish seeds germinated with ascorbic acid concentrations of 0, 100, 300, and 500 parts per million (ppm) solutions will exhibit longer seed radicles (measured in millimeters) than control seeds germinated in distilled water alone” was incompletely supported. For example, Graph 1 shows the Control trial achieved the greatest average length (31.5 mm) by the end of the experiment in comparison to all…

Two different types of seeds, Radish and Cactus, were grown using different concentrations of Gibberellic acid, to see how it would affect their germination time. The amount of germinated seeds were counted each day, and then compared with the combined data from the rest of the class. Gibberellic acid is a metabolic byproduct of the “Gibberella Fujikuroi” fungus. It caused the stems of rice to grow more rapidly than usual, so rapidly that the plant would collapse (Riley 1987) (Gupta, Chakrabarty…

GA solution had the fastest rate of germination, followed by 1000 ppm., 125 ppm. and the control group. Ferocactus histrix During the 18 days of the experiment, not all of the seeds of the Ferocactus histrix have germinated. 95% of the seeds have germinated in the control group, 90% have germinated…

dextrose aqueous solutions in comparison to the radicle lengths since the P values were less than 0.05. Although, there was a statistical increase in radicle length with the comparison to the control. If these seeds were able to reach the average seed germination process in ten days, the radicle lengths would have increased within the two different sugars. While conducting the experiment we used nine clear small circular containers. Each circular container was filled with four non-germinated…

CONCLUSIONS RESULTS The aim of the investigation was to evaluate not only if the species E. microcorys had exhibited allelochemicals that would have prevented the germination of R. sativus seeds, but also to specifically find if there had been a parallel between the changing concentration of E. microcorys to the seed germination. The resulting data supported the stated hypothesis to a substantial extent. The hypothesis was supported because when the concentration of concocted E. microcorys…

An Investigation of the Effects of Cytokinins during the Germination of Brassica rapa Seeds Germination is a vital stage in a plants life, but it also plays a significant role in other animals’ (including humans) life cycle. It is the process in which a new plant grows from a seed. Due to the fact that plants are autotrophs; they use the process of photosynthesis to transform sunlight and make their own food. Germination occurs in gymnosperms and angiosperms when the seed is using its own…

Neffati M, and Tlig T (2007). Germination responses of Diplotaxis harra to temperature and salinity. Flora 203: 421–428 2a) Successful colonization of plant species is reliant on fruitful seed germination, which is consequently influenced by various environmental factors such as temperature, salinity and soil moisture. The authors hypothesized that temperature is a determining factor in relation to germination behaviour, affecting seeds’ tolerance to salt. Testing germination response in…
