This chapter discusses the various external as well as internal factors that affect the germination of seeds, which are fairly resistant to extreme external conditions, provided they are in a state of desiccation. A variety of factors to which the parent plant is exposed during seed formation and...
Why does the cotyledon become smaller during germination? What are the factors that determine specific soil characteristics? What factors affect the rate of photosynthesis? How does the cotyledon help the seed? What are two advantages of seed plants?
How do earthworms affect soil? What are some factors that influence seed germination? What conditions affect groundwater availability? What factors affect the density of seawater? How does soil affect biome distribution? How does particle size affect the porosity of an aquifer?
a) Light– It is required for thesynthesis of food.It also determines the root and shoots growth. Variations in theintensity, quality,andduration of lightaffectseed germination and flowering in different plants. b) Temperature– A optimum temperature of \(25 – 30^\circ C\) is required for ...
(TFs) that affect the expression of downstream genes. Physiological, genetic mapping, and transcriptomics studies performed with the contrasting genotypes Syn86 (synthetic, salt-susceptible) and Zentos (elite cultivar, salt-tolerant) were integrated to gain a comprehensive understanding of the salt ...
entire distribution area and to speculate on the potential driving factors of the population structure. The purposes of this research are: (1) to determine the level of genetic diversity and population structure ofP. zhennan; and (2) to identify the environmental factors that affect population ...
Cadmium stress affects seed germination and seedling growth in Sorghum bicolor (L.) Moench by changing the activities of hydrolyzing enzymes Seed germination, one of the most important phases in the life cycle of a plant, is highly responsive to existing environment. Hydrolyzing enzymes play a m....
Cold stress is one of the primary environmental factors that affect plant growth and productivity, especially for crops like Brassica napus that live through cold seasons. Till recently, although a number of genes and pathways involved in B. napus cold response have been revealed by independent stu...
How does the tundra biome affect the desert biome? Why are few nutrients available in the tundra biome? What do environmental factors mean in science? What are some factors that influence seed germination? How does soil affect biome distribution?
What are the 20 variables that may affect seed germination? Explain how one specific risk factor may cause an adverse outcome in an adult pregnancy. What is the difference between the replacement fertility rate (RFR) and the total fertility rate (TFR)?
