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...
What factors contribute to the number and size of plant stomata? 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?
Some biological characteristics that foster the invasion of Prosopis juliflora (Sw.) DC. at Middle Awash Rift Valley Area, north-eastern Ethiopia A study on some biological features of (卤307S.E.). Germination of seeds of P. juliflora differed significantly among the various treatments. The ...
Stress due to chilling/freezing usually occurs in the early growth stages and can cause slow germination, developmental delays, and even plant death. The occurrence of cold stress at the early reproductive stage (mostly caused by CDWI) can adversely affect yield and grain quality [8, 9]. In...
Light quality did not affect final germination percentage. The seeds tolerated drought of up to –0.8 MPa polyethylene glycol. The tolerance of B. hybridum seeds produced at higher thermoperiods to moderate levels of osmotic stress and their higher dormancy indicate that this species has the ...
Several environmental factors affect seed germination (Chauhan, B.S., et al., 2006, Mennan, H. and Ngouajio, M., 2006). Seeds of camel melon (Citrullus lanatus (Thunb.)), colocynth (Citrullus colocynthis (L.) Schrad.), and prickly paddy melon (Cucumis myriocarpus L.) are invasive...
that the interplay of calcium-binding proteins, WRKY, and AP2/ERF TF families in signaling pathways at the start of the osmotic phase can affect the expression of downstream genes. The identification of SNPs in promoter sequences and 3ʹ -UTR regions provides insights into the molecular ...
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...

Their feeding on ripe fruits is also seen as a natural method of pest and diseases control by getting rid of fruits that may harbor insect pests or disease pathogens. Many animals, including birds, hasten germination as seeds pass through their intestinal tracks. ...
