Introduction Wheat (Triticum sp.), an extensively adapted crop, is one of the primitive and primary staple food crops in the world. Wheat is cultivated from temperate; dry to irrigated or rain-fed areas, to warm, humid or cold conditions. Such a high adaptability is attributed to its intricate genome (Acevedo et al., 2002). Wheat cultivation covers more land area compared to other commercial crops and endures to be an essential food grain for humans (Curtis, 2002). Estimations reveal that by 2050, the population of the world will reach 9.1 billion (34 percent greater than today); correspondingly, the food requirement and ...

ABSTRACT

Spring-time events such as flowers budding have advanced by two and a half days per decade since the 1970s in Prairie regions (Korner C, Science, 2010).The flowering of a plant is a central event in its life-cycle, especially in plants growing in temperate regions of the world. These events are known as phenological changes and phenology is the study of plant and animal life-cycles in relation to annual and seasonal climate variations. Flowering phenology combines various diverse fields of study such as plant physiology, climatology, historical studies, and botany (Tooke F, J of Exp. Biology, 2010). The break of dormancy ...

Discussion of the Dynamics of Endoplasmic Reticulum And Mitochondria

Introduction The Endoplasmic Reticulum (ER) of an organism forms an interconnected membrane network that extends from the outermost nuclear to the periphery cell wall. Mitochondria are a group of cell organelles that undergo fusion and fission at a constant rate. . In plants, daily regulation of energy is important for optimal growth thus mitochondria are important for integral regulation of the cellular responses for the survival of the plant. . In this paper, we are going to discuss the dynamics of ER and the mitochondria in plants by looking at the importance of Lat.B, AA and MV regulation energy in treated and ...

Biology Lab Report

Abstract Plant damage by herbiovry needs to be studied especially with potential negative impacts from climate change. The impact of caterpillars on cucumber leaves was measured under three different situations. Firstly when the leaves were damaged with holes, secondly when saliva was added or thirdly when leaves were both damaged and saliva was added. The hypothesis tested was ‘There will be an increase herbiovry on damaged and saliva treated plants compared to saliva and no damaged or damage and no saliva treated plants. The leaves were photographed before treatment and after, caterpillars were added to the leaves under ...
