The Cellular Basis of Rice Seed Growth
Mature rice seed has three major components, the embryo, and nutrient storage tissue endosperm, both belonging to filial generation and seed coat (fused to pericarp) i.e. derived from ovule integuments and bel...

Chapter
Diversity of Panicle Architecture and Traits Influencing Grain Filling
In the long history of domestication through cultivation and selection under diverse habitats; the plant acquired adaptability for growth matching with the physico-chemical behavior of the environment, which i...

Chapter
Hormonal Regulation of Spikelet Development
Many of the identified panicle development genes of the rice plants are homologous to known hormone genes. The class of plant hormones includes both positive and negative growth regulators. In rice, hormone-re...

Chapter
Physiology of Variation in Individual Grain Weight of Rice Panicle
Each spikelet borne on a panicle node is genetically competent to bear a well-developed high- density grain at maturity. But there is a wide margin between the numbers of spikelets differentiated at ontogeny a...

Chapter
Designer Rice in Quest of High Grain Filling
The gain of specific leaf weight (SLW) and leaf area index (LAI) has enabled better light interception through higher radiation use efficiency and the associated increase of SPAD to reduce K values in the newl...

Chapter
Botany of Rice Plant
Cultivated rice Oryza sativa L. is a semi-aquatic annual grass belonging to the family Poaceae of class Monocotyledonae of angiosperm plants. Genus Oryza has another cultivated species, namely, Oryza glaberrima S...

Chapter
Fertilization and Seed Development in Rice
At anthesis, stage spikelets remain open for 30–70 min. The anther box dehisces to release all pollens and become empty. The pollens released reach the feathery stigma. The synchrony between spikelet opening a...

Chapter
Genetic Analyses of Floral Development on Rice Panicle
The relationship of gene activity with morphogenesis of floral organ development in rice is complex. Genetic screening of floral mutants in comparative studies and QTL analyses has been extensively performed t...

Chapter
Enzymes Controlling Starch Biosynthesis
Starch synthesis in a develo** rice grain has been the major factor for grain filling. The physiological constraints that unduly terminate starch synthesis in the inferior type spikelets, and solutes moving ...

Chapter
Change of Panicle Architecture During Domestication
The 12,000 years of rice antiquity embodies evolutionary history beholden with significant changes in panicle architecture. In the process of domestication, rice might have diffused into a gradation of habitat...

Chapter
Effects of Environmental Stresses on Grain Filling of Rice Panicle
Rapid population growth and climate change-induced disturbances in rice agro-ecosystem undermine rice production and accentuate the demand for food. Rice plants demand as much as twice of water consumed by oth...

Chapter
Importance of Rice as Human Food
Rice is the most important grain crop in the world. The worldwide diffusion has established rice as the most important human food. Rice farmers feed and have fed more people than any other important cereal cro...

Chapter
Ontogeny of Organ Development in Rice Plant
During the vegetative stage, the shoot apical meristem of the rice plant repetitively produces leaves as lateral outgrowths. Leaf size varies with its position on the stem axis. Initiation of panicle primordia...
