    Nonequivalent development of adaxial and abaxial tissues gives rise to mature leaf morphology different from that of conventional bifacial leaves (Fig. 4). Abaxialization usually causes a cylindrical leaf type with radialized symmetry, referred to as unifacial (reviewed in Franck, ).Cited by: This book presents the state-of-the-art knowledge on bamboo. It starts with an introduction to the plant’s biology, its taxonomy, habitat, morphology and growth. The cultivation of bamboo is discussed in terms of silviculture, pests and diseases, and harvesting techniques. The book is completed by a comprehensive presentation of the. Larger spikelet clumps and greater wind speed favor larger dispersal d istance s (M cDonald et al., ) Flowering is promoted through external stress es such as cold, mowing, tillage, or burning (Sa jise, ) although some studies suggested flowers produced under such conditions cannot produce viable seed s (Eussen, ).

Cited by: The grasses, and in particular the cereals, have long been investigated as models for studies of chromosome number, morphology, dynamics, and evolution (e.g., Avdulov ; Stebbins ).

The Poaceae are the most important source of the world's dietary energy : Tracheophytes. MORPHOLOGY OF THE RICE PLANT T he cultivated rice plant (Oryza sativa L.) be- longs to the tribe Oryzeae under the sub-family Pooideae in the grass family Gramineae (Poa- ceae).

Biosystematists recently divided the genus Oryza into several sections and placed O. The Gramineae family contains vitally important food plants such as wheat, millet and rice, leading Arber to begin her study with the history of human interaction with these plants.

It was Studies in the anatomy and morphology of spikelet and flower of the Gramineae book first published general description of these important plants, and remains a classic example of. The ancestry and origin of the lodicules, palea, lemma, and glumes have been the subject of a vast and largely inconclusive literature.

Recent work on lodicules in maize and rice has shown that they express petal-identity genes (Ambrose et al., ; Kyozuka et al., ).

Because they are in the position of petals and because the early. Structure of the Flower and Spikelet in Rice Rice belongs to the Poaceae (grass) family, which is widely distributed throughout the world.

Grasses form a complex inflorescence, consisting of a main axis, branches, spikelets and florets (Bortiri & Hake, ; Hirano et al. Belk, E. Studies in the anatomy and morphology of the spikelet and flower of the Gramineae.

The aim has been to see barley literature not only from the viewpoint of the geneticist and cytologist but also from the standpoint of the plant breeder, agronomist and farmer. In a review of Studies in the anatomy and morphology of spikelet and flower of the Gramineae book kind it has been necessary to pass over with only Cited by: Department of Organismic and Evolutionary Biology, Harvard University, Cambridge, Massachusetts We investigated spikelet development in four distantly related species of the grass tribe Andropogoneae to determine whether spikelet development and the formation of unisexual florets are uniform throughout the tribe.

The spikelet proper is a basic unit of a bamboo flower. There is no proper perianth in the floret, being substituted by lodicules.

The origin of lodicules and other bracts (lemma and palea) is. The "moving wall" represents the time period between the last issue available in JSTOR and the most recently published issue of a journal. Moving walls are generally represented in years. In rare instances, a publisher has elected to have a "zero" moving wall, so their current issues are available.

The structure, anatomy and morphology of mature seeds: an overview More general seed structural features: Seeds are the dispersal and propagation units of the Spermatophyta (seed plants): Gymnosperms (conifers and related clades) and Angiosperms (flowering plants).

Each pair of spikelets consists of one pedicel- late spikelet and one sessile spikelet. Each spikelet con- sists of two staminate florets, the upper floret being de- velopmentally in advance of the lower.

Florets consist of two different bracts at the base, the palea and the lemma, and a flower. his studies on the interspecific hybrids, proposed that the basic genomes in Saccharum were x=8 and x= In gramineae, t w o genomes predominate as the basic chromosome numbers, x=7 for the temperate and x=IO for the tropical grasses.

At the base of the spikelet, there is a ring of silky, colorless trichomes (‘coma’) that covers the spikelet (Fig. 3a) and help with spikelet by: Floral morphology remains the cornerstone for plant identification and studies of plant evolution.

A new model for grass functional genomics is described based on Brachypodium distachyon, which in the evolution of the Pooideae diverged just prior to the clade of “core pooid” genera that contain the majority of important temperate cereals and forage grasses.
