|
The distal end bears nine very short filaments, each terminating in a bilobed anther. |
|
In the flowers, corolla, corona and anther structure are similar, but the shape of the pollen tetrads in the two genera is different. |
|
This indicates that similar mechanisms may trigger anther dehiscence in rice and two-rowed barley. |
|
Owing to the gradual dehiscence of the thecae, at any time, syrphids could only access part of the pollen of each anther. |
|
The whole perianth was colored, the anther dehiscence was extrorse, the stigma was subulate, and the perianth was hexamerous. |
|
The brush-like hairs at the end of the anther tube are not bent, and they enclose the valve. |
|
In the experiments in Table 1, pricking of an anther and the ovary induced dehiscence whereas cutting or piercing of the glumes did not. |
|
Pollen grain viability at the time of anther dehiscence and later stages was estimated using the fluorescein diacetate test. |

Asexual embryogenesis and plantlet development in anther cultures of Cucumis sativus L. have been reported. |
|
Pollen, in monads or tetrads, is presented in the anthers, adhering to the anther by means of pollenkitt or elastoviscin until collected. |
|
In maize, the stomium is located at the meeting point of the two loculi that make up each half anther. |
|
Flowers were emasculated by removing the anther tube with fine forceps. |
|
The fusion of the corolla lobes to a sympetalous corolla is late taking place by meristem incorporation and fusion across the backs of the anther primordia. |
|
Large fields of green grassland can be seen, one after anther, from which intense green, red and blue roofs stand out, making the scene look a little like fairyland. |
|
The tapetum degenerates earlier than usual, resulting in high pollen sterility, and anther indehiscence occurs when pollen stainability falls below 20 percent. |
|
|
Both species landed directly on the column but, while one scraped its abdomen against the anthers, the other introduced its glossa into the anther, and then scraped it. |
|
When the promoter fragment was resolved into smaller portions, further elements could be identified that conferred root, pulvinus and anther expression. |
|
Lacking an extensive vacuolization phase, meiocytes of the same tetrads stay together until the anther opens and the loculus reduces and disappears. |
|
Each anther has four microsporangia arranged in pairs in the two lobes. |
|
This band of tissue is called the stipe and should not be confused with the caudicles, which are derived from the anther. |
|
Unless otherwise indicated, all observations on the flower should be made at the beginning of anther dehiscence. |
|
The anther of some of the more primitive orchids is superficially similar to that of a lily or amaryllis. |
|
The pollinia are then picked up from the anther and adhere to the body of the insect. |
|
Opening of the anther may be by longitudinal or transverse fissures or by terminal pores. |
|
The majority of the orchids retain only a single anther at the apex of the column. |
|
Soon we will have some in Malaysia and in Kazakhstan, and there's anther one coming up in the United States. |
|
Ordinarily you don't need to give any arguments when starting GIMP, but here is a list of some that may at one time or anther be useful. |
|
There are legal proceedings and forms which change from an establishment to anther. |
|
Large deflector nozzles, anther type of cluster nozzle, spray swaths up to 20 meters wide from a single nozzle. |
|
When expressed in the anther as directed by the specific promoter, this enzyme disrupts pollen development. |
|
Plastid division in the anther is synchronous with cell division, except in the vegetative cell during pollen maturation. |
|
While leaving the flower, it pulls the pollinium out of the anther, as it is connected to the viscidium by the caudicle or stipe. |
|
At the stage of tetrad, the anther wall was composed of epidermis, endothecium and tapetum. |
|
The versatile anther is an important step up in flowering plant evolution and it may be the most widespread of all simple anther types. |
|
In non-heading Chinese cabbage CMS lines, anther development was inhibited at the archesporium cell stage, in which the flower size is smaller than 0.5 mm, and no anther sac was formed to produce normal sporogenous cells. |
|
|
The anther here addresses this challenge by motivating and describing a distinction between reducibly and irreducibly truth-apt sentences. |
|
Anthers, microspores and pollen were analysed in planta from archesporium formation to anther dehiscence, using various cyto-histological techniques. |
|
The single cell layer of tapetum surrounding the anther loculus is first recognizable at the early Microsporocyte stage. |
|
A flight of stairs with a wrought iron handrail delicately curved with scrolls and curlicue foliage leads to the upper level, and anther series of niches with shelves. |
|
A number of ways of exploiting the genetic potential of O. glaberrima are being used, including embryo rescue, anther culture and other genetic engineering techniques. |
|
Should we not have anther section for him? |
|
If you come into the health center anther time, the nurse will fill out another form and give them both a number or a code so that she can keep track of how the telehealth system is used over time. |
|
An anther is adnate when fixed by its whole length to the filament. |
|
At the stage of anther dehiscence, there was one-layer anther wall of endothecium and the tapetal layer was digested completely to nourish the pollen grains. |
|
This occurs when the anther changes from a solid to a liquid state and directly contacts the stigma surface without the aid of any pollinating agent or floral assembly. |
|
The anther of a tomato flower is shaped like a hollow tube, with the pollen produced within the structure, rather than on the surface, as in most species. |
|
However, the species Eulophia foliosa has adaptation in the cap anther that prevents self-pollination by elaterid beetles, favoring crossed pollination. |
|
On maturation of the anther, the sporangial wall consists of the epidermis and the endothecium, whereas the middle layers and tapetum disintegrate. |
|
Anther culture involves the induction of embryoid formation from immature pollen and subsequent regeneration of embryoids into plantlets. |
|
Anther parallel to this is a plan mooted for young men, whereby they may learn woodwork and metalwork skills and thereby sustain themselves. |
