Treatment B was conducted to examine autonomous self-pollination by enclosing intact flowers, before anthesis, in small plastic bags. |
|
Seeds were collected from these two rows of the flower head only and at defined days after anthesis. |
|
The main culms of the plants were harvested at anthesis, 18 days post-anthesis and at maturity. |
|
However, at anthesis they appear one above the other, because in one ovule the funicle greatly elongates. |
|
On each individual, three flowers were emasculated before anthesis and isolated using silk bags, while the fourth was taken as the pollen donor. |
|
In developing flowers the stamens are tightly appressed but soon mature centripetally and bend extrorsely at anthesis. |
|
In an individual flower, anthesis starts at the end of the day and by the time the bats start feeding, there is copious pollen. |
|
In principal, the length of flower anthesis depends on pollination and removal of the pollinium. |
|
Anthers were isolated from flowers at anthesis and pollen grains were collected. |
|
On the day of anthesis, unopened flowers and flowers that had opened on previous days were removed from each branch. |
|
Unpollinated ovaries were prepared by bagging the female flowers before anthesis. |
|
Only the outermost two or three cell layers and the inner epidermis remain compact at anthesis. |
|
Perfect flowers are protandrous, hence the stigmas open after anthesis, which reduces the probability of autogamous self-pollination. |
|
For example, the weakly zygomorphic flower is scarlet, shows diurnal anthesis and has a backwardly curved labellum. |
|
The antipodal cells are much smaller than the other cells of the gametophyte and typically persist beyond anthesis. |
|
During anthesis, petals gradually lose their colour, becoming completely white or pale lilac by the end of anthesis. |
|
As the ovary elongates only above the placenta, the ovules appear basal at anthesis. |
|
As the flowers are proterogynous anthesis was considered to comprise the period between bud opening and the abscission of stamens and nectaries. |
|
At the anthesis, a nectary is present at the base of the ovary and trichomes can be observed on the ovary epidermis. |
|
During anthesis, the standard petal curves backward after the expansion of the wing petals. |
|
|
First anthesis was reached when stamens became visible on the outer ring of flowers on the capitulum. |
|
In the same panicle, anthesis occurs from the middle position toward both apical and basal ends. |
|
However, position of the flower within the panicle correlated with time of anthesis and gender. |
|
At the time of anthesis, 80 flowers growing on 16 terminal cladodes were marked for growth measurements. |
|
Although a higher proportion of fruitlets were thinned from the low-vigour vines after anthesis, these vines still carried higher crop loads relative to total leaf area. |
|
In place of these, we analyzed timing of anthesis, presence or absence of seed wings and pistillate racemes, and prevalence of acuminate leaf apices and attenuate leaf bases. |
|
The reddish colour of the depistillated flower and its peduncle is a response to high light intensities during anthesis and should not be interpreted to indicate senescence. |
|
The ovary of macadamia contains two orthotropous ovules at anthesis. |
|
Releasing pollen, the flowers are in anthesis, which has garnered the attention of red-necked blister beetles. |
|
Part of the anthesis takes place while the flower is still closed, thus indicating that the Maca flowers are partially cleistogamous. |
|
The number of flowers per axil should be observed on the middle third of the plant on the flower bud, before anthesis. |
|
Each flower, surrounded by a thin membraneous sheath, topped a short pedicel that elongated during the last stages of flower development up to anthesis. |
|
The results show that early fertilization leads to the formation of apomictic embryos while fertilization at anthesis favours the formation of sexually derived embryos. |
|
In both experiments, flowers on racemes from main stem nodes in the middle of the canopy were tagged before anthesis and their development and growth were monitored. |
|
In the field the plants displayed many flowers at full anthesis. |
|
In taking steps to avoid plant stress, for example the use of irrigation, steps should be taken to minimise the subsequent risk of fungal infection, e.g. by avoiding spray irrigation during anthesis. |
|
Adults of F. occidentalis appeared at the beginning of flowering and population decreased towards completion of anthesis, and they damaged kernels. |
|
The flowers are densely distichously arranged on the branches, but clearly move apart after anthesis. |
|
The xylem of anthesis flower parts and pedicels consists exclusively of tracheary elements with helical bands, and rarely, with annular bands. |
|
Ribulose bisphosphate carboxylase and proteolytic activity in wheat leaves from anthesis through senescence. |
|
|
Total titratable acidity of annual ryegrass silage made with anthesis stage ryegrass was only one tenth of the acidity of booting or heading stage. |
|
Flowers distichous, anthesis nocturnal, with an odor, strongly downwardly secund at anthesis, densely to subdensely arranged, 65-70 mm long, pedicels stout, 6-11 mm long, ca. |
