Many species of plants have the sex organs in different flowers on the saae tree or even on different trees (Fig. In this type of inflorescence, you can see the peduncle modified in narrow cup-like structure. var gaJsHost = (("https:" == document.location.protocol) ?

Variations may have been due to the differences in the number of flowers produced by the trees. winter drought stress, flower induction, leafy inflorescence, fruit number, citrus: DOI: 10.17660/ActaHortic.2014.1058.45: Abstract: Leafy inflorescences in citrus have been reported to favor higher fruit set and fruit persistence than leafless inflorescences. AND INFLORESCENCE The citrus flower is perfect; i.e., it has both female and male sex organs in the same flower. Three plants from each of Terminals on which the earlier flowers appeared tended to have more inflorescences than those on which flowers appeared later. The sequence of anthesis on an inflorescence was: apical flower first, then basal flower, then the subapical flower. Raceme Inflorescence… Inflorescence type has been modified not only during the induction period, but also in initial flower shoot development phases [91,92]. Our online platform, Wiley Online Library ( is one of the world’s most extensive multidisciplinary collections of online resources, covering life, health, social and physical sciences, and humanities. For terms and use, please refer to our Terms and Conditions Stem: Woody (Citrus, Feronia), erect, cylindrical, branched, solid often thorny (Citrus), gland dotted. Fig. Inflorescences that began flowering later were more likely to have leaves or have a greater number of leaves than earlier inflorescences. These patterns generally differed little from year to year. However, only data on inflorescence development and fruit-set pat- In subtropical humid climates like Florida, drought stress during winter may be used as a management strategy to delay flowering in late-season sweet orange cultivars destined for late-season mechanical harvesting to avoid the loss of young fruit from next year’s crop. They are usually stalked, and borne in a basipetal (growing downward towards the base or from the point of attachment) order. All three types of flowers are present in this inflorescence. Citrus is the most important fruit crop of the world and production of fresh and processed citrus surpasses that of banana, apple, grapes or ... Inflorescence type Inflorescence are flowering shoots arising from axillary buds. Racemose is a type of an inflorescence where the main axis continues to grow indefinitely and does not terminate in flower. This web page accompanies a textbook. The main characteristics are: Growth of the main axis (peduncle) is indefinite and continues to produce a … JSTOR is part of ITHAKA, a not-for-profit organization helping the academic community use digital technologies to preserve the scholarly record and to advance research and teaching in sustainable ways. IN CITRUS flower initiation occurs shortly before the development of the inflorescence begins (Ab-bott, 1935). Extreme water stress reduces flowering, and GA content became significantly higher in the leaves of trees under severe water stress than in the leaves of trees that endured moderate water stress [101,102]. pageTracker._initData(); JSTOR®, the JSTOR logo, JPASS®, Artstor®, Reveal Digital™ and ITHAKA® are registered trademarks of ITHAKA. AJB publishes peer-reviewed, innovative, significant research of interest to a wide audience of scientists in all areas of plant biology (e.g., biodiversity, structure, function, development, genetics, evolution, reproduction, systematics), all levels of organization (molecular to ecosystem), and all plant groups and allied organisms (cyanobacteria, algae, fungi, and lichens). Leaves: Alternate (Citrus, Murraya) or opposite (Evodia), petiolate, petiole may be winged (Citrus aurantium), simple or compound-pinnate (Murraya), palmate (Aegle and Citrus) smooth gland dotted, glands with essential oils, exstipulate, margin entire or serrate, unicostate reticulate venation. Citrus flowering: Citrus species show a relatively long juvenility period (two to five years) before the trees reach the mature stage to produce flowers. Select the purchase : "http://www. This variation includes a range from one to several flowers with as many as 19 flowers "https://ssl." This proximity in timing between flower initiation and shoot growth may help ex-plain the variation in inflorescence structure that develops. The inflorescence developed in citrus may be either leafless or leafy and these may carry a single flower or several of them (Goldschmidt and Huberman, 1974… 2. The fruit is pleasantly fragrant, thick-skinned, with a short neck and a conspicuous nipple. Patterns on Marsh grapefruit resembled those for the oranges but were frequently less consistent. © 1973 Wiley Question: Write a note on Mixed Inflorescence.
