Theovuleof an angiosperm is contained within the ovary of the pistil. The ovule plays a crucial role in flower reproduction. It is the organ within the plant that produces and houses egg cells. After fertilization, the ovule becomes the fruit, seed, or seeds of the plant. The ovule consist...
because of potential position effects on ovule number and seed-set. Mature fruit were collected individually and the contents classified and counted as described above.

During floral development, the calyces of the terminal flower and of one of the lateral flowers often fuse, forming a compound fruit structure. CONCLUSIONS: In Beta vulgaris, the inflorescence is compound, consisting of an indeterminate main axis with many elementary dichasia as inflorescence units,...
Is a blueberry an aggregate fruit? Moreover, to be a berry, fruits must develop from one flower that has one ovary, Jernstedt said. Some plants, such as the blueberry, have flowers with just one ovary. Hence, theblueberry is a true berry, she said. ... Because these types of frui...
This is an inherent limitation of the study system because male reproductive structures are usually lacking when sporophytes mature, which prohibits sexing of sterile male shoots. Therefore, we do not know whether the skew in paternity mirrors male genotype abundances in the population or differences...
