A List of Chromosome Numbers in Angiospermous Plants, III

Methods of Sex Determination in Dioecious Angiospermous Plants

Angiosperms are the most diverse group of land plants which provides fruits, food, seed for cultivation and material for hybridization purpose etc. Approximately 90% of all angiosperm species have hermaphrodite (bisexual) flowers and the remaining, onetenth are either monoecious (male and female flowers are separate but grow in same plant) or dioecious (male and female flower grow on different ...

Chromosome numbers in Chihuahuan Desert Cactaceae. III. Trans-Pecos Texas.

Chromosome numbers are reported for 112 collections of Cactaceae, including 102 collections of Opuntia. Reports are presented for 33 species in five genera and a total of 36 taxa. Two specimens were sterile. Emphasis was given to the documentation of intraspecific ploidy-level consistencies and differences, because of the current poor state of knowledge about the populational integrity of chrom...
