“…Thus, treated cells have showed difficulties in microtubule and spindle formation. Colchicine has been used successfully in inducing autotetraploid plants in various monocotyledon species, for example, Anthephora ampulacea (Ene-Obong and Mba 1994), Secale cereale (Benavente and Orellana 1991), Sorghum vulgare (Schertz 1962), S. versicolor (Sun et al 1994), and Zea mays (Poggio et al 1990, Molina andGarcia 1999), but their use has not still been reported in succulent plants of the family Aloaceae.…”

Summary Autotetraploid plants of Aloe vera L. were induced by colchicine treatment. Diploid shoot tips (2n =2x=14) were treated by immersion of the rhizomes in colchicine concentrations of 0.05%, 0.10% and 0.15% at exposure times of 6, 12, 18 and 24 h. The highest proportion of polyploid plants (5.9%) with 2n=4x=28 was obtained from a 0.15% colchicine and 24 h combination. Diploid/tetraploid chimerical plants were observed at the lowest colchicine concentration/time treatments. Expression of gigantism in morphological and cytological characters, such as, width and thickness of the leaves, size and frequency of juvenile foliar spots, plant weight, size of epidermal and root cells, were noted in autotetraploid plants with a significant decrease in stomatal frequency.

Chromosome C-banding of the teosinte Zea nicaraguensis and comparison to other Zea species

2007

The Nicaraguan teosinte Zea nicaraguensis was studied cytologically to determine its chromosome number and C-banding pattern. The C-banding pattern was compared with that of the close relative Zea luxurians as well as with Zea diploperennis and cultivated maize, Zea mays ssp. mays. Karyograms were constructed for the four Zea species. It is shown that Z. nicaraguensis, like most other Zea species, is a diploid with 2n=20 chromosomes. The C-banding pattern shows that Z. nicaraguensis is very similar to Z. luxurians and more similar to Z. luxurians than to Z. diploperennis and cultivated maize. Whether or not Z. nicaraguensis and Z. luxurians should be regarded as subspecies instead of individual species is, however, not possible to conclude from this study.
