Vegetative characters of Agave landraces used for the production of pulque in Tlalcuapan, Chiautempan, Tlaxcala
<p>Raw data of 32 morphological variables of vegetative characters of three Agave landraces (N=61 individuals) used for the production of pulque in San Pedro Tlalcuapan locality of Tlaxcala state. <br> The landraces used for pulque production of Agave salmiana ´Manso’, ‘Prieto’ and ‘Amarillo’ were identified at the species and subspecies level following García-Mendoza’s (2011) and Gentry’s (1982) taxonomic keys. Thirthy two morphological variables were measured in de field during 2018. These data were used to analyze and describe the morphological and traditional diversity of these varieties.<br> </p>
Effects of experimental warming on vegetative and reproductive characters of P. viviparaum in the Qinghai-Tibet Plateau
<p>This dataset contains data from a simulated warming experiment described in the paper: "Zhang, C., Li, XT., and An, YM. Effects of experimental warming on vegetative and reproductive growth of <em>Polygonum viviparaum</em> in the Qinghai-Tibet Plateau. Nordic Journal of Botany. DOI: 10.1111/njb.03157". </p> <p>The experiment investigated <i>Polygonum viviparaum</i>, a perennial herb distributed widely in arctic and alpine regions, under two different levels of experimental warming treatments to examine effects of warming on its vegetative and reproductive growth. Two types of open top chambers (OTCs), large and small, were used to generate lower and higher warming levels.</p> <p>The dataset consists of the vegetative and reproductive characters of <i>P. viviparaum</i> in control plots, large OTCs and small OTCs. The characters include plant height, leaf number, length of the longest leaf, flower diameter, bulbil length, number of flowers per spike, number of bulbils per spike, flower proportion, dry weight of stem and leaves, dry weight of flowers per spike, dry weight of bulbils per spike, reproductive allocation and bulbil germination rate.</p> <p>Main results of the experiment are that (1) the increased temperature promoted both vegetative and reproductive growth of <em>P. viviparaum</em>, but there was a significant trade-off between them. Decreased reproductive allocation under warming suggested that more available resources were devoted to vegetative growth, resulting in increased plant height, leaf number and length of the longest leaf; (2) After warming, the number and dry weight of flowers per spike decreased while the number and dry weight of bulbils per spike increased, indicating more investment to asexual reproduction over sexual reproduction in <em>P. viviparaum</em>; (3) The increase of warming further strengthened the above variation trends of vegetative and reproductive growth of <em>P. viviparaum</em>.</p>

FIGURE 2 in Kalanchoe ×sampsonii [K. ×hankeyi × K. sexangularis] (Crassulaceae subfam. Kalanchooideae), a horticulturally successful nothospecies from South Africa with enhanced vegetative and reproductive characters
FIGURE 2. Kalanchoe ×sampsonii. A. At flowering maturity plants of this shrubby nothospecies reach a height of about 0.5 m. B. Through heterosis, inflorescences are more branched and have a wider spread than in either of the parents. C. Peduncles are more intensely reddish-infused than in K. ×hankeyi, but less than in K. sexangularis. D. Flowers (corolla tube and corolla lobes) are more intensely yellow than those of either of the parents. E. Flowers, here in lateral view, of K. ×sampsonii (centre) are often intermediate between those of K. longiflora (left, one of the parents of K. ×hankeyi) and K. sexangularis (right), but the corolla tube is more intensely yellow. F. Corolla lobes of K. ×sampsonii (centre) are more intensely yellow than those of K. longiflora (left, one of the parents of K. ×hankeyi) and K. sexangularis (right, the other parent of K. ×hankeyi). G. A White-bellied sunbird, Cinnyris talatala, feeding on the copiously nectariferous flowers of K. ×sampsonii. H. Jason D.S. Sampson (1979–), after whom K. ×sampsonii is named, next to a very large specimen of K. ×estrelae on the Hatfield campus of the University of Pretoria; photograph taken on 10 June 2022.

FIGURE 1 in Kalanchoe ×sampsonii [K. ×hankeyi × K. sexangularis] (Crassulaceae subfam. Kalanchooideae), a horticulturally successful nothospecies from South Africa with enhanced vegetative and reproductive characters
FIGURE 1. Kalanchoe ×hankeyi (A–B) and K. sexangularis (C–D). A. Leaves of K. ×hankeyi are light green to strongly red-infused, especially when grown in full sun. The marginal leaf crenations of K. ×hankeyi are situated more towards the upper parts of the leaf margins, as in one of its parents, K. longiflora, rather than virtually along the whole margin, as is found in the other parent, K. sexangularis. B. Flowers of K. ×hankeyi have yellow corolla lobes and a greenish yellow tube. C. Leaves of K. sexangularis turn a bright crimson red when exposed to high levels of solar irradiation. D. As in the case of K. ×hankeyi, flowers of K. sexangularis have a greenish yellow corolla tube and yellow corolla lobes. All photographs taken by Gideon F. Smith.

Vegetative characters of Agave landraces used for the production of pulque in Tlaxcala.
<p>Raw data of 19 morphological variables of vegetative characters of nine Agave landraces (N=478 individuals) used for the production of pulque in 10 localities of Tlaxcala. These data were used to analyze and describe the morphological diversity of these varieties.</p> <p>Nine <em>Agave</em> landraces used for pulque production in 10 localities Tlaxcala were analyzed: <em>Agave salmiana</em> subsp. <em>salmiana</em> ‘Amarillo’, ‘Ayoteco’, ‘Colorado’, ‘Chalqueño’, ‘Chino’, ‘Manso’, ‘Prieto’, and ‘Xilomelt’ and <em>Agave mapisaga</em> var. <em>mapisaga</em> ‘Palmilla’. Twenty-two populations of 13–35 individuals were included in the study (N = 478 individuals). Both landraces and wild individuals were identified at the species and subspecies level following García-Mendoza’s (2011) and Gentry’s (1982) taxonomic keys. Twenty morphological variables were measured in de field between 2018 and 2019.</p> <p> </p>
