“…Thus flowering dynamics in chia is almost completely determined by the interaction of day length and photoperiod (data not shown), and not by the number of vegetative nodes as in Chrysanthemum (Mattson and Erwin, 2005), a short day plant in which flowering is also determined by a critical number of vegetative phytomers (Jensen et al, 2013).…”

2900 kg ha-1) and oil production (> 550 L ha-1). In Las Cruces (LC), at higher latitude, low temperatures present beginning in April coincided with the reproductive stage, affecting yield which was no more than 129 kg ha-1; thus this zone is not recommendable for chia cultivation. This study also determined an 11.8 h day length threshold for the beginning of flowering; when plants are exposed to shorter days flower initiation is more precocious, but when day length is not adequate plants only begin to flower when they have accumulated 600-700 °C d.]]>

“…exserta is a facultative short-day species, with a critical day-length of 11.5 h. Previous reports have shown that the photoperiodic response is variable among Salvia species. For example, S. elegans and S. gregii are obligate and facultative short-day plants, respectively; but S. patens and S. farinacea are both facultative long-dayplants (Mattson and Erwin, 2005;Zanin and Erwin, 2006).…”

“…In ornamental plants, for example, the photoperiod impacted the mean dry weight gain of more than 75% of 41 species, principally those grown under LD (Mattson and Erwin, 2005). However, for five populations of the tropical tree Hymenaea courbaryl, originated from regions between nearly 20°N and 2°S, LD affected all the plants similarly, despite their origin.…”

Caesalpinia echinata Lam. (brazilwood) is an endangered tree species occurring along the eastern coast of Brazil from latitudes 5°56´S to 22°56´S. With such a range of distribution it is expected that temperature and daylength may affect plant development, which was examined in this study. One-and five-year-old saplings were grown under controlled photoperiods of 8 h, 12 h and 20 h, and in a greenhouse under natural light during 16 months. In another experiment, oneyear-old saplings were cultivated for six months in a growth cabinet, with reduced maximum temperature, and in the greenhouse. Leaf number, stem height and stem diameter at the soil surface were evaluated every two months (experiment 1) or every month (experiment 2). In experiment 1, no significant effect of photoperiod on growth of saplings was observed. The increase of leaf number with time followed a polynomial model, and the slope of the curves differed significantly for saplings of the two ages. Stem height increased linearly in younger saplings and fitted a polynomial curve in older saplings. Stem diameter enlarged linearly with time in all saplings. Growth parameters were significantly related to high temperatures. In experiment 2, significant regressions between growth and the maximum daily temperatures recorded were also found for increase of leaf number and stem height increment. Our results show that vegetative growth of the saplings of this tropical species is affected by temperature but not by photoperiod.

(pau-brasil) é uma espécie arbórea ameaçada, que ocorre na costa leste do Brasil, em latitudes de 5°56´S a 22°56´S. Em tal faixa de distribuição espera-se que a temperatura e o comprimento do dia possam afetar o desenvolvimento da planta, o que foi investigado no presente estudo. Plantas jovens com um e cinco anos de idade foram cultivadas sob fotoperíodos controlados de 8 h, 12 h e 20 h e em casa de vegetação, sob luz natural, durante 16 meses. Em outro experimento, plantas jovens com um ano de idade foram cultivadas por seis meses em câmara de crescimento, onde a temperatura máxima foi reduzida, e em casa de vegetação. O número de folhas, a altura do caule e o diâmetro do caule à superfície do solo foram avaliados a cada dois meses (experimento 1), ou mensalmente (experimento 2). No experimento 1, não foi encontrada alteração de crescimento nas plantas crescendo sob os diferentes tratamentos fotoperiódicos. Foi possível ajustar regressão polinomial para o aumento do número de folhas, em função do tempo, com diferença significativa na inclinação da curva para as plantas das duas idades. A altura do caule aumentou linearmente nas plantas mais jovens e, nas mais velhas, tal parâmetro ajustou-se à regressão polin...
