“…This phenomenon suggested that other abiotic or biotic environment factors, such as population density or intraspecific competition, could also affect the morphological development of flowers. For example, studies have reported that population density could affect plant reproductive outputs and survival by increasing resource competition (Knight, ; Oleques & de Avila, ), and plants in high‐density populations have fewer ovules per flower and smaller inflorescences (Weber & Kolb, ). At the same experimental sites, our previous work showed that P .…”

Relationships between sex‐specific floral traits and endogenous phytohormones associated with altitude are unknown particularly in dioecious trees. We thus examined the relationships between floral morphology or biomass and phytohormones in male and female flowers of dioecious Populus cathayana populations along an altitudinal gradient (1,500, 1,600, and 1,700 m above sea level) in the Xiaowutai Nature Reserve in northern China. The female and male flowers had the most stigma and pollen at 1,700 m, the largest ovaries and least pollen at 1,500 m, and the smallest ovaries and greater numbers of anthers at 1,600 m altitude. The single‐flower biomass was significantly greater in males than in females at 1,600 or 1,700 m, but the opposite was true at 1,500 m altitude. The biomass percentages were significantly higher in anthers than in stigmas at each altitude, while significantly greater gibberellin A3 (GA 3), zeatin riboside (ZR), indoleacetic acid (IAA), and abscisic acid (ABA) concentrations were found in female than in male flowers. Moreover, most flower morphological traits positively correlated with IAA in females but not in males. The biomass of a single flower was significantly positively correlated with ABA or IAA in males but negatively with ZR in females and was not correlated with GA 3 in both females and males. Our results demonstrate a distinct sexual adaptation between male and female flowers and that phytohormones are closely related to the size, shape, and biomass allocation in the pollination or fertilization organs of dioecious plants, although with variations in altitude.

“…At present, scholars about N. alata at home and abroad had focused on the expression pattern analysis of essential genes 1,28,29 , cultivation management [30][31][32][33] and characteristics of fertilizer requirements, selfincompatibility mechanism and regeneration system 29,34−36 , etc. No research has been done on the distribution and growing areas of N. alata. Here, in order to provide a reference for the planting of N. alata, MaxEnt ecological niche model was used to predict the range of suitable planting areas for N. alata under current and future climate conditions.…”

Nicotiana alata Link et Otto, widely used in landscaping, is not only of great ornamental value but also of high commercial and medical value. The global potential habitat of N. alata and the environmental factors affecting its distribution are not that clear at present. To provide a reference for the reasonable and extensive planting of N. alata now and in the future, MaxEnt model was used to predict its global suitable habitats under current and future climate conditions, respectively, based on global geographic distribution data of N. alata and the current and future world bioclimatic variables. The results showed that mean annual temperature (bio1), annual precipitation (bio12), temperature seasonality (bio4), and mean temperature of driest quarter (bio9) were the key bioclimatic variables governing the distribution of N. alata. The global suitable habitats of N. alata were mainly distributed in Europe, the United States, Mexico, southeastern South America, and southern Africa under current climate conditions. Compared with current climate conditions, the future climate decreased suitable habitats of N. alata under SSP1-2.6 scenario and increased suitable habitats of N. alata under SSP2-4.5, SSP3-7.0 and SSP5-8.5 climatic scenarios. The results provided valuable information and theoretical reference for the reasonable planting of N. alata.

The global suitable habitats of N. alata were mainly distributed in Europe, the United States, southeastern South America, and China under current climate conditions. Compared with current climate conditions, the future climate decreased suitable habitats of N. alata under SSP1-2.6, and SSP2-4.5 scenario and increased suitable habitats of N. alata under SSP3-7.0, and SSP5-8.5 climatic scenarios.
