The pineapple [2] [3] (Ananas comosus) is a tropical plant with an edible fruit; it is the most economically significant plant in the family Bromeliaceae. [ 4 ] The pineapple is indigenous to South America , where it has been cultivated for many centuries.
Cold-hardy citrus is citrus with increased frost tolerance and which may be cultivated far beyond traditional citrus growing regions. Citrus species and citrus hybrids typically described as cold-hardy generally display an ability to withstand wintertime temperatures below −5 to −10 °C (23 to 14 °F).
The pineapple is an example of a CAM plant.. Crassulacean acid metabolism, also known as CAM photosynthesis, is a carbon fixation pathway that evolved in some plants as an adaptation to arid conditions [1] that allows a plant to photosynthesize during the day, but only exchange gases at night.
Schematic of typical plant cell. When temperature drops, the membrane fluidity, RNA and DNA stability, and enzyme activity change. These, in turn, affect transcription, translation, intermediate metabolism, and photosynthesis, leading to an energy imbalance. This energy imbalance is thought to be one of the ways the plant detects low temperature.
H1a, higher than 15 °C (59 °F), applies to tropical plants permanently under glass in heat; while H7, below −20 °C (−4 °F), applies to very cold-tolerant plants such as heathers. Most outdoor plants in the UK fall within the range H4, −10 to −5 °C (14 to 23 °F) (hardy in the average winter) to H5, −15 to −10 °C (5 to 14 °F ...
Eucomis comosa is an ornamental plant with numerous cultivars, varying in colour from forms with white flowers and little or no purple on the leaves, to forms with deeply coloured leaves. Described as "surprisingly hardy" in the UK, [ 3 ] down to −5 or −10 °C (23 or 14 °F), [ 3 ] [ 4 ] it needs a sheltered spot in full sun, and a ...
HSFs are essential in plants’ ability to both sense and respond to stress. [5] The HSFs, which are divided into three families (A, B, and C), encode the expression of heat shock proteins ( HSP ). Past studies have found that transcriptional activators HsfA1 and HsfB1 are the main positive regulators of heat stress response genes in ...
A xerophyte (from Greek ξηρός xeros 'dry' + φυτόν phuton 'plant') is a species of plant that has adaptations to survive in an environment with little liquid water. Examples of xerophytes include cacti, pineapple and some gymnosperm plants. The morphology and physiology of xerophytes are adapted to conserve water during dry periods.
