“…The fruit characteristics of each pollination combination were investigated at approximately 38 days after fruit development with a ripeness code of 819 [13], including individual fruit weight, fruit transversal diameter, fruit longitudinal diameter, fruit flesh weight, fruit peel weight, edible rate, fruit peel thickness, total soluble solid content (TSSC) in the core of the fruit, and seed weight. The color difference between the sun-exposed and shaded sides of the fruit equator was investigated using a color spectrometer (ColorLite sph860; Katlenburg-Lindau, Germany), and the a* value was used to represent the degree of color change of the fruit.…”

“…"Da Hong" is a major variety of red-fleshed pitaya (H. polyrhizus) cultivated in Taiwan and Southeast Asia with its self-compatibility, large fruit, high yield, and good flavor [6,[11][12][13]. Although its flowering waves are unaffected by high summer temperatures [7], an increase in the proportion of small fruits (<150 g) under high summer temperatures (>35 • C/25 • C) is often observed in open fields or netting facilities [6,7].…”

High summer temperatures (day/night: 40 °C/30 °C) are known to cause poor fruiting, reduced fruit/seed weight, and delayed fruit development in the “Da Hong” red-fleshed pitaya (Hylocereus polyrhizus); however, the mechanisms of these effects are unknown. This study examined how high temperature (HT, 40 °C/30 °C) affects stamen and pistil fertility through pollination combinations and fruit set in “Da Hong” pitaya and evaluated photosystem II (PSII) efficiency in yellowed shoots (cladodes). The in-vitro pollen germination rate was significantly higher at optimal temperature (OT, 30 °C/20 °C) than at HT, which was also associated with a reduced flower length, poor fruit set, small fruit size, and low number of seeds after self-pollination. Meanwhile, fruit set and fruit development were remarkably improved by using the pollens taken from plants grown at OT and moderate temperature (MH, 35 °C/25 °C) after mutual cross pollination, indicating that the reduction in seed number caused by incomplete fertilization due to inferior pollen viability was the main cause of poor fruiting under HT rather than pistil or photoinhibition, although HT treatment was linked to reductions of PSII efficiency at both the adaxial and abaxial ends of shoots. The results suggested that pollen viability was most affected under HT stress; thus, yielding remarkably reduced fruiting.

“…Phenology is the study of repeated events in the life cycles of plants and animals that are very sensitive to climate; as a result, it has received increased attention in the global era of climate change (Kanwar & Sharma, 2023; Zhang et al, 2018). The Biologische Bundesanstalt, Bundessortenamt und Chemische Industrie (BBCH) scale is a system with uniform coding and descriptions of the phenological growth stages of plants (Chu & Chang, 2022; Hernández Delgado et al, 2011; Kishore, 2016). Growth stages are often classified into 10 primary (0–9) and 10 secondary (0–9) growth stages.…”

Sweet potato is grown for its starchy roots in many countries and is widely cultivated in India. This crop is widely acknowledged for its substantial economic and health benefits. However, a comprehensive description of its phenology has not been reported. The phenological growth stages of sweet potato are described here for the first time using the extended Biologische Bundesantalt, Bundessortenamt, and Chemische Industrie (BBCH) scale. Nine primary growth stages have been specifically defined, including germination (0), leaf development (1), main shoot development (2), side shoot development (3), tuber development (4), inflorescence emergence (5), flowering (6), fruit development (7), fruit maturation (8), and senescence (9). The sequential progression of key growth stages has been described according to the phenological development structure and environmental requirements of different phenophases. Because it covers all phenophases related to the vegetative and reproductive stages, the extended BBCH scale is extensively useful for sweet potato cultivation. The extended BBCH scale may also be a useful tool for assessing the potential effects of climate change on crop productivity and fruit quality.
