“…The appearance of ginger flower stems from underground rhizomes at the beginning of the rainy season was similar to that observed in other Zingiberaceae species, which intensify their development with the heat progression during the summer and the constant rains (Parthasarathy et al, 2012;Palupi et al, 2019). The absence of flowering during cooler and drier periods of the year, as seen in the study area, may be attributed to a possible reduction in the species' metabolism, thereby reducing the energy cost for growth and flowering.…”

Ginger (Zingiber spectabile) is cultivated worldwide as a floriculture and landscaping species. Studies on the biology and floral morphology of this species are important for its improvement; however, they are scarce. We investigated the reproductive biology and floral morphology of gingers grown in a germplasm bank. Floral development was monitored during the pre-anthesis and anthesis periods. Floral morphometry, pollen viability, stigmatic receptivity, volume and concentration of nectar sugar, and performance of possible pollinators were evaluated. Ginger flowers had a 24-h durability. Ginger torch is an allogamous species that exhibits floral hercogamy like other Zingiberaceae. Ginger flowers had a 12-h anthesis. During anthesis, floral structures related to reproduction such as the style, stigma, and anther crest continued to develop, increasing floral herkogamy. Pollen viability was above 70% and the stigma remained receptive throughout the anthesis period. Hummingbirds were the only pollinators recorded in the study area that were able to move the anther crest. Fruiting was determined in a natural pollination system. The occurrence of nocturnal anthesis characterized by an increase in the development of reproductive structures and nectar production suggests that the species is adapted to nocturnal visitors.

“…Ginger (Zingiber officinale Rosc. ), 2n=(2x)=22, a monocotyledon belonging to the family Zingiberaceae, is a major spice and medicinal plant that originated in South-East Asia and was later introduced to many parts of the globe (Purseglove et al, 1981;Burkill, 1996;Park and Pizutto, 2002;Parthasarathy et al, 2011). It is a perennial herbaceous but grown as an annual, erect, having many fibrous roots, aerial shoots with leaves and modified underground stem (Ravindran et al, 2005).…”

Ginger (Zingiber officinale) is one of the important and widely used spices throughout the world in fresh and dried forms. The study on quality characterization and essential oil profiling of 13 ginger genotypes was conducted at ICAR-Indian Institute of Spices Research, Kozhikode, Kerala, during 2019-2020. The genotypes included eight promising exotic accessions (Acc. 393, Acc. 607, Acc. 736, Acc. 833, Acc. 869, Acc. 872, Acc. 873 and Acc. 874), four popular cultivars (Nadan, Himachal, Maran, Rio-de-Janeiro) and a released variety IISR Varada. Significant differences among the genotypes were recorded for various quality parameters such as oleoresin, essential oil and crude fibre content. Among the exotic genotypes, Acc. 869 recorded the highest essential oil content (2.44%), followed by Acc. 393 (2.42%), Acc. 833 and Acc. 873 (2.10%). The accessions, Acc. 869, Acc. 874, Acc. 873 and Acc. 393 recorded higher oleoresin content of 5.88 per cent, 5.63 per cent, 5.34 per cent and 5.28 per cent, respectively. Considering essential oil and oleoresin contents, the exotic accessions, Acc. 873, Acc. 393 and Acc. 869 were identified as promising genotypes. Among the other genotypes, Rio-de-Janeiro recorded the highest essential oil (2.76%) and oleoresin content (6.69%). The exotic genotypes, viz., Acc. 607, Acc. 736 and Acc. 393 recorded crude fibre content of less than 5 per cent whereas, Acc. 869 recorded the maximum of 7.85 per cent. Fifty compounds were identified through essential oil profiling, and the major classes were sesquiterpene hydrocarbons followed by monoterpene hydrocarbons. The major compound identified was α-zingiberene and was highest in Acc. 393 (30.49%), followed by Maran (30.32%).

“…Ginger was more valued for its medicinal properties in ancient India and China and played an important role in primary health care. In European medicine also ginger was among the most highly valued of all mild carminatives and it was a component of many pharmaceutical preparations (Purseglove et al 1981;Ravindran et al 2005;Parthasarathy et al 2012).…”

Pollen fertility in 21 germplasm collections of ginger was determined by glycero-carmine staining and in vitro germination. Pollen fertility based on staining ranged from 5.59% to 67.73%, while in vitro germination ranged from 2.35% to 60.31% in different collections analyzed. High pollen stainability was not always followed by high in vitro germination in collections analyzed. However, the in vitro germination percentage was always lower than the percentage of stainability in all the collections. Highest in vitro pollen germination was recorded in acc. no. 195 (60.31%) followed by acc. no. 821 (50.67%). Somatic chromosome number analysis of the collections revealed that the two collections with high pollen fertility (acc. nos. 195 and 821) were tetraploids with 2n = 44 while most of the other collections had 2n = 22, the normal chromosome number. One collection with aneuploid chromosome number of 2n = 24 had lower pollen germination (4.82%), similar to many diploid collections. Tetraploids are identified for the first time from germplasm collections of ginger. The role of polyploidy in improving pollen fertility in ginger is discussed.
