Abstract
Of 21 species (or varieties or forms) of loquat, Eriobotrya, in China, 17 are being conserved in situ or ex situ.
Among them, 8 species have been reported to be protected in one or more natural reserves.
These species include E. bengalensis Hook.f., E. elliptica Lindl., E. salwinensis Hand-Mazz, E. serrate Vidal in Gaoli-Gongshan or Daweishan, Yunnan; E. cavaleriei Rehd, E. fragrans Champ, E. kwanxinesis Chun, E. japonica Lindl in Nanling, Guangdong, respectively.
The other 9 species, i.e., E. bengalensis forma angustifolia Vidal, E. deflexa Nakai, E. d. var. koshunensis Nakai, E. henryi Nakai, E. malipoensis Kuan, E. obovata W.W.Smith, E. prinoides Rehd and Wils., E. p. var. dadunensis H.Z.Zhang, E. seguinii Card, and E. tengyuehensis W.W.Smith have not been in natural reserves were collected from 6 provinces (Yunnan, Guangxi, Guangdong, Sichuan, Hainan and Taiwan) in southern China.
These 17 collections were placed in ex situ conservation by three propagation methods (seed, seedling and grafting) in the Botanical Garden of South China Agricultural University.
Seedlings had the highest survival rate, which was almost 100% survival.
The success of the other propagation methods depended on the species.
The most successful method of propagation for ex situ germplasm conservation is grafting the scions of mother plant to a rootstock from the same mother plant.
Among them, 8 species have been reported to be protected in one or more natural reserves.
These species include E. bengalensis Hook.f., E. elliptica Lindl., E. salwinensis Hand-Mazz, E. serrate Vidal in Gaoli-Gongshan or Daweishan, Yunnan; E. cavaleriei Rehd, E. fragrans Champ, E. kwanxinesis Chun, E. japonica Lindl in Nanling, Guangdong, respectively.
