Among the interesting articles we invite you to find news about the allelopathic potential of leaf extracts from Dischidia imbricate; quinoa (Chenopodium quinoa) growth in response to fertilization and soil tillage; drought avoidance and phenotypic flexibility of sweet potato (Ipomoea batatas) under water scarcity conditions; development of an efficient ‘one-step freezing’ cryopreservation protocol for a Georgian provenance of chestnut (Castanea sativa) zygotic embryos; effect of nitrogen fertiliser and lime on the floristic composition, soil microbes and dry matter yield of Danthonietum calycinae grassland; screening for salt and water stress tolerance in fir (Abies alba) populations; somatic embryogenesis induction in leaf and root explants of Allophylus edulis; spatial distribution of glomalin-related soil proteins in coniferous and broadleaf mixed temperate forest etc. Notulae Botanicae Horti Agrobotanici Cluj-Napoca journal has moved to online-only publication at the start of 2017; beginning in 2019, the journal appears quarterly.
