Abstract:
... Olive cultivation tends to adopt new planting density and pruning systems in domestic olive types in Turkey. The effect of different planting densities and pruning types on the changes of some endogenous plant hormones in shoot tips and flowering in ‘Gemlik’ olive cultivar was studied. The two-year-old seedlings were planted at 5 × 5 m, 4 × 3 m and 4 × 1.5 m densities, and were pruned as either op ...

Abstract:
... Sucrose accumulation curves represent the maturity profile of sugarcane cultivars, which is considered as a character of interest for the selection of genotypes in breeding programs. However, variations due to the environment (E) and interaction between genotype and environment (G × E) may be confused with the effect of genotype (G) and hinder the selection process of promising clones. The objecti ...

Abstract:
... The family Orchidaceae, with over 25,000 species, includes five subfamilies and nearly 700 genera. Loss of plants in the wild has resulted from clearing of forests and excessive collection for various purposes. Moreover, the requirement of symbiotic association during seed germination under natural conditions adds a certain level of difficulty in retaining the orchid resources in the wild. Cryopre ...

Abstract:
... Plants can be regenerated from various explants/tissues via de novo shoot meristem formation. Most of these regeneration pathways are indirect and involve callus formation. Besides plant hormones, the role of polyamines (PAs) has been implicated in these processes. Interestingly, the lateral root primordia (LRPs) of Arabidopsis can be directly converted to shoot meristems by exogenous cytokinin ap ...
