changes in chlorophyll florescence is one of the physiological responses of plants to waterlogging stress. due to easily measured in field and its inexpensive and non-destructive characteristics, it is one of the best ways to assess different genotypes tolerance to stresses. in this experiment, trends of chlorophyll fluorescence index (fv/fm) of ‘satsuma’ mandarin (citrus unshiu) on seven roots...

Climate change and global warming are leading to a in weather patterns toward hot cold waves. Citrus fruits tropical or subtropical crop whose growth is altered by changes patterns. Thus, the present work, two experiments evaluated obtain screening method select citrus rootstocks that help us new low-temperature-tolerant plant materials. One experiment was carried out with Poncirus trifoliata m...

Whole-plant hydraulic conductance, shoot growth, and leaf photosynthetic properties were measured on kiwifruit vines with four clonal rootstocks to examine the relationship between plant hydraulic conductance and leaf stomatal conductance (gs) and to test the hypothesis that reduced hydraulic conductance can provide an explanation for reductions in plant vigour caused by rootstocks. The rootsto...

Three-year-old citrus trees were grown in the greenhouse to study the effects of fertilizer concentration and root herbivory on plant growth and mineral concentration. In separate experiments, sour orange (Citrus aurantium L.) and Swingle citrumelo (C. paradisi Macf. Poncirus trifoliate L.) plants were treated with a complete fertilizer diluted to provide 25, 100, 200, or 400 ppm N and grown fo...

The aim of this study was to determine organic acids and individual sugars as well as carotenoids in fruit of Kumquat[Fortunella margarita (Lour.) Swingle] on different rootstocks.  On other hand, the purpose of this study was to identify the rootstock that could produce the highest amount of sugars. The content of individual sugars and organic acids in fruits were determined by HPLC, ...

Citrus relatives are a relevant source of valuable traits for use in citrus breeding, including resistance to diseases such as Huanglongbing (HLB). Resistant rootstocks may impact tree responses HLB. This requires graft compatibility, which has been poorly investigated within the Aurantioideae. In this study, biometric characteristics and anatomy union 86 scion/rootstock combinations were asses...
