A broad range of plant selections across the orange subfamily Aurantioideae were screened in solution and soil culture for their tolerance to low iron (Fe) stress. Young seedlings grown in soil were transferred to tubs of +Fe nutrient solution, which was later replaced after a brief period with a –Fe solution. Over several trials, ’20 white root tips were harvested periodically from the plants ...

In this work, seedlings of two citrus rootstocks, the salt-tolerant Cleopatra mandarin (Citrus reshni Hort. ex Tan.) and the salt-sensitive Carrizo citrange (Citrus sinensis [L.] Osb. x Poncirus trifoliata [L.] Raf.) were used to study the relationship between chloride and water uptake. The results indicated that net chloride uptake rates in both genotypes were alike and decreased linearly with...

the production of reactive oxygen species (ros) in plants under low temperature stress cause damage to plants. in order to evaluate of antioxidant responses of page mandarin young trees (two years old) on different rootstocks under low temperatures, an experiment was conducted in a factorial plan based on completely randomized design. treatment of temperatures were at seven levels include 9, 6,...

Drought is among the most crucial limiting factors for crop production and considered a major threat to food security. Rootstock selection an important approach drought management. This research was aimed study responses of rootstocks against stress examine impacts melatonin application on these rootstocks. Carrizo citrange, fying dragon, sour orange were selected current study. To test stress,...

Professor Hume was right: rootstocks are critical and much is still to be learned. Rootstocks and scions are the foundation of many tree fruit industries of the world. Together, those components establish profitability, but it can be argued that the rootstock is the critical component; otherwise, scions would be grown on their own roots everywhere. There is no precedent for the failure of a cit...

Morphological observation of arbuscular mycorrhizal fungi (AMF) species in rhizospheric soil could not accurately reflect the actual AMF colonizing status in roots, while molecular identification of indigenous AMF colonizing citrus rootstocks at present was rare in China. In our study, community of AMF colonizing trifoliate orange (Poncirus trifoliata L. Raf.) and red tangerine (Citrus reticula...

<p>Los portainjertos son clave en la producción de frutales leñosos, ya que influyen precocidad, tolerancia a plagas y enfermedades el vigor las plantas. En INTA EEA Bella Vista hay árboles adultos híbridos se encuentran plena pero aún no han sido evaluados como potenciales para sector citrícola del NEA. El objetivo trabajo fue evaluar parámetros propagación tres cítricos con potencial us...

Seedlings of the hybrid citrus rootstock, Carrizo citrange (Citrus sinensis x Poncirus trifoliata) do not uniformly limit development of the citrus burrowing nematode, Radopholus citrophilus. Variation in nematode population densities in roots of seedlings germinating from the same seed suggests that factors responsible for nematode incompatibility are not functional or are not inherited unifor...

Two-year-old 'Ambersweet' ( Citrus reticulata Blanco X [ C poroc/f'siMacf. X C. reticulata]) X midseason orange, C. s/nensfs(L.) Osb. trees on three rootstocks, sour orange (C. aurantium L), Cleopatra mandarin (C. reticulate), and Carrizo citrange (C. sinensisX Poncirus trifoliate* (L) Raf.) grow ing in 15-liter pots were exposed to cold-hardening regimes in controlled-temperature rooms and fre...
