(2019-12-31)
There is a growing demand for high quality seeds to obtain citrus rootstocks. Normative Instruction 48 (MAPA) of September 24, 2013, requires minimum of 50% germination for the marketing of citrus seeds. Harvest season is ...
Aluminum prevents stomatal conductance from responding to vapor pressure deficit in Citrus limonia
(2018-11-01)
Stomatal aperture generally increases in response to low vapor pressure deficit (VPD) and decreases at high VPD. Aluminum (Al) inhibits root growth, indirectly exposing the roots to low water availability, which may decrease ...

(Sociedade Brasileira de Fruticultura, 2008)
A morte súbita dos citros é uma doença que afeta cultivares de laranjas e tangerinas enxertadas nos limões-Cravo e Volkameriano. Ela foi observada em plantas com dois a seis anos de idade que, após mostrarem sintomas gerais ...
Morphogenic gradients of adventitious bud and shoot regeneration in epicotyl explants of Citrus
(Scientia Horticulturae, 2019)
Aluminum-induced high IAA concentration may explain the Al susceptibility in Citrus limonia
(2019-01-15)
In acidic soils (pH < 5.0), aluminum (Al) occurs as Al 3+ , which is phytotoxic and reduces the root growth by hormonal imbalance and/or cell wall rigidity. However, the explanations for the decrease in root growth are not ...

Host status of citrus rootstocks for the population K 5 of Pratylenchus jaehni Pratylenchus jaehni has been reported as the main nematode in Brazilian citrus orchards due to the economic losses it causes. Considering the ...
Caracterização agronômica de frutos e poliembrionia de sementes de porta-enxertos híbridos de citros
(Universidade Federal de São CarlosUFSCarCâmpus ArarasEngenharia Agronômica - EAg-Ar, 2022-04-20)
A good rootstock must add several characteristics such as high number of seeds, polyembryony, resistance to diseases, induction of precocity, among others that are important for citrus production. The objective of this ...
Effects of plant regulators and potassium nitrate, on Rangpur lime seeds germination
(Inst Tecnologia Parana, 1995-01-01)
The effects of plant regulators and potassium nitrate were studied on 'Rangpur' lime (Citrus limonia Osbeck) seeds germination. The seeds were removed from ripe fruits, washed, dried and stored at 4 - 5 degrees C, and ...
