摘要：Micrografting provides cloned plants, which are also largely free from pathogens, including viruses andvirus-like pathogens. Though micrografting is a tedious and time consuming technique requiring also exceptivedexterity, it provides a practicable method, whereby very minute shoot meristems (less than 1 mm in length) can beregenerated even in those plant species where such small excised shoot meristems cannot be regenerated as has beenthe case in Citrus. Micrografting has been most extensively and usefully applied to Citrus amongst all the fruit trees.The most glaring example of improvement of citrus orchards leading to many-fold increase in fruit production has beendemonstrated in Spain by producing about 31 million healthy plants originally recovered by micrografting. Despite thefact that shoot meristems of all the scion species, viz., C. sinensis, C. aurantifolia, C. reticulata and C. nobilis x C.deliciosa could be regenerated and proliferated without the support of rootstock seedlings already having developedroot systems, it had been necessary to see the performance of micrografted shoot meristems of these species, using 3important citrus rootstocks, namely, C. limonia, C. karna and C. jambhiri. Except C. aurantifolia, which could beprofitably grown on its own root system under field conditions, rest of the scion species required rootstocks for their exvitro survival and flourish in order to be productive.
