22.2 the, a / an, Ø (zero article) Find the mistakes with the use of the definite article ( the
) and zero article (i.e. no article). Foliar spraying of
copper resulted in an
increase in
copper concentration both in the
leaves and fruits as shown in the
Figure 1. In fact, the
content of
copper in the
leaves increased from 50 mg kg
−1
in the
untreated plants to
100 and 225 m g kg −1 in
plants sprayed with 0.1 and 1 mg Cu, respectively. An
increased copper content following foliar
Cu spraying has been observed in leaves of
several crops such as
cabbage [2,3] and
aubergine [4, 5]. In
literature the effects of Cu on the fruit of
citrus fruit are lacking.
All the examples are correct with the exceptions of
