Figure 2. Effects of EM-calcium application on some routine indexes of tomato quality. Columns with the same letter
represent values that are not significantly different at the 0.05 level of probability according to the Duncan's multiple
range test. Each value is the mean ± SD (n=3). The treatment symbols are the same as the experiment design.
2.2.4. Fruit morphology, yield, and BER incidence
Fruit appearance is the first quality trait to consumers and determined by fruit size, shape
and color (Labate, 2007). The tomato fruit size, yield and BER morbidity harvested from
different treatments were displayed in Table 4. Results show that different treatments had
little effect on the fruit size, maximum D-value of L-diameter, S-diameter, individual fruit
weight was 0.46cm, 0.29cm and 17.8g/fruit respectively, which was found between SO and
CK, this implied that the fruit size was mainly determined by the genetic cultivar but has
few matters with exogenous Ca application. The highest tomato yield of 72.28 t ha -1 was
found in SL, followed by SO, CK obtained the lowest yield of 50.26 t ha -1 , which was 22.02
t ha -1 lower compared to SL. Overall, SL processed obvious advantages in improving the
tomato yield among the treatments. After applied with EM-Calcium, the BER incidence of
tomato fruits was well controlled to different extents, according to the results. SL ob‐
tained the lowest BER incidence of 9.42% compared to the other treatments, followed by
SR, recording as 10.28%. While ST had relatively less influences on the controlling of BER
incidence, only 2.23% lower than CK.
