| This study was conducted to examine the effects of electrical conductivity (EC) and rootstock on initial growth and physiological response of grafted pepper in protected cultivation. The pepper (Capcicum annuum L.) cultivars 'Nokgwang' was used as scions, and the cultivars used as rootstocks were Capcicum annuum L: 'Kataguruma', 'Conesian hot' and 'Tantan'. The scion cultivar left ungrafted was used as a control. Two experiments were to examine the effects of the EC levels of nutrient solution on the growth and physiological response of grafted pepper, respectively. Nutrient solution was supplied with three level (1.5, 3.0, 5.0dS/m). By the change of nutrient solution EC level, the plant growth of all seedlings decreased with the increase in EC level. grafted seedling was grafted onto rootstock cultivar 'kataguruma' showed higher growth than the other cultivar at the EC 5.0dS/m level. But this result was slightly different by cultivation time (spring and fall). The total N and P concentration were increased with the increase in EC level, but the Ca and Mg concentration were decreased. Photosynthetic rate of ungrafted seedlings decreased at the EC 5.0dS/m level. But there was no difference between EC 1.5 and 3.0dS/m level. Grafted seedlings showed lower photosynthetic rate at the EC 5.0dS/m level. The activity of SOD do not have a uniformly tendency by the EC level. With the EC 5.0dS/m level, the activity of APX attained higher level than the other EC level. Further study will be needed to examine additional cultivation experiment for more variable rootstock, and development of rootstock for salinity tolerance. |
