| Abstract | ||
| Calcium-rich products have been shown to improve the adverse effects of heat stress on cucumber plants. It is essential to explore how to enhance the heat tolerance of cucumber using calcium rich products complexes to Sugar Alcohol. The study explained the effects of Manni-Plex Ca-Zn (C1, Ca, 2.5% Zn), Manni-Plex Ca-Zn (C2, Ca, 2.5% Zn) and Manni-Plex Cal-Mag (C3, 7.9%Ca, 4.35%Mg) at ratio 100 ml/100L water, 200 ml/100L water and 300 ml/100L water, respectively, on cucumber plants (Cicely and Viva verities) under heat conditions by using the following parameters: plant height, leaf area, number of flowers, failed flower percent, GA3, ABA and antioxidant enzymes content. Under heat conditions, foliar application of Manni-Plex Ca-Zn, and Manni-Plex Cal-Mag were observed to increase cucumber vegetative growth and yield components. The obtained results also showed that the plant height, leaf area, number of flowers, GA3 and the activity of antioxidant enzymes (CAT and POD) content significantly improved in plants treated foliarly with Manni-Plex Ca-Zn , and Manni-Plex Cal-Mag compared to control plants. On the contrary, the highest content of ABA and failed flower percent were found in control plants compared to all the other treatments. Furthermore, the correlation study revealed that cucumber yield correlated positively with leaf area and number of leaves as well as negatively with failed flower percent. | ||
