“…Recently, Maeda and Ahn (2021) reviewed many studies related to cucumber production by considering environmental factors and training methods based on yield components. They discussed different training systems, pinching and lowering methods, and the effects of environmental factors, such as the temperature, humidity, CO 2 concentration, irrigation, and nutrition, on the yield and yield components.…”

In this study, we analyzed European medium-sized cucumber (Cucumis sativus cv. Zeco) growth and yield in a high-wire growing system using different training methods in a smart greenhouse. The experimental treatments were applied as follows: 4P1S, four plants were trained on a single main stem; 4P2S, four plants were trained to one main stem plus a lateral stem from the seventh node in a slab; 3P2S, three plants were trained on two stems from the seventh node of a slab. The average daily drainage volume was lower in the 4P2S than other treatments with approximately 10% lower drainage ratio than that in 4P1S. The retained volume, the difference between the total irrigation and drainage volumes, was 154 L•m -2 for 4P1S, 199 L•m -2 for 4P2S, and 151 L•m -2 for 3P2S. Water use (L•kg -1 fruit) was in the order 4P2S (14.88) > 3P2S (12.34) ≥ 4P1S (12.00). The plant height, number of nodes, and length from the apex to the last flower were significantly lower in the 3P2S group than that of other treatments. Higher leaf dry weight was observed with the 4P1S treatment than with the 4P2S treatment. The number of stem nodes was highest in 4P1S, indicating a good relationship between this and the leaf dry weight. The number of fruits and fruits per plant was in the order of 3P2S > 4P2S > 4P1S, indicating that it was higher in the 6 stems per slab group than in the 4-or 8-stem groups. There was no significant difference in the fruit yield per unit area (m 2 ). It was 13.0 kg•m -2 for all treatments, which was about 1.6-fold higher than that from the greenhouse cultivation in Korea (7.96 kg•m 2 ). It may be due to the cucumber variety with a high-wire growing system. The yield for each week was constant in the 4P1S group in accordance with the CSR (Cumulative Solar Radiation) level, whereas there was a large variation in the weekly yield harvested from plants grown with the 4P2S and 3P2S treatments. All the integrated results in the present study suggested that training one main stem per slab might be better for the European cucumber variety in terms of the water consumption, yield, and workload.

“…Cucumber fruits were harvested and weighed once their weights and lengths reached approximately 100 g and 22 cm (Japanese standards) [38]. Plant yield components were expressed in terms of total and marketable fresh fruit weights, marketable number of fruits, and the percentage of non-marketable fruits.…”

Grafted cucumber plants were grown in a new hydroponic system (“Kappa Land”, Mitsubishi Chemical Aqua Solutions, Co., Ltd., Tokyo, Japan). Two different nutrient management methods were applied to the plants as treatments: Electrical Conductivity-based Management (ECM) and Quantitative Nutrient Management (QNM). During the growth period, we examined plant growth characteristics and productivity, fruit growth characteristics and quality, and nutrient use characteristics. The results revealed that the QNM technique significantly reduced the nutrient supply rate per plant for Ca2+, SO42−, and N by 28.5%, 25.5%, and 23.3%, respectively. Similarly, the absorption rates per plant of SO42−, K+, and PO43− were reduced by 17.8%, 11.9%, and 10.9%, respectively. However, N, Ca2+, and Mg2+ absorption rates slightly increased in the QNM treatment. The nutrient wastes generated per kilogram of produced fruits were also reduced by 66.4%, 60.7%, and 30.2% for N, Ca2+, and SO42−, respectively. Although the QNM technique reduced the plant’s leaf area, it significantly increased its total length by 9.4%. The total and marketable yields were not significantly different between the ECM (9.0 and 8.0 kg plant−1) and QNM (9.1 and 8.2 kg plant−1) treatments. However, the QNM treatment produced the highest total dry matter of 617 g plant−1, surpassing the ECM treatment by 6.9%. On the other hand, differences in nutrient management methods did not significantly affect fruit quality, including total soluble solids, water content, skin color, size, and shape. These results suggest that with the QNM method, it is possible to produce quality cucumbers with high nutrient use efficiency while protecting the environment from nutrient wastes.

“…Humidity is closely related to the sex differentiation of cucumbers. Proper humidity will reduce the node position of the first female flower and increase the number of female flowers ( Ito and Saito, 1960 ; Maeda and Ahn, 2021 ). Research shows that higher soil and air humidity are conducive to the female formation of plants.…”

Cucumber belongs to the family Cucurbitaceae (melon genus) and is an annual herbaceous vegetable crop. Cucumber is an important cash crop that is grown all over the world. From morphology to cytology, from canonical genetics to molecular biology, researchers have performed much research on sex differentiation and its regulatory mechanism in cucumber, mainly in terms of cucumber sex determination genes, environmental conditions, and the effects of plant hormones, revealing its genetic basis to improve the number of female flowers in cucumber, thus greatly improving the yield of cucumber. This paper reviews the research progress of sex differentiation in cucumber in recent years, mainly focusing on sex-determining genes, environmental conditions, and the influence of phytohormones in cucumber, and provides a theoretical basis and technical support for the realization of high and stable yield cultivation and molecular breeding of cucumber crop traits.
