Outline
Melon is an important cash crop in Hainan, and its pollination is mainly hormone pollination, which is easy to cause fruit deformity and accompanied by different degrees of flavor and quality decline, affecting commodity rate and planting efficiency. Melon Jiyoumi 29 was used as the experimental material. Different artificial pollen combinations were used to pollinate to compare with hormone pollination. The growth status of plants and fruits, the internal quality of fruits and the activities of key enzymes for sucrose accumulation, and analyzed the effects of pollination on the growth of plants and fruits were studied. Different pollination methods had great effects on plant height, stem diameter and biomass, fruit weight and hardness, and the stem diameter and biomass and fruit weight treated with T1 were significantly higher than those of the other treatments. The plant height and fruit hardness treated with CK were significantly higher than those of the other treatments. There were significant differences among different pollination methods on each index of melon fruit internal quality, and T1 treatment had the best effect, and its soluble solids, soluble sugar, sucrose content, fructose content and glucose content were significantly higher than CK treatment. The activity of sucrose synthase (SS) treated with T4 was relatively high during fruit growth and development. The sucrose phosphate synthase (SPS) in T1 treatment maintained a high level during the fruit growth and development, and the acid invertase activity in T1 and T2 treatment reached the highest at the 40th day after pollination, which were 93.69 U/g and 88.54 U/g respectively. The treatment of T1 (strong pollen vitality × high stigma receptivity) has the best effect on the growth and fruit quality of melon plants after artificial pollen pollination.
