Kiwi fruit in the production process is an important quality indicator is the size of the fruit, generally sold in the market of kiwifruit, the weight of its single fruit is generally more than 80 grams. Then, in the process of planting and development of kiwifruit, what is the impact on the fruit size? In research work, the most studied is the relationship between fruit size and seeds. What is the relationship between them? Since the kiwifruit seed is relatively small, the seeds can be counted using an automatic counting instrument during the test.
By investigating 30 fruit sizes ranging from LQ-8 to QY82-4, the number of seeds and fruit weight were obtained. Within the measured fruit weight, the fruit weight was highly positively correlated with the seed number, and the correlation coefficient reached a very significant level. If the above sampling range is divided into 2 segments, with 70 g of large fruit and the corresponding number of seeds as the demarcation point, the analysis results show that when the seeds reach a certain number or more, the correlation between the number of seeds and the fruit weight is not obvious. We also investigated the fruit weight of 20 D-25 plants with fruit weight between 74 and 76 g. We found that the number of seeds was between 504 and 772. The limiting factor at this time no longer seemed to be the number of seeds, but other The condition, below this certain number of seeds, has a strong dependence on the number of seeds.
If the above-mentioned certain number of seeds is called a threshold, different species (strains) have different thresholds. The stimulating effect of seeds on fruits is mainly achieved through the production of multiple hormones, but only when a certain number (threshold) is reached, sufficient hormone levels can be maintained to ensure the competition of fruits for nutrients. Under such a metabolic gradient, the fruit can grow normally.
A detailed analysis of the seed counts and the relationship between fruit weight and seed number of different varieties of kiwifruit by automated counting instrument showed that the two are highly positively correlated within a certain range. The production of large fruit must be fully pollinated and inseminated, so that the number of normally-developed seeds does not fall below the threshold. In this experiment, the seed threshold of the LQ-8 strain was 450, and the QY82-4 strain was 600. This can be achieved in production by selecting good male plants with high affinity, bee feeding or artificial pollination. Of course, the size of the fruit is also affected by other factors, nutrition, moisture, etc. are the main factors. Therefore, strengthening fertilizer management, proper pruning, and fruit thinning are important measures to improve the fruit rate.
