The growth of plants hinges on a complex interplay of biochemical and physiological activities across various growth stages. These intricate processes dynamically adapt to different environmental conditions, shaping both plant development and productivity. This study explores the impact of greenhouse climate on the growth, yield, and biochemistry of winter-grown cherry tomatoes 'Cheramy F1'. A randomized complete block design (RCBD) under split plot arrangements (3 Rows) with three replications (3 plants from each row) was adopted. The data were collected on various dates during the period extending from December to March of two consecutive growing seasons in 2022 and 2023, and presented as averages. An analysis of variance was applied to statistically analyze the collected data at a confidence level of p < 0.05. The climatic conditions in the greenhouse were calculated as temperature ranging from a minimum of 10.5 °C to the maximum of 41.3 °C by an average of 21.2 °C during the vegetative stage and from 8.2 °C to 32.3 °C by an average of 20.9 °C during the fruit-bearing stage, with an average CO concentration fluctuated within the range of 385.61 ppm to 510.30 ppm and an average light intensity of 94.62 to 240.45 W/m². This study assessed various growth parameters such as plant height, leaf growth, stem diameter, leaf spacing, leaf count, leaf area, and inflorescence count per plant, and suggested the optimum range of greenhouse conditions for each stage. The key results of this study revealed the Progressive Growth Report (PGR), predicting daily potential growth rates of plants: plant height, 2.86 to 3.81 cm/day; growth rate of mature older leaf: 0.003988 m/day; middle younger leaf: 0.008733 m/day; top nascent leaf: 0.010722 m/day; three to five leaves per week; and one inflorescence per week. In our accidental observation, we noticed unusual plant growth and yield responses because of the various growing postures and positions that the plants adopted in the greenhouse. An exceedingly significant difference among the inflorescences was found in view of their growth, productivity and biochemical composition. A non-significant interaction was found between the fruit keeping quality (shelf days), fruit height, fruit diameter, and inflorescence number. The present study results highlight the possible responses of greenhouse-grown cherry tomatoes to different ranges of temperature, light intensity, and CO concentrations, offering valuable insights for optimizing greenhouse cherry tomatoes cultivation.
植物的生长取决于各种生长阶段中生化和生理活动的复杂相互作用。这些复杂的过程会根据不同的环境条件动态适应，从而影响植物的发育和生产力。本研究探讨了温室气候对冬季种植的樱桃番茄“Cheramy F1”生长、产量和生物化学的影响。采用裂区设计（3 行）的随机完全区组设计（RCBD），每个区组有 3 个重复（每行 3 株）。数据于 2022 年和 2023 年连续两个生长季节的 12 月至 3 月期间的不同日期收集，并以平均值表示。置信水平为 p<0.05 时，应用方差分析对收集的数据进行统计分析。温室中的气候条件计算为，在营养生长阶段，温度范围从 10.5°C 到 41.3°C，平均为 21.2°C，在结果期，温度范围从 8.2°C 到 32.3°C，平均为 20.9°C，CO2 浓度平均波动范围为 385.61 ppm 至 510.30 ppm，平均光照强度为 94.62 至 240.45 W/m²。本研究评估了各种生长参数，如株高、叶片生长、茎直径、叶片间距、叶片数、叶面积和每株植物的花序数，并提出了每个阶段温室条件的最佳范围。本研究的主要结果是预测植物日潜在生长速率的“渐进生长报告（PGR）”：株高 2.86 至 3.81 cm/天；成熟老叶的生长速率：0.003988 m/天；中叶：0.008733 m/天；顶生嫩叶：0.010722 m/天；每周三叶；每周一花序。在我们的偶然观察中，我们注意到植物由于在温室中采用的各种生长姿势和位置，生长和产量表现出异常。观察到花序的生长、生产力和生物化学组成有显著差异。果实保持质量（货架期）、果实高度、果实直径和花序数之间的非显著相互作用。本研究结果突出了温室种植的樱桃番茄对不同温度、光照强度和 CO2 浓度范围的可能反应，为优化温室樱桃番茄种植提供了有价值的见解。
