背景情况:

对于非本地水果品种来说,最优的收获时间至关重要,尤其是在半干旱的气候中.
当地对萨维的"奇妙"石榴收获的知识有限,需要进行科学研究.

研究的目的:

根据水果特征来确定"神奇"石榴的理想收获时间.
优化收获时间,以提高水果的质量和可销售性. 在一个半干旱地区.

主要方法:

一个为期两年的随机完全块设计研究 (2021-2022年) 用四个块.
果实在开花后155天,170天和185天 (DAF) 的三个时间间隔收获.
分析物理和生物化学性质,包括重量,颜色,可溶性固体,pH值,安素,和酸度.

主要成果:

收获延迟显著增加了水果的重量,的重量和果汁的百分比.
在185 DAF时观察到最高的总可溶固体 (17.76 °Brix),pH (3.41) 和安东含量 (32.56 mg/L).
到第三个收获 (185 DAF) 时,水果裂变增加到30.25%.

结论:

萨维的"神奇"石榴的最佳收获窗口是10月12日至27日 (170-185 DAF).
这一时期平衡了优越的水果质量与可接受的水果破裂率.
这些发现为在半干旱条件下最大限度地提高石榴产量和营养价值提供了实际指导.

Fruit Development, Structure, and Function

Fruit Development, Structure, and Function

Fruits form from a mature flower ovary. As seeds develop from the ovules contained within, the ovary wall undergoes a series of complex changes to form fruit. In some fruits, such as soybeans, the ovary wall dries; in other fruits, such as grapes, it remains fleshy. In some cases, organs other than the ovary contribute to fruit formation; such fruits are called accessory fruits.

Biological Clocks and Seasonal Responses

Biological Clocks and Seasonal Responses

The circadian—or biological—clock is an intrinsic, timekeeping, molecular mechanism that allows plants to coordinate physiological activities over 24-hour cycles called circadian rhythms. Photoperiodism is a collective term for the biological responses of plants to variations in the relative lengths of dark and light periods. The period of light-exposure is called the photoperiod.
