林业林业林业林业林业
农业农业农业农业
植物科学植物科学

背景情况:

松子产量 (PY) 的全球下降引发了人们的担忧,因为对松子的需求很高.
PY是一个关键的作物特征,影响了Pinus pinea种植的经济可行性.

研究的目的:

调查影响PY在Pinus pinea的因素.
在非原生智利人群中比较PY和重型和轻型体之间的相关特征.

主要方法:

一项为期10年的研究监测了七个智利种植园的圆重量,种子/松子形态和PY.
分析了560个的重量,数量和损伤.
混合线性模型和回归树用于统计分析.

主要成果:

智利的平均子重量 (474克) 超过了本地范围 (300克).
与轻型圆相比,重型圆的松子数量 (125比89) 和PY (4.05%比3.62%) 显著更高.
重型体的种子损伤率较低 (9.0%与15.9%相比).

结论:

松子产量受到种子/松子形态和种子健康的影响.
圆重量是Pinus pinea中PY的一个关键决定因素.
诸如施肥和灌等农业实践可能会增加重型生产,并促进PY.

Production of Organic Acids

Lactic acid, an important organic acid extensively applied in food, pharmaceutical, and biodegradable polymer industries, is primarily produced via microbial fermentation. This method is favored over chemical synthesis due to its environmental sustainability and capacity for enantiomerically pure product formation. Among various microbial processes, the fermentation of starch-based substrates stands out due to the abundance and renewability of raw materials like corn and potatoes.Hydrolysis of...
