东正教和顽固种子有什么区别

这关键区别在东正教和顽固的种子之间is that orthodox seeds survive during drying and freezing inex situ conservation，虽然在干燥和冻结的情况下，顽固的种子在异地保护过程中无法生存。

水分是种子中的水含量。种子水分表示为百分比。种子水分含量的少量变化对种子的储存产生了很大影响。为了合理地预测每个加入的可能存储寿命，应确定种子的水分含量。术语正统和顽固种子于1973年使用。E.HRoberts首次根据生理行为（例如种子水分含量）将种子归类为两类：东正教和顽固的种子。目前，种子根据种子水分含量分为三组：东正教，中间和顽固。

什么是正统种子？

正统种子是在干燥和冻结中在异地保护中生存的种子。根据美国农业部的细节，东正教种子承受干燥和冷冻的能力有所不同。据确定，有些种子比其他种子更敏感。通常，东正教种子是长寿命。东正教种子可以成功地将水分含量低至5％，而不会受伤。他们还能够忍受冻结。因此，它们也被称为耐药种子。此外，东正教种子的寿命延长，水分含量低和温度低。因此，东正教种子的原位保守性并非有问题。

东正教种子的例子是大多数年度农作物，两年一的作物和农林业种的种子。这些农作物的小种子正常。此外，正统种子植物包括Capsicum annum, Citrus aurantifolia，，，，凤凰dactylifera，，，，Hamelia Patens，，，，Lantana相机，，，，瓜贾瓦的皮西岛，，，，西方ancardium等等。大多数种子豆类and谷物该组也包括在该组中。东正教种子的寿命约为100年至2000年。

什么是顽固的种子？

顽固的种子s are the seeds that will not survive during drying and freezing in ex situ conservation. They cannot be stored for long periods like orthodox seeds because they do lose their viability. Typically, recalcitrant seeds are very large in size. These seeds cannot survive drying below 20-30% relative moisture content without any injury. They are also known as desiccation sensitive seeds. The storing of recalcitrant seeds is problematic in ex situ conservation. This is because their high moisture content encourages microbial growth and results in rapid seed deterioration. Secondly, storing recalcitrant seeds at freezing temperatures causes ice crystal formation that disrupts cell membranes. Therefore, plants that produce recalcitrant seeds must be stored in the growing phase rather than seeds.

顽固的物种属于树木和灌木。产生顽固性种子的植物的一些例子包括鳄梨，可可，椰子，菠萝蜜，七叶，芒果，橡胶，橡胶，茶，传统医学中使用的植物，有些园艺性的TRESS等。几周到几个月。

What are the Similarities Between Orthodox and Recalcitrant Seeds?

• 正统和顽固种子是基于种子水分含量的种子类型。
• Both terms were coined by Eric Roberts.
• 这些条款于1973年使用。
• 这些种子类型用于现代农业实践。

东正教和顽固种子有什么区别?

正统种子are the seeds that will survive during drying and freezing in ex situ conservation. In contrast, recalcitrant seeds are the seeds that will not survive during drying and freezing in ex situ conservation. So, this is the key difference between orthodox and recalcitrant seeds. Furthermore, orthodox seeds can successfully dry to moisture contents as low as 5% without any injury, while recalcitrant seeds cannot dry to moisture contents below 20-30% without any injury.

下面的并排比较表详细介绍了正统和顽固种子之间的差异。

摘要 - 东正教vs顽固的种子

E.H罗伯茨,正统的一个1973年,创造了条件d recalcitrant seeds. He classified seeds for the first time based on physiological behaviour such as seeds moisture content. The key difference between Orthodox and recalcitrant seeds is that orthodox seeds survive during drying and freezing in ex situ conservation, while recalcitrant seeds do not survive during drying and freezing in ex situ conservation.
