Abstract

BACKGROUND

Biostimulants positively impact plant growth, yield, and chemical composition while enhancing tolerance to biotic and abiotic stress. Phosphite (Phi), a phosphate analog, has been proposed as a biostimulant due to its advantages over traditional phosphate fertilizers and herbicides.

METHODS

This study evaluated the effects of Phi on sugarcane seedlings (CP 72-2086) under conventional (non-stress) and osmotic stress conditions during multiplication. Seedlings were treated with Phi at 0.1, 0.3, and 0.5 mM (derived from HPO) for 30 days, followed by 7 days of osmotic stress induced with 10% polyethylene glycol 6000 (PEG).

RESULTS

Phi significantly increased leaf length, width, and number, as well as shoot count. Additionally, it enhanced foliar concentrations of chlorophylls and , sugars, and amino acids under both conventional and osmotic stress conditions. In conclusion, Phi serves as an effective inorganic biostimulant for sugarcane (CP 72-2086) during multiplication, stimulating seedling growth and modulating essential biomolecule concentrations.

摘要

背景

生物刺激素对植物生长、产量和化学成分有积极影响，同时增强对生物和非生物胁迫的耐受性。亚磷酸盐（Phi）是一种磷酸盐类似物，因其相对于传统磷肥和除草剂的优势而被提议作为一种生物刺激素。

方法

本研究评估了Phi在常规（非胁迫）和渗透胁迫条件下对甘蔗幼苗（CP 72-2086）增殖的影响。用0.1、0.3和0.5 mM（源自HPO）的Phi处理幼苗30天，随后用10%聚乙二醇6000（PEG）诱导7天的渗透胁迫。

结果

Phi显著增加了叶片长度、宽度和数量，以及茎数。此外，在常规和渗透胁迫条件下，它都提高了叶片中叶绿素a和b、糖分和氨基酸的浓度。总之，Phi在甘蔗（CP 72-2086）增殖过程中是一种有效的无机生物刺激素，刺激幼苗生长并调节必需生物分子的浓度。
