Abstract

Rice is the most consumed food in the world, mainly in Asia and Africa. Malaysia is the second-largest rice importer in Southeast Asia after Indonesia. However, rice yield is limited by water stress. One alternative for a quicker strategy to mitigate water stress is through a combination of foliar spermine application and efficient rice management practices via image monitoring techniques using drone technology. The present study was aimed at evaluating the effects of spermine on rice physiological response and its association with aerial imagery and yield under reproductive during reproductive stage under water stress. The experiment was carried out under greenhouse conditions using a two-factorial randomized complete block design (RCBD), with foliar spermine treatment as the first factor and water stress as the second factor. Physiological parameters showed significantly higher tiller number per pot and photosynthesis rate by 29% and 31%, respectively. Correspondingly, the Normalised Difference Vegetation Index (NDVI) using aerial imagery monitoring showed an increased value in spermine treatments by 2% compared to control. Furthermore, NDVI readings and photosynthetic rate were positively correlated linearly with R2= 0.51. Interestingly, spermine treatments alleviated water stress effects by 40%, 17% and 12% in grain weight per pot, grain number per panicle and percentage filled grain. Biomass partitioning in roots improved by 44% in spermine treatments, even under water stress, due to an efficient translocation of assimilates. In conclusion, spermine foliar application significantly improved growth, grain filling and rice yield production, which was also supported by NDVI values using aerial imagery monitoring.
水稻在水分胁迫条件下对精胺叶面喷施的反应及其与航空图像监测的关系
大米是世界上消耗量最大的食品,主要集中在亚洲和非洲。马来西亚是东南亚仅次于印度尼西亚的第二大大米进口国。然而,水稻产量受到水胁迫的限制。通过使用无人机技术的图像监测技术,将叶面喷施精胺与高效的水稻管理方法相结合,是缓解水胁迫的快速策略之一。本研究旨在评估精胺对水稻生理反应的影响及其与航拍图像和水稻生育期产量的关系。实验在温室条件下进行,采用两因子随机完全区组设计(RCBD),叶面喷施精胺处理为第一因子,水分胁迫为第二因子。生理参数显示,每盆分蘖数和光合作用率明显增加,增幅分别为 29% 和 31%。相应地,利用航空图像监测的归一化植被指数(NDVI)显示,精胺处理的数值比对照组提高了 2%。此外,NDVI 读数和光合速率呈线性正相关,R2= 0.51。有趣的是,精胺处理在每盆粒重、每圆锥花序粒数和饱满粒百分比方面分别减轻了 40%、17% 和 12% 的水分胁迫影响。由于同化物的高效转运,即使在水分胁迫下,精胺处理也能使根部的生物量分配提高 44%。总之,叶面喷施精胺可显著提高生长、谷粒饱满度和水稻产量,这也得到了航空图像监测 NDVI 值的支持。
