The Effect of Water Stress on Some Morphological, Physiological, and Biochemical Characteristics and Bud Success on Apple and Quince Rootstocks

Abstract

The effects of different water stress (control, medium, and severe) on some morphological, physiological, and biochemical characteristics and bud success of M9 apple and MA quince rootstocks were determined. The results showed that water stress significantly affected most morphological, physiological, and biochemical characteristics as well as budding success on the both rootstocks. The increasing water stress decreased the relative shoot length, diameter, and plant total fresh and dry weights. Leaf relative water content and chlorophyll index decreased while electrolyte leakage increased with the increase of water stress in both rootstocks. An increase in water stress also resulted in reduction in budding success in Vista Bella/M9 (79.33% and 46.67%) and Santa Maria/MA (70.33% and 15.33%) combinations. However, the water stress in Santa Maria/MA was more prominent. The increase in water stress resulted in higher peroxidase activities as well as phenol contents in both rootstocks. Although catalase activity, anthocyanin, and proline contents increased with the impact of stress, this was not statistically significant. The results suggest that the impact of stress increased with the increase of water stress; therefore, growers should be careful when using M9 and MA rootstocks in both nursery and orchards where water scarcity is present.

Diadegma insulare development is altered by Plutella xylostella reared on water‐stressed host plants

“…Reduced water availability results in limited cell division due to impaired mitosis and obstructed cell elongation due to loss of turgor that ultimately diminishes growth (Farooq et al 2009). Water deficit influences most of the morphological and physiological traits of host plants such as plant height, diameter, growth, plant total fresh and dry weight, and leaf water content (Zhang et al 2009;Bolat et al 2014), depending on the host plant species, and the level, duration and type of stress (Mattson and Haack 1987;Grime and Compbell 1991). In the present study, both host plants showed reduced leaf water potential under water-deficit conditions.…”

Morphological, physiological, biochemical characteristics and bud success responses of myrobolan 29 c plum rootstock subjected to water stress

“…Similar results were reported by Sauve et al (1991) for Golden Delicious/M111 budding combination, which was severely affected in pre and post chip budding in −5 to −25 kPa water stress applications. Bolat et al (2014) reported that chip budding success was gradually reduced in Vista Bella apple/M9 apple rootstock and Santa Maria pear/MA quince rootstocks combinations under gradual increase of water stress.…”

The Dynamic of some Biochemical Indicators at Species of Medicinal Plants from Areas of Suceava County, Romania, Emerged under the Mining Pollution Influence

“…4) Our results concords with those from the scientific literature that signalize a strong ROS accumulation and, implicitly, a CAT activity's increase at species derived from uranium polluted environments 55 . In the same time, the prominent differences of enzymatic activity could be explain by the seasonal variations, but also zonals, of the hydric level, the hydric regime potencying the forming process of the superoxidic radical, fact that has as consequence a sustained SOD activity and, implicitly, of CAT that block the hydrogen peroxide accumulation 56,57 . On the other hand, the lower catalasic activity signalized at Mentha longifolia L., comparatively with Plantago major L., can be explained by the genetic background and the species specificity, but also by the epigenetic adjustment through the interaction with environmental factors 58 .…”
