High Temperature and the Ethylene Antagonist 1-Methylcyclopropene Alter Ethylene Evolution Patterns, Antioxidant Responses, and Boll Growth in <i>Gossypium hirsutum</i>

American Journal of Plant Sciences (2013)

The cotton (Gossypium hirsutum L.) crop experiences high temperatures during flowering and boll development, but information regarding the impact of ethylene inhibition and high temperature on early boll development is limited.The objective of this study was to determine the effects of high temperature and the anti-ethylene compound 1-methylcycloprone (1-MCP) on G. hirsutum boll development.Treatments consisted of temperature regime (38/20˚C and 30/ 20˚C), 1-MCP treatment, and days past anthesis (DPA).High temperature decreased ethylene synthesis by 61% at 2 DPA, and 1-MCP caused a 40% decrease in ethylene production at 1 DPA.Glutathione reductase activity increased under high temperature, whereas superoxide dismutase activity (SOD) and membrane peroxidation (malondialdehyde content) remained unchanged.1-MCP treatment did not affect GR activity in developing bolls.High temperature and 1-MCP treatment increased the weight of cotton bolls collected 8 DPA with an increase of 0.7 and 1 g, respectively.We propose that increased GR activity in bolls exposed to high temperature may mitigate oxidative damage.Additionally, we conclude that ethylene inhibition (either high temperature or 1-MCP-induced) immediately after flowering (1 or 2 DPA) could potentially have positive impacts on early boll growth.

How potassium deficiency alters flower bud retention on cotton (Gossypium hirsutum L.)

Archives of Agronomy and Soil Science (2018)

Potassium (K) is fundamental for plant growth and development but despite the increased quantities of fertilizers applied, incidents of K deficiency are commonly observed. The objective of this study was to record the effects of K deficiency during cotton's (Gossypium hirsutum L.) early reproductive stage on carbohydrate content and metabolism, total antioxidant capacity and oxidative damage of cotton flower buds as well as the physiology of the leaf, subtending to the flower buds. Growth chamber experiments were conducted using cotton cultivar DP0912 and treatments consisted of normal K and deficient K fertilization for the duration of the experiment. Potassium deficiency resulted in significant oxidative damage in the cotton flower buds, despite the substantial increase in their total antioxidant capacity. Sucrose metabolism of the flower buds was markedly affected resulting in significant reductions in all non-structural carbohydrate concentrations. Furthermore, K deficiency disturbed leaf physiology leading to increased membrane damage, decreases in chlorophyll and carotenoid content and ultimately leaf photosynthetic rates. Concomitant increases in specific leaf weight under K deficient conditions indicated reductions in photoassimilate translocation, which in conjunction with the disruptions observed in flower bud sucrose metabolism, due to the insufficient antioxidant response, resulted in significant decreases in flower bud retention.

Partitioning of potassium in the cotton plant during the development of a potassium deficiency

Journal of Plant Nutrition (1996)

Craig W. Bednarz Derrick M. Oosterhuis

Abstract Visual potassium (K) deficiency symptoms of modern cotton (Gossypium hirsutum L.) cultivars are similar to classical descriptions. Unlike classical descriptions, however, they occur first at the top of these more heavily fruiting cultivars and progress from younger to older leaves. Studies were initiated to closely monitor the development of K deficiency symptoms in a modern cotton cultivar. Growth chamber experiments were conducted in 1993 and 1994 to determine how K is partitioned throughout cotton plants during the development of K deficiency symptoms. Experiments were conducted in 8‐L sand filled pots in a growth chamber at the Altheimer Laboratory in Fayetteville, Arkansas. Two treatments were established at the pin‐head square growth stage 35 days after planting and consisted of nutrient solutions containing 0 and 6 mM K. The onset of K deficiency was first detected in upper canopy petioles 4 days after treatment establishment (DATE). On this day, petiole K concentration in the plus‐K treatment was approximately 70 to 80 g.kg‐1 (w/w) and 40 to 60 g.kg‐1 (w/w) in the no‐K treatment. Differences in leaf K were also observed first in the upper canopy with approximately 30 g.kg‐1 (w/w) in the plus‐K leaves and 20 g.kg‐1 (w/w) in the no‐K leaves 4 DATE. Significant differences in petiole and leaf K were next observed in mid and lower canopy petioles 14 and 28 DATE, respectively. Differences in fruit K were not observed until 28 DATE. Thus, these experiments suggest upper canopy petioles and leaves exhibit lower levels of K than lower canopy petioles and leaves at given times and conditions. These results should be considered when sampling to detect a K deficiency.
