How calcium and boron foliar application pollen fruit set cucurbits?5 answersFoliar application of calcium and boron has shown varying effects on pollen and fruit set in cucurbits. Studies suggest that calcium application can increase the number of pollen grains, seed production, and seed albumin content in sweet pepper seeds. On the other hand, boron application has been linked to a reduction in seed production and 1000 seed weight in sweet pepper seeds. In zucchini, boron application decreased the number of seeds per fruit, while a combined application of calcium and boron reduced seed germination speed index (SGI). However, calcium application alone in zucchini increased pollen production and the number of seeds per fruit without affecting seed quality, making it a recommended practice for seed production in zucchini. These findings highlight the importance of considering the specific effects of calcium and boron foliar application on pollen and fruit set in cucurbits.
What is the influence of arbuscular mycorrhizal fungi on the uptake of boron in avocado trees?5 answersArbuscular mycorrhizal fungi (AMF) play a crucial role in influencing the uptake of micronutrients like boron in plants. AMF association enhances the uptake of soil nutrients, including micronutrients, by improving root systems. The presence of AMF can lead to increased accumulation of boron in roots of mycorrhizal plants compared to non-mycorrhizal plants. Additionally, AMF colonization in roots is significantly influenced by soil characteristics such as moisture, carbon, nitrogen, and organic matter, which further impact the uptake of nutrients like boron. Therefore, the symbiotic relationship between avocado trees and AMF can potentially enhance the uptake of boron, contributing to the overall health and growth of the trees.
What is the effect of boron on growth and yield of potato?5 answersBoron has a significant effect on the growth and yield of potato. In a study conducted in Nepal, the combined soil application of boron and zinc resulted in the highest tuber yield per hill and overall high yield of potato. Another study in Bangladesh found that foliar boron spray increased plant height, number of branches, number of clusters, number of flowers, weight of each fruit, number of fruits per plant, and yield of tomato. Similarly, in a study on cowpea, the application of potassium and boron significantly increased plant height, number of nodules per plant, plant dry weight, number of pods per plant, seeds per pod, test weight, seed yield, stover yield, harvest index, gross returns, net return, and benefit cost ratio. Additionally, a study in Egypt showed that chelated boron, regardless of the source, enhanced potato growth, production, and quality. Furthermore, in a study on tomato, the combined effect of zinc and boron significantly increased the number of fruits per plant, fruit weight per plant, and yield per hectare.
Benefits of boron?5 answersBoron has been shown to have numerous health benefits. It plays a role in the repair and regeneration of injured tissue, and has a potential role in cardiac tissue regeneration after injury. Boron is essential for growth and has pleiotropic effects, ranging from anti-inflammatory and antioxidant effects to the modulation of different body systems. It is important for maintaining animal health, preventing nutritional disorders, and enhancing immune function. Boron promotes bone health, brain function, and modulates the immune or inflammatory response. It also affects hormone action and is associated with a reduced risk for some types of cancer. An intake of less than 1.0mg/day inhibits the health benefits of boron, so it is recommended to consume a diet rich in fruits, vegetables, nuts, and pulses to increase boron intake.
What is the function of calcium in plants?5 answersCalcium plays multiple roles in plants. It is involved in external Ca2+-induced cytosolic Ca2+ increase, stomatal movement regulation, and Ca2+ signaling. Calcium is essential for growth and development of plants and functions as an intracellular secondary messenger. It regulates cell wall rigidity, stabilizes cell membranes, and allows expansion of pollen tubes or root hairs during tip growth. Calcium also functions as a secondary messenger in various processes such as plant growth, fertilization, and stress responses. It activates downstream transcription factors, transporters, or channels leading to specific physiological responses. Calcium is important for the growth of plants, fruit development, and resistance to diseases. It supports metabolic processes, activates enzymatic systems, and contributes to membrane stability and cell integrity. Calcium is also involved in stress signaling and confers protective effects on plants under salt stress. Overall, calcium is a crucial element for plant growth, development, and response to various stresses.
How boron help in cotton quality?5 answersBoron plays a crucial role in improving cotton quality. It enhances plant growth, yield, and fiber quality attributes. Boron deficiency can lead to poor seed cotton yield and fiber quality. Adequate boron application significantly improves growth, physiological parameters, and fiber quality characteristics of cotton. Soil application of boron improves cotton growth, yield, physiological parameters, and fiber quality traits. Boron application at the rate of 2.60 mg kg-1 of soil has pronounced effects on various growth, yield, physiological, and fiber quality traits. Boron helps in increasing the number of bolls, boll size, boll weight, seed cotton yield, photosynthesis, transpiration rate, stomatal conductance, water use efficiency, ginning out turn, staple length, fiber fineness, and fiber strength. Overall, boron application improves cotton quality by enhancing plant growth, yield, and fiber characteristics.
