The purpose of this lab was to find the water potential of a potato cell. The problem of this lab was‚ if there was a high molarity of solute‚ would it have a positive or negative water potential? The hypothesis of the experiment was‚ if there is a high molarity of solute ...
Water Potential of Potato Osmosis andwaterpotentialAim of the experiment: Finding thewaterpotentialofpotato. Biological principles: Independent variable: concentration of the solution. Dependent variable: percentage changed in weight of thepotatostrips. Controlled variable: size of thepotatostrips‚ it can...
The water uptake of potato tuber tissue under the influence of chloramphenicol and actinomycin D was compared with that of indoleacetic acid. Both antibiotics decreased the water absorption as compared to the effect of indoleacetic acid. This decrease, in the early hours (3 to 6 h), is due ...
The Water Potential of Plant Tissue Aim: To find the water potential of plant tissue by investigating the effects of varying concentrations of sugar solutions on the amount of osmotic activity between the solution and potato cylinders. Hypothesis: Osmosis is defined as the net movement of water fr...
Different authors have proposed leaf Relative Water Content (RWC) as a better indicator of leaf water status compared to leaf water potential for wheat. RWC is easy to measure and calculate, by simply weighing fresh leaf tissue after excision (FW), at full turgor (TW) and after drying (DW...
The plant growth response under saline irrigation is a function of the salt's concentration in the soil solution (particularly Na+ and Cl−) and the matrix potential of the soil (Paranychianakis and Charzoulakis, 2005). To maintain adequate soil-water availability it is essential to restrict...
of a double layer, which reduces the rate of transpiration of the leaves thereby maintaining the water status of the plant13,14. Kh is also used as a plant bio-stimulant and an effective natural resource with the potential to increase organic matter, regulate osmotic potential, improve ...
In potato, little is known on how drought affects the interactions between potato and its rhizosphere microbiomes. The aim of this study was to investigate the potential role of the rhizosphere microbiome in sustaining potato growth under reduced soil moisture. We introduced in our system, plant ...
Cold stress can impact plant biology at both the molecular and morphological levels. We cultivated two different types of tobacco seedlings using distinct seeding methods, observing significant differences in their cold tolerance at 4 °C. After 12&
In a sand culture experiment with Brassica juncea, B deficiency decreased DM accumulation, total water content of plants and water potential and water satu... PN Sharma,T Ramchandra - 《Indian Journal of Plant Physiology》 被引量: 96发表: 1990年 Biomass accumulation and allocation in soybean as...
