Using heat-balance stem flow gauges, we were able to measure directly and continuously the sap flow rates in two pairs of soybean [Glycine max (L.) Merr.] isolines differing in stomatal frequency. Plants with high stomatal frequency transpired significantly more water than the low stomatal frequency plants at high soil moisture levels. Under low soil moisture levels, the water use rate decreased greatly for the high stomatal frequency plants. Plants with low stomatal frequency were able to maintain greater sap flow rates than those with high stomatal frequency. Higher leaf temperatures associated with the low stomatal frequency plants were likely due to lower transpiration rates which reduced evaporative cooling especially under well-watered conditions. Key words:Glycine max (L.) Merr., transpiration, water deficits

We report the production of hexaploid plants of interspecific hybrids of Pennisetum, with the ultimate aim to improve the biomass yield, drought tolerance and multicut behaviour of this genus. Chromosome doubling was achieved with the application of colchicine at three different concentrations (0.05, 0.1 and 0.2%) for two time durations (12 and 24 hours). The root slips and stem cuttings of interspecific hybrids were used for treatment and the root slips were found to be more efficient. The preliminary screening to select the putative hexaploid plant was done based on stomatal frequency and morphology. Plants containing significantly lower stomatal frequency and larger stomata size were selected for further analysis by chromosome counting. This experiment confirmed that 0.1% concentration of colchicine treatment to root slips for 24 hours was more effective to induce the amphiploids in Pennisetum.

Stomatal Frequency

Effect of soil moisture on stomatal frequency and distribution of mustard was studied. The irrigated plants had significantly higher number of stomata on both the adaxial and abaxial surfaces of leaf than the rainfed plants. No significant effect of soil moisture on stomatal frequency of stem and pod was found. Key words: Mustard, soil moisture, stomatal frequency, pod. Bangladesh J. Sci. Ind. Res. 42(3), 353-356 2007

Herbicide Response

Canada thistle(Cirsium arvense(L) Scop.) includes many regional races that are heritable, distinct ecotypes. When cultured at Bozeman, Montana a group of these ecotypes varied in phenological, morphological, and anatomical characteristics. These ecotypes also responded differently to (2,4-dichlorophenoxy)acetic acid (2,4-D) and 3-amino-s-triazole (amitrole). Stomatal frequency and area on leaves also differed among ecotypes studied. Although stomatal frequency and stomatal area differed among the ecotypes studied, there was no correlation with herbicide response. Apparently, stomata were not a significant portal of entry of 2,4-D into the upper surface of Canada thistle leaves.
