Abstract

Salt stress is induced by Nacl and it minimizes the growth owing to variation in interior plant structure. The present work was designed in line to investigate the behavior of Gazania harlequin (L.) seedlings were raised with dissimilar salt combinations (25 ppm, 50 ppm, 75 ppm & 100 ppm of NaCl solution). The CRD experiment with 4 repetitions was done. The NaCl treatments were repeated in 4 times with 20 days interval totally for 80 days after transplanting in pots. Anatomical observations were recorded by the microscope of in Nacl affected growth leaf. The results illustrated that salinity levels had negative effect on anatomical characters as (xylem region, phloem region, cortex region, epidermis region and density of leaf lamina). So, it is concluded from study that control treatment (without salinity effect) showed improved outcome comparatively others treatments which were under saline situation. As the salinity increases ultimately it affects leaf anatomy of plant.

Now sectioning coastal redwoods!

Molly here, it’s been quite a busy semester! I’ve been organizing samples post fieldwork, getting ready for a conference, and mentoring new undergrads in the lab! 

Most recently, I’ve started to embed and section my Sequoia samples from last year. It is very exciting because the anatomy is almost visible with the naked eye. Below is a close up photo of my sections before the staining and mounting process, still embedded in paraffin. You can *almost* clearly see the anatomical details! 

Here’s a photo from the binoculars of the microscope under 5x magnification. It’s still in paraffin but I wanted to share these Sequoia sections. Although not stained, a lot of the cellular anatomy is pretty clear!

Measurements from these sections will show the variability of leaf anatomy throughout its distribution along the northern coast of California, and whether or not they reflect the climate they inhabit, however small it is compared to Taxodium.
