Leaves are green due to the presence of a green coloured pigment called chlorophyll. the main function of chlorophyll is to perform photosynthesis in the presence of sunlight. Chlorophyll is located in a plant’s chloroplasts, which are tiny structures in a plant’s cells. Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green.

Description for the DLP9500UV
DLP9500UV is a digitally controlled micro-electromechanical system(MEMS) spatial light modulator (SLM). When coupled to an appropriate optical system, the DLP9500UVcan be used to modulate the amplitude, direction, and/or phase of incoming light.
The DLP95000UV chipset is a new digital micromirror device (DMD)addition to the DLP®Discovery™ 4100 platform, which enables highresolution and high performance spatial light modulation beyond the visible spectrum into the UVAspectrum (363 nm to 420 nm). The DLP9500UV DMD is designed with a special window that is optimizedfor UV transmission.
The DLP9500UV is the 0.95 1080p DMD, with a hermetic package, that issold with a dedicated DLPC410 controller required for high speed pattern rates of >23000 Hz(1-bit binary) and >1700 Hz (8-bit gray), one unit DLPR410 (DLP Discovery 4100 ConfigurationPROM), and two units DLPA200 (DMD micromirror drivers). Refer to DLPC410, DLPA200, DLPR410, andDLP9500UV Functional Block Diagram.
Reliable function and operation of the DLP9500UV requiresthat it be used in conjunction with the other components of the chipset. A dedicated chipsetprovides developers easier access to the DMD as well as high speed, independent micromirrorcontrol.
DLP9500UV is a digitally controlledmicro-electromechanical system (MEMS) spatial light modulator (SLM). When coupled to an appropriateoptical system, the DLP9500UV can be used to modulate the amplitude,direction, and/or phase of incoming light.
Electrically, the DLP9500UV consists of a two-dimensional array of 1-bit CMOS memorycells, organized in a grid of 1920 memory cell columns by 1080 memory cell rows. The CMOS memoryarray is addressed on a row-by-row basis, over four 16-bit LVDS DDR buses. Addressing is handled bya serial control bus. The specific CMOS memory access protocol is handled by the DLPC410 digitalcontroller.

RefFIT is a data analysis program written by dr. Alexey Kuzmenko using the input and feedback from many colleagues over many years. It is designed to fit optical spectra, such as reflectivity, transmission, ellipsometry and Kerr and Faraday rotation using the Drude-Lorentz, Fano, Tauc-Lorentz and many other dielectric-function models. Currently the library includes more than 50 models. In addition to the rich model library, RefFIT allows you to apply a model-independent Kramers-Kronig analysis to virtually any type of optical spectra, using an original Kramers-Kronig constrained variational technique.
RefFIT has a powerful and fast fitting engine based on a modified Levenberg-Marquardt algorithm, a broad collection of proven physical models and a unique user-friendly interface. It allows you fitting manually or automatically several datasets of different type and using different models simultaneously while seeing on your screen precisely what you are doing.
Our users include physicists, material scientists, chemists, optics engineers, biologists and even computer-game designers. Also teachers use RefFIT in their courses: students can not only study the optical properties of materials, they themselves can play, model and fit as well.

Effect of Femtosecond Laser Treatment on Rice Seed Germination and Seedling Growth
The rice seeds of Longdao No.5 were selected as experimental materials.The seeds of Longdao No.5 were exposed by femtosecond laser at the wavelength of 800 nm,spot radius of 2 mm,power 650 mW and frequency of 1 000 Hz for 3 s,5 s,7 s,9 s,11 s and 13 s,separately.The effect of femtosecond laser irradiation on rice seed germination and seedling growth were studied.The results showed that the germination and the seedling growth of rice were stimulated by exposing the rice seeds with femtosecond laser.3～9 s femtosecond laser irradiation increased the rice germinating viability and germination rate.The inhibition of sprouting happened with the 11～13 s femtosecond laser irradiation.The height of the rice plant was increased by exposing the rice seeds especially when the seeds were exposed for 11 s and 13 s.The chlorophyll content,the POD activity increased and the SOD activity decreased after the irradiation treatment.
Parsnips and Celery are cool area crops suited to northern Europe. These are not mediterranean crops. Coriander has special uses as in vertical farming and is much used by curry houses and ethnic restaurants like Mexican and Middle Eastern. Coriander is hardy and can be grown outside as a field crop for most of the year.
Seeds were exposed to He–Ne (632.8 nm) red laser, Nd:YAG second-harmonic-generation (532 nm) green laser, and diode (410 nm) blue laser. Four different exposure times (45, 65, 85, and 105 s) with different intensity (2 and 4 mW/cm2), for each laser were tested. Phenology and yield components (plant height, leaf area, number of rows per ear, seed yield, harvest index, yield efficiency, and grain weight) were determined. The experiment was conducted in a randomized complete block design with three replications. Plant height was found comparatively high in blue laser light—211 cm at 85 s. Blue and green laser lights showed significant increases in the number of rows per ear to 39.1 at 85 s and 45 at 65 s, respectively, compared to the control of 36 rows/ear. The order of seed yield was blue (7003.4 kg/ha) > green (6667.8 kg/ha) > red (6568.01 t/ha) based on different exposure times of 85 s, 85 s, and 105 s, respectively, compared to the control of 6.9 kg/ha. The findings indicate the possibility of using blue laser light to manipulate the growth and yield of maize.
In this study, the effect of the plasma treatment on corn seeds is investigated. Corn seeds were treated uniformly without burning or blackening by three kinds of plasma apparatus: RF plasma in vacuum, microwave-driven atmospheric-pressure plasma, DBD atmospheric-pressure plasma, and two other treatments: vacuum exposure only, and using plasma-activated water in the seed coating process, to investigate growth rate changes under realistic conditions. Each treatment was performed on a total of 1512 corn seeds. Seeds from each experimental condition were treated with the recommended rate of Poncho/VOTiVO with Acceleron, a commercial biological seed treatment that helps to protect the seeds from fungus, insects, and nematodes after planting. The 1512 seeds were divided evenly into three replications with 84 seeds planted for each replication at six unique locations across central Illinois. The results for germination, growth, and product yield over the 2017 growing season is presented. Overall no statistically significant difference in the yield of corn harvested was found between the control and any of the five treatments. This is likely due to the already near-100% germination rate of the corn hybrid used in the study and the use of the Poncho/VOTiVO protective coating on every sample.
