The high intensity (148–167 µmol/m 2 /s) was the most stressful and this was shown by dwarf plants, high wilting severity, low seedling vigor, late flowering, high percentage of empty pods, low pod number and low green canopy cover.

Why light levels are important for indoor plant growth

In addition, windows block a surprising amount of sunlight intensity compared with the same spot just outside the glass. Insect screening outside a window reduces intensity even more. Artificial lighting can either supplement natural light or be the sole light source for plants. Plants tolerate levels of light outside of their preferred range ...

Lighting for Indoor Plants | University of Maryland Extension

Indoor plants can be classified according to their light needs and tolerances — high, medium, or low. Select indoor plants according to the availability of natural light in your home. Otherwise, you will need to supplement light with artificial lighting. The three important aspects of indoor light are intensity, duration, and quality.

Light Stress In Plants: Identification & Treatment

In extreme cases, the high light intensity can cause severe enough damage to your plant that it eventually dies. It can also dry it out, making it difficult for the plant to undergo photosynthesis and proper growth. ... There are two distinct types of light stress in plants - high light stress and low light stress. Knowing the signs of both as ...

The Effect of Light Intensity on Plant Growth

The intensity of light available to a plant depends on both the strength of the light source at a particular time and the plant's exposure — that is, how close the plant is to the light source. The greater the …

Importance of Fluctuations in Light on Plant Photosynthetic …

Plants grown under high light intensity tend to develop thicker leaves than those grown under low light intensity (Evans and Poorter, 2001), which generally increases photosynthetic capacity per unit of area, improving the plant's ability to utilize light for carbon fixation (Terashima et al., 2006).

Light Intensity And Plant Growth – AccessibleGardens

Illuminance, or light intensity, is one of the most important factors in gardening. It affects plant growth, development, and yield. Too little light results in spindly, etiolated plants, while too much light can damage leaves and stunt growth. The ideal illuminance for most plants is between 500 and 2,000 lux (about 50 to 200 foot-candles).

Effect of light intensities on the photosynthesis, growth and …
