“THE EVIDENCE SUGGESTS the cooler temperatures running for 12 hours in every 24 under continuous light favours the metabolism of starch and sugars and translocation from the leaves and into the sinks.” Nights that are cooler than days favour phloem unloading (the transport of sugars out from the rapidly cooling leaves as darkness falls, followed by high rates of photosynthesis under warmer day temperatures). Some research studies have found that while continuous light under the same Tomatoes are another crop that often develop optimal warm temperatures that allow maximum rates of photosynthesis to occur damage symptoms under continuous light. can cause an overall reduction in growth due to assimilate build-up in the leaves. However, if the temperature is varied within a 24-hour period under the same continuous light, then growth benefits occur, and leaf damage is often prevented. This seems to be particularly beneficial for plants such as tomatoes and eggplant, which are prone to leaf injury under continuous light. It has been found that running temperatures of 26/16°C during a 12/12 hour period under continuous light as compared to a constant 23°C, the accumulation problems of sugars in the leaves was reduced and a higher rate of dry matter production and yields occurred. The evidence suggests the cooler temperatures running for 12 hours in every 24 under continuous light favours the metabolism of starch and sugars and translocation from the leaves and into the There could be significant growth advantages for crops with a high sink sinks. Studies have found that by varying the temperature demand grown under continuous light if techniques such as temperature within each 24-hour period, leaf injury in species prone to differences are used. damage under continuous light can be largely prevented. connect with cannabis helping you Maximum Yield Cannabis Digital Edition Subscriptions Are AVAILABLE NOW!
