“…Scott and Schrader (1947) found that boron concentrations in mature grape leaves declined when boron was absent from the root environment, suggesting remobilization of boron from leaves. Remobilization of boron is its movement from one organ to supply another organ or tissue in the plant.…”

The question of boron mobility and re-use in planits has not been adequately investigated. It is often dismissed with the statenment that a continuous supply of boron is necessary during growth because boron cannot be stored and re-use(l. However, there is evidence that boron is not entirely immobile, although re-use has not been (lefinitely establishe(l. Eaton, McCallum, and Mlayhugh (3) showed that, under conditions of excess boron, stone fruit trees translocate boron to the fruit an(d that higlh concentrations can accumulate there -while only moderate concentrations remain in the leaves. Scott and Schrader (8) showed that the concentration of boron in older leaves of the grape plant (lecrease(l after the source in the root media hadl been removed. They On the (late designatedl for Period 1 the nutrient solution was (lumped an(l the gravel wvas flushed four timles with (listillech water and nutrient without boron then provided. At the end of each of 12 assigned intervals, the plants of a particular group were cut at the cotyledonary no(le and the fresh weight was taken. The leaves w\ere then strippedl from the stem and numbered consecuttively from the base of the plant. Leaves

“…Because B is not readily mobile in the phloem of most species, foliar application is only effective when sprayed directly on B deficient tissue (Brown and Hu, 1996). For many years B was thought to be phloem-immobile in all species, but in 1987 Shelp and co-workers showed that B can be redistributed via the phloem to young leaves, storage roots, and inflorescences in B-starved plants (Campbell, Miller, and Loneragan, 1975;Scott and Schrader, 1947;Benson, Degman, and Chmelir, 1961;Shelp and Shattuck, 1987a;Shelp and Shattuck, 1987b;Shelp, Shattuck, and Proctor, 1987). Shelp also suggests that at toxic levels, B can be transferred laterally between xylem elements to enhance B concentration in developing sinks leaves was re-distributed to other parts of the shoot and, particularly, to the fruit tissues.…”

Boron Deficiency and Chilling Injury Interactions in Tobacco Transplants Grown in the Float System

et al. 2008

OVERSTREET, LAURA FLINT. Boron Deficiency and Chilling Injury Interactions in Tobacco Transplants Grown in the Float System. (Under the direction of James W. Rideout.)Decades of agricultural research have failed to determine the precise mechanisms of infliction caused by the conditions of boron deficiency and chilling injury. Both conditions affect the quality and marketability of tobacco transplants grown in the float system. Interestingly, boron deficiency and chilling injury produce strikingly similar symptoms in young tobacco transplants; so similar, in fact, that they are often confused for one another. This has lead to severe boron toxicity when growers treated chilling injury as boron deficiency by applying boron to non-deficient float beds. The observation of nearly identical symptoms suggests that boron deficiency and chilling injury have interdependent effects on cell physiology and/or metabolism. Because little research has been conducted on tobacco transplants in the float system, two studies were conducted to determine general parameters for the boron deficiency threshold and effect of non-optimal temperatures and large day/night temperature differentials in this system. The boron deficiency study established that the deficiency threshold for transplants growing at 26/22º C is 10-20 µg B g -1 dry matter. These tissue levels occurred with solution concentrations of 0.19-1.9 µM B. The chilling injury study determined that root and shoot growth of flue-cured cultivars is near maximum at a constant 26/26º C temperature regime. Burley cultivars display a wider range of temperature tolerance, but in general constant day/night temperatures seem to provide the greatest shoot tissue accumulation.A reduction in night temperature resulted in decreased shoot growth in all cultivars. The chilling injury study also examined the effect of boron deficient conditions at each temperature treatment. In general, boron uptake declined at sub-optimal temperature regimes when supplied at concentrations sufficient for near-optimal temperatures. Shoot growth of flue-cured varieties at transplant stage was near maximal at a constant optimal day/night temperature regime (26/26º C) and adequate B concentrations. Sub-optimal temperatures may alter the boron deficiency threshold such that it decreases with decreasing temperatures or with stressful temperature differentials. This may be summarized in the following way: Temperature is the immediate limiting factor in tobacco transplant growth in the float system under conditions of sub-optimal temperatures and low B concentration, and B deficiency is an additional potential limiting factor.
