“…Our results are in agreement with others studies (Rorat et al, 2001;Savitch et al, 2002;Hu et al, 2006) in which significant differences in ФPSII were related with different tolerance to photoinhibition.…”

“…On the other hand, neither Fv/Fm ( Figure 2C) or NPQ ( Figure 2D) were affected in both species. These results are in agreement with previous observations (Tapia, 2005;Hu et al, 2006) in which the depression in ФPSII was driven primarily by qP, not Fv/Fm, suggesting that the photo-oxidationinduced decline of ФPSII was due to down-regulation of processes such as C fixation (Hu et al, 2006). Thus, ours results gives an indication about the efficiency of S. chilense to use light for photochemistry.…”

Simultaneous exposition to low temperature and high light radiation cause photoinhibition of photosynthetic apparatus, affecting the productivity and geographical distribution of agricultural crops. In several Solanaceous species, tolerance to low temperature stress in combination with high light has been associated with some stimulation in non-photochemical quenching (NPQ), which involved reorganization in light-harvesting complex (LHC) proteins. To study photosynthetic performance in Solanum lycopersicum L. and S. chilense (Dunal) Reiche, and to investigate transcriptional regulation of genes encoding LHC proteins and their involvement in the NPQ, plants of both species were exposed to low temperature (4 °C) and high light radiation (1300 µmol m -2 s -1 ). Lipid peroxidation, photochemical efficiency, and changes in xanthophyll cycle pigments were measured. The results presented here indicate that S. chilense showed higher tolerance to photoinhibition than S. lycopersicum under low-temperature and high light conditions, increasing light-energy consumption in photochemical processes by increasing photosynthetic capacity as indicated by photochemical quenching (qP) and relative electron transport rate (ETR) parameters. The contribution of light-harvesting chlorophyll a/b binding (LHC) protein was not related to dissipate excess excitation energy as heat (NPQ), but rather with the antioxidant function attributable to zeaxanthin as indicated by the amount of peroxidized lipids in S. chilense. We suggest that the differential expression of Lhca1 transcripts, with zeaxanthin binding sites could contribute to the greater tolerance of S. chilense to photoxidative stress.

“…Heuvelink (1989) indicates that in young plants, temperature controls the relative growth rate (RGR) of leaves, by acting on the leaf area ratio (LAR) (leaf area of a plant by its dry weight unit, cm 2 g -1 ), thus increasing interception of solar radiation. The combination of low radiation and sub-optimal temperature was studied by Hu et al (2006) with tomato varieties for open-field and greenhouse cultivation. Plants with 3 to 14 true leaves were exposed to cold stress, obtaining higher values of net photosynthesis in the greenhouse varieties; the authors point out that greenhouse varieties are cultivated in cold seasons with low luminosity, which allows them to recover from stress.…”

Chilling tolerance is a desirable trait in commercial tomato varieties, in order to extend the growing season and geographic range. Two Nearly Isogenic Lines (NILs) with introgressions in chromosome 2 and 3 of Solanum habrochaites S. Knapp & D.M. Spooner, a cold-resistant wild tomato, were evaluated in the field. Four plantings were established between 21 August and 2 October 2006 (day 232 and 274). Throughout the experiment the heat sum was interpreted using air temperature to calculate growing degree days (base 12 °C) and chilling hours (below 12 °C), with the daily light integral calculated as global solar radiation. The relative post-transplant growth rate, fruit set and yield, were evaluated over two successive 10-d periods. Chilling tolerance is expressed under high radiation and low temperature conditions, which occurred during the 10-d post-transplant evaluation period beginning on day 257, when both NILs achieved a leaf area growth rate 1.7 times higher than the control plants. During the second evaluation period, 10-20 d post-transplant, both NILs grew on average, 1.4 times more than the control. There were no significant differences in earliness or fruit set. These NILs should not be used as a direct source to obtain chilling tolerant varieties, because of the low fruit set, 84% lower in LA3921 than the control, probably due to linkage drag and poor environmental adaptability in both lines.

“…The summer energetic availability advances high productive tropical pasture species, such as Pennisetum, Paspalum, Brachiaria [1] [2] [3], to growth in subtropical area [4] [5], particular grass C4 plants, which prefer to warmer climates because their physiological processes are adversely affected by low temperature [6] [7]. Winter-spring low temperature is one of the most factors to limit the growth and productivity of plants [8] [9] and limit the geographical locations where cultivated species can be grown [10].…”

Forage production and quality of five tropical grass accessions (Guimu-1 hybrid elephant grass (PG1), Mulato II (M II), Ubon paspalum (PU), hybrid elephant grass (PH) and Reyan 11 paspalum (PR11)) and two tropical legume accessions (Reyan 5 stylo (SR5) and Ubon stylo (SU)) were evaluated in a field experiment in a subtropical area with hot summers and cold winters in Guangxi, China. Three forage stubble cover managements: no cover (CK), dry mass cover (MC) and plastic cover (PC) were applied at the end of the summer period to evaluate cold tolerance and accession survival over the winter. Photosynthesis measurements were taken from the forages in mid-summer. The results showed that PG1 accession produced significantly higher dry matter yields (67.0 t·ha −1 ) than the other grass and legume accessions. Legume accessions SU and SR5 produced much less dry matter (6.4 -7.2 t·ha −1 ) compared to the grasses. M II, PU and PR11 contained the largest proportion of leaf. PG1 and PH showed good cold tolerance (survival rate >85%) under −1˚C conditions without any cover management. PR11 had better cold tolerance than PU. M II exhibited very poor winter survival under no cover and with massive cover, and only survived well under plastic cover. The two stylo accessions died completely under all winter cover management treatments. In the growing season, under a given photosynthesis photon flux density (PPFD) = 1500 μmol m . Though these 7 tropical accessions yielded high production in the grow season, stylo and M II are sensitive to cold in subtropical region of Guangxi. The result suggests that PG1 and PU are good accessions and can be used as productive perennial pasture, while stylo and M II are How to cite this paper:
