“…Alternatively this reduction in stem length may be the result of the different greenhouse environmental conditions that the crop was grown under following each of the storage durations. Internode and stem length increase with increasing daily air temperature differential (Moe & Heins 1990). The temperature differential decreased from the first to the third planting and increased slightly between the third and fourth planting in a similar pattern to stem length.…”

Temperatures of 3-5°C were suitable for the long-term storage of sandersonia tubers. Tubers sprouted during storage at 10°C, but no sprouting occurred with up to 202 days of storage at 3-5°C. Tuber viability and subsequent sprouting were less after storage at 1°C than following 3-5°C storage temperatures. Sprouting temperatures of 20-26°C gave high sprouting percentages following long-term storage. Tubers failed to sprout at 35°C and sprouting percentages were lower at 30°C than 20-25°C following longer storage durations (>60 days). Storage duration, storage temperatures, and sprouting temperatures influenced the time from storage removal to sprouting, storage removal to stem harvest, stem size, and daughter tuber weight. Stem length declined with increasing storage duration of 110-171 days, but was slightly greater after 202 days of storage than after 171 days. Possible reasons for these plant responses are outlined. Daughter tuber weight declined with storage duration and was less following a sprouting temperature of 20°C than 23-26°C.

“…The reduction in time from sprouting to shoot emergence and from shoot emergence to stem harvest may have been because of warmer soil and air temperatures in the later plantings. Mean temperature has only a small effect on stem length but influences the growth rate (Moe & Heins 1990).…”

“…Two main light qualities were detected by pigment systems in plants, phytochrome and blueabsorbing pigments (BAPs). Phytochrome was most sensitive to red light and far-red light, while BAPs are influenced by B and ultraviolet-A (UV-A) light spectrum (Moe and Heins, 1990). Both light quantity of photon flux and wavelength were very important for plant growth and development (Moshe and Dalia, 2007).…”

The objective of the present study was to evaluate the effects of different light emitting diodes (LEDs) on growth, photosynthetic characteristic and chloroplast ultrastructure of upland cotton (Gossypium hirsutum L.) seedlings. Seedlings of the cultivar Sumian 22 were grown under seven different lights including blue (B) plus red (R) LEDs BR (1:8, 1:3, 1:1, 3:1), B LEDs, R LEDs and fluorescent lamps (FL) with the 100 μ mol m -2 s -1 photosynthesis photon flux (PPF) and a 12 hour photoperiod for 40 days. Compared with FL, fresh mass, dry mass, root length, stem width, root activity, length of palisade tissue and stomatal frequencies were significantly greater as well as the thickest grana lamella in chloroplast in seedlings grown under BR1:8 LEDs; The chlorophyll a, chlorophyll b, total chlorophyll contents, photosynthetic rate, leaf thickness, spongy tissue length and stomatal areas were highest in seedlings under B LEDs; The stem length, leaf area, sucrose, soluble sugar and starch concentrations were highest as well as the greatest number and volume of starch grains in chloroplast in seedlings under R LEDs. It was suggested that BR1:8 LEDs might be used as a primary light for the cultivation of upland cotton seedlings under controlled conditions.

“…The flowers apparently became a progressively larger sink for dry matter during development (Cockshull and Hughes 1968) and newly produced dry matter as well as reallocation from other plant parts (Fig. 3) (Erwin et al 1989;Moe and Heins 1990) including C. monfolium Karlsson and Heins 1986 Although plant dry matter at flowering varied from 3.6 to l'l .2 g and the number of SD to flower from 60 to 120 (Table 1), dry matter accumulation in roots, stems and leaves on a relative scale was similar.…”

. Chrysanthemum dry matter partitioning patterns along irradiance and temperature gradients. pan.^J. Plant Sci. 72: 307 316. The influence of photosynthetic photon flux (PPF,.6 mol d -' m -') and day (DT) and night (NT) temperature (10-30'C) on dry matter accumulation and partitioning was studied in Chrysanthemum morifolium Ramat. 'Bright Golden Anne'. Total plant dry matter varied from 3.6 to 17.2 g at flowering. Plants with the greatest dry matter were from treatments with high PPF levels and temperatures. Accumulation of dry matter in roots, stems, leaves and flowers examined on a normalized time and normalized dry matter basis showed similar trends independent of DT, NT and PPF during development. Accumulated dry matter in roots, stems and leaves increased to a maximum and then decreased as the flowers were developing.Maximum leaf, root and stem dry matter was reached at 81, 85 and9l%, respectively, of required time from staft of short days (SD) to flower. Proportion root dry matter increased and proportion leaf dry matter decreased in the plants as PPF
