“…Present study showed 9.2%, 36.7% and 40% lower transpiration rate, stomatal conductance and water use efficiency in control than 2.6 mg B respectively. Our results validate the findings of [52] who concluded that significant decreased in stomatal conductance, photosynthetic rate and transpiration rate in the functional leaves of cotton after the formation of brown rings on the petiole are due to destruction of vascular bundle of petiole. [53] also reported that B deficiency deformate the phloem sieve which affects the transport of carbohydrates, water and nutrients that results in reduction of stomatal conductance and transpiration rate.…”

20Boron (B) is deficient in the calcareous, Typic Haplocambid soils of cotton growing 21 belt of Pakistan, and thus is a vital reason for less cotton yield in the region. In order to 22 investigate the growth and quality alterations associated with soil applied B on cotton (cv. 23 CIM-616 and CIM-600) an experiment was conducted. Boron was applied at 0.00, 2.60, 5.52, 24 7.78 and 10.04 mg B kg -1 of soil using borax (Na 2 B 4 O 7 .10H 2 O), in a complete randomized 25 design with factorial arrangement with four replications. Results revealed that soil applied B 26 @ 2.60 mg B kg -1 of soil significantly (P≤0.05) improved cotton growth, yield, quality and B 27 distribution among different parts. Different growth and yield parameters like plant height, 28 leaf area, number of bolls, boll size and weight, seed cotton yield, photosynthesis, transpiration 29 rate, stomatal conductance, water use efficiency, GOT, staple length and fiber fineness and 30 strength except B uptake by roots, seed, leaves and stalk plant body which was significantly 31 increased with B (10.04 mg B kg -1 ) in both cultivars of cotton, but the degree of effects was 32 varied between cultivars. The results indicated that studied traits of both cultivars were 33 significantly (P≤0.05) decreased in B-deficient stressed treatments. Between hybrids, CIM-34 600 produced significantly (P≤0.05) maximum recorded parameters under 2.60 mg B kg -1 35 application compared than CIM-616. Our findings confirm that the adequate level of B (2.60 36 mg B kg -1 ) had pronounced effects on various growth, yield, physiological and fiber quality 37 associated traits, as compared to B uptake traits of cotton cultivars.38 39 40 fiber quality are serious problems in cotton production [2]. Certain factors are particular for 44 these problems, include poor fertilization especially lack of certain micronutrients like boron 45 (B), which could improve the cotton yield and quality [3]; [4]. Boron deficiency has been 46 prominent in cotton growing regions of the world including Pakistan, where 50% cotton 47 growing area is deficient in B [5]; [6] and [7]. Its deficiency is common in tropical soils, 48 where organic matter and clay content are lower [8] which are responsible for its leach 49 down through the soil profile [9]; [10]. Degree of B adsorption onto the soil surfaces depend 50 on the soil characteristics such as structure, pH, organic matter and clay content, iron and 51 aluminum oxide and hydroxyl content and salinity [11]; [12]. However, its balanced 52 application needs more consideration due to its narrow range between deficiency and 53 toxicity which significantly retard the cotton production and physiological traits without 54 any visible symptoms [13]. Moreover, B use improvement is difficult due to its low 55 mobility in phloem vessels and result in low degree of its reutilization in cotton plant [14]; 56 [15]. Due to low mobility in phloem vessels the required concentration of photosynthate and 57 carbohydrate are not reached from leaves to fruits [15...

“…Effects of seed size (mass) on germination and seedling establishment of perennial plants in grassland 1 and forest 2 ecosystems have been well understood. Seed size is correlated with various seed functional traits, and often affects the timing of germination, germination capacity, offspring seedling establishment, and diversity and composition of community 1 , 3 , 4 .…”

Seed nutrients reserves have direct relationship with seed functional traits and influence offspring performance. Effects of plant density, foliage boron (B) nutrition and mepiquat chloride (MC) growth regulation on seed nutrients reserves, seed mass and production, and emergence and offspring growth traits of cotton were studied in two years field experiment. Seed nutrients reserves and seed mass were decreased at higher maternal plant density relative to lower plant density with concomitant decrease in emergence and offspring seedling growth. However, maternal foliage B nutrition and MC growth regulation enhanced seed nutrients reserves, seed mass, emergence and offspring seedling growth performance. There was a significant positive relationship between seed mass and seed nutrients reserves indicating that changes in nutrient availability/uptake in response to maternal ecological factors determine variation in seed functional traits. Nonetheless, seed mass was positively correlated with emergence percentage and negatively with emergence timing. Furthermore, variation in offspring seedling growth traits with seed mass indicated the significance of initial seed nutrients reserves for early seedling vigour and establishment. In conclusion, lower maternal plant density, B nutrition and MC growth regulation ensued in higher emergence and offspring seedling growth of cotton because of higher seed nutrient reserves and seed mass.

“…Previous studies have focused on above-and below-ground net primary production, plant diversity, and carbon cycling responses to N addition in juvenile and adult stage plants (Du et al, 2018;Humbert, Dwyer, Andrey, & Arlettaz, 2016;Pakeman et al, 2016;Soons et al, 2016;Yang et al, 2012). Many studies have shown that long-term N addition affects offspring performance, such as seed germination, seedling establishment, and soil seed banks (Basto et al, 2015;Li, Hou, Song, Yang, & Li, 2017;Xia & Wan, 2013). The response of soil seed banks to long-term N deposition is a major concern as they contribute to maintain in the plant community (Royo & Ristau, 2013).…”

Seed germination and seedling establishment play an important role in driving the responses of plant community structure and function to global change. Nitrogen (N) deposition is one of the driving factors of global change, which often leads to a loss in species richness in grassland ecosystems. However, how seed germination responds to N addition remains unclear. A pot incubation test was conducted in a semi‐arid grassland in the Mongolian Plateau, Northern China, to investigate the effect of N addition (0, 5, 10, 20, 40, and 80 g N/m 2 ) on seed germination from May to October 2016. Twenty species germinated under all treatments; however, the responses of the 20 species to N addition were different. The densities of Stipa krylovii , Leymus chinensis , and Artemisia frigida, which are the dominant species in this temperate steppe, decreased significantly as the amount of N addition. Moreover, N addition significantly suppressed seedling densities of the community, perennial forbs, perennial grasses, and annuals and biennials. Furthermore, species richness of the community, perennial forbs, and annuals and biennials decreased sharply with increasing N addition level, but perennial grass species richness did not change. The Shannon–Wiener diversity index also decreased as the amount of N addition increased. Our results suggest that N enrichment plays an important role in the seed germination stage and decreases supplements of seedlings to adult plants. These findings may help explain the causes of species loss by atmospheric N deposition in grassland ecosystems.
