“…These adaptations should improve the anchorage of plants. Finally, it should also be pointed out that other traits such as root stiffness (Crook and Ennos 1993;Goodman et al 2001;Mickovski et al 2007), changes in cell wall properties, i.e. lignin (Scippa et al 2006) and cellulose (Genet et al 2005), and root system asymmetry (Nicoll and Ray 1996;Mickovski and Ennos 2003) can also play a role in plant anchorage.…”

In marly catchments of the French Southern Alps, soils are subjected to harsh water erosion that can result in concentrated flows uprooting small plants. Evaluating and predicting plant resistance to uprooting from simple plant traits is therefore highly important so that the most efficient plant strategy for future restoration of eroded slopes can be defined. Twelve species growing on marly land were studied. For each species, in-situ lateral uprooting tests were conducted and morphological plant traits were measured on small plants at the early stages of their development. The results show that maximum uprooting force was most positively correlated with stem basal diameter. Resistance to uprooting depends on a combination of several traits. Tap root length, the proportion of fine lateral roots and root topology were the best predictors of anchorage strength.

“…The plant achieves greater lodging risk through increased growth and developing week leverage to support the plants. Mechanical lodging is triggered by strong wind and/or rain and can be intensified by an attack of insects or fungal pathogens [Pinthus 1973, Hoshikawa and Wang 1990, Crook and Ennos 1993. Lodging is generally more common on heavy soils because of their relatively high water and nutrient holding capacity.…”

INTRODUCTION OF ENDEMIC Allium tuncelianum KOLLMAN FROM HOT AND TEMPERATE CLIMATE TO SEMI-ARID CLIMATIC CONDITIONS

Allium tuncelianum (Tunceli garlic) is a single cloved important threatened endemic geophyte of high commercial importance that grows scattered on hot temperate mountains under oak trees in the eastern Turkish province of Tunceli. Tunceli garlic is used diversely in salads, foods and in pharmaceutical industry. They also offer a rich choice for their use in rock gardens and landscaping. There is need to develop appropriate agronomic practices for its propagation outside its habitat. In line with this objective, the study optimized planting time (1 st September, 15 th September and 1 st October) of A. tuncelianum on mild alkaline soils under semi-arid climatic conditions of Diyarbakir, Turkey. The results of the study showed positive gain in morphological characteristics such that bulb diameter of the plants changed between 3.43 to 4.60 cm, bulb circumference ranged 14.4 to 16.1 cm and bulb weight had a range of 35.9 and 46.3 g. These results underscore positive effects of early and mid September plantings of Tunceli garlic outside its habitat under semi-arid conditions for economic production with early harvest.

“…The index of lodging risk (ILR) was calculated by the formula ILR = M/S s , where M (g cm) is the self-weight mass moment generated by a single tiller and is the product of height (H) and fresh weight (FW) from the potential breaking point to the top of the tiller. The FW was measured using a keen knife cut off breaking point after observed F max and entire fresh weight as soon as possible [6].…”

“…Rice is one of the most important staple foods for human nutrition [5], and taking advantage of elevated [CO 2 ] for increasing yield is essential to ensure food security. Lodging, a frequent field occurrence, is a major cause of cereal yield loss and quality reduction [6], because it directly decreases canopy photosynthesis and disturbs the translocation of C and N within shoot and root [7,8]. Setter et al [9] demonstrated that in rice, yield losses can be as much as 1% for every 2% of stem that has lodged.…”

Effects of elevated [CO2] on stem and root lodging among rice cultivars

et al. 2013

Studies showed that elevated [CO 2 ] would improve photosynthetic rates and enhance yields of rice; however, few studies have focused on the response of rice lodging, which is a major cause of cereal yield loss and quality reduction, under elevated [CO 2 ]. In this study, we examined the effects of elevated [CO 2 ] on stem and root lodging using 4 rice cultivars (86Y8, japonica hybrid; LYP9, 2-line indica hybrid; variety 9311, type of indica inbred rice, and SY63, 3-line indica hybrid) grown under two [CO 2 ] levels: 400 and 680 µmol mol -1 . Our results indicated that under elevated [CO 2 ], the stem-lodging risk (SLR) of 9311 decreased, while in SY63 the SLR increased, 86Y8 and LYP9 were not significantly affected; the risk of root lodging was reduced for all cultivars, because root biomass (instead of root number) and bending strength were increased significantly, and then the increase of anti-lodging ability is far higher than that of self-weight mass moment for all cultivars. These findings suggested that higher [CO 2 , because it directly decreases canopy photosynthesis and disturbs the translocation of C and N within shoot and root [7,8]. Setter et al.[9] demonstrated that in rice, yield losses can be as much as 1% for every 2% of stem that has lodged. Hence, if lodging risk is increased in rice under elevated [CO 2 ], the potential for increases in yield would be limited [9]. A better understanding of the mechanisms for lodging response will be helpful to reduce the incidence of lodging under elevated [CO 2 ] by enabling plant breeders to choose those characteristics in rice which are expected to increase lodging resistance, and increase food security. Lodging is accelerated by heavier panicles and longer culms, which increases the plant's mass moment (mass multiplied by distance from the point of attachment). Elevated [CO 2 ] has been shown to increase the rate of grain filling and the final weight of the panicles as a result of increased panicle size [3,4]. During the grain-filling period, panicle weight under
