“…This was consistent with previous research into summer maize, which would give priority to dividing water to roots to form larger roots when water was deficient; as a result, the root biomass increased and then transported as much nutrients to the ground as possible [ 42 ], but also corresponded with previous findings that evergreens and Molinia distributed relatively more biomass to the roots at low nutrient supply, thus increasing their competitive ability for belowground resources [ 43 ]. Additionally, adjustment of the above-ground biomass allocation was one of the important components of the adaptive strategies for plant growth [ 44 ]. In our findings, stem biomass in two ploidy levels always kept the largest allocation percentage, and that of T4 and T17 presented an increasing trend under stress, suggesting that stems were the important water storage organs of plants.…”

As one of the most influential environmental factors, drought stress greatly impacts the development and production of plants. Triploid-induced Passiflora edulis Sims ‘Mantianxing’ is an important new cultivar for multi-resistance variety selective breeding, which is one of the P. edulis breeding essential targets. However, the performance of triploid ‘Mantianxing’ under drought stress is unknown. In order to study the drought resistance of triploid ‘Mantianxing’, our study compared drought-related indicators in diploids and triploids under natural drought experiments, including morphological, physiological, and biochemical characteristics. Results showed that triploid P. edulis ‘Mantianxing’ showed variable responses to drought treatment. Compared with diploids, triploids showed higher photosynthesis and chlorophyll fluorescence, osmotic adjustment substances, and antioxidant enzyme activity under drought stress and faster chlorophyll biosynthesis and growth recovery after rewatering. Generally speaking, these results indicate that the drought resistance of triploid P. edulis is superior to diploid. This study provides scientific information for breeding stress tolerance variety of P. edulis ‘Mantianxing’ new cultivar.

“…Plants typically develop different biomass accumulation and allocation patterns and phenotypic plasticity characteristics, indicative of their significant adaptive regulation of phenotypic plasticity and biomass allocation strategies in different regions. Moreover, in different regions, plants have been shown to alter their investment in different components (organs) to adapt to environmental variation, which is reflected in their ability to acquire available environmental resources (e.g., sunlight, water, and nutrients) and their ecological adaptive strategies to environmental change [1]. Temperature has a fundamental effect on plant physiology and ecosystem metabolism at a local scale [2].…”

Bamboo is one of the most important forest resources, widely distributed throughout subtropical and tropical regions. Many studies have focused on bamboo functional trait variation under different environmental conditions. However, the functional feature response of bamboo components to regional and climatic factors and associated coupling effects are less known. This study analyzed phenotypic plasticity and biomass accumulation and allocation processes in aboveground Pleioblastus amarus components (i.e., the culm, branch, and leaf) with principal component analysis (PCA) and partial least squares structural equation modeling (PLS-SEM) in three regions of China. Consequently, obvious regional differences were observed in phenotypic plasticity, biomass accumulation, and allocation processes. With decreasing latitude and increasing longitude, the internode length was longer for larger and rounder bamboo and the culm wall was thinner at a lower relative total height. Moreover, the number and width of crowns became greater, thicker, and longer. With increasing latitude, branch and leaf biomass decreased significantly, while biomass allocation to bamboo branches and leaves first decreased before increasing. And with increasing longitude, culm and total biomass reduced significantly along with culm biomass allocation, while total branch and leaf biomass allocation gradually decreased. Clearly, climatic factors, such as maximum temperature and mean annual temperature, directly affected the phenotypic plasticity of P. amarus and its associative biomass accumulation. Meanwhile, soil factors (i.e., soil available phosphorus, capillary porosity, field water holding capacity, and total nitrogen content) caused significant variation in phenotypic plasticity, indirectly affecting plant biomass accumulation and allocation processes. Collectively, these initial findings indicate that low-latitude and high-longitude stands promoted greater morphogenesis and more efficient biomass accumulation and allocation in aboveground P. amarus components, exhibiting superior morpho-plasticity and higher stand productivity. This study clarified regional differences in P. amarus morphological phenotypic plasticity and biomass accumulation and allocation. It is expected that the results can aid in provenance selection and the directional cultivation of high-yield bamboo stands.
