The cultural practices within an orchard can materially affect root systems. In Ceylon , Gandhi cites a difference in citrus root distribution between irrigated areas and rainfall areas. However, when he grew grapefruit trees on Rough lemon with various degrees of cover crop the citrus roots would not compete with the cover crop. They either turned back …

Notably, although recruited from across the United States, nearly all participants were sheltering in place at the time of study enrollment due to the COVID-19 pandemic, which may have affected substance use patterns and mood as well as interest in a digital health intervention. Notably, however, alcohol sales in the United States increased during the COVID-19 …
Several trees of Webb Red Blush grapefruit on Tavares limequat also showed problems at the bud union.Olson postulated that since seedlings of calamondin, lemonquat, red grapefruit, and sweet orange grew normally, whereas certain budded combinations showed bud union crease, it would seem possible that the disorder was related to interaction between specific root stock and scion varieties. It …

Although knowledge of the art of budding, or grafting, goes back several millennia , it was only in the late 1800’s that budding of citrus became a general practice. The change was partly due to the introduction of superior varieties like the Washington navel orange, the Valencia orange and other named cultivars in which it …

To achieve this one needs a healthy, productive, long-lived tree. It is increasingly evident that one of the most basic factors in achieving this end is the use of the best available root stock. The initial cost of a good tree is no more than a bad tree; but it sure makes a difference over the …

Heterozygous recombinant BC6S1 individuals were allowed to self-pollinate and progeny were marker-selected to obtain homozygous BC6S2 sub-NILs. These plants underwent self-pollination to obtain ample BC6S3 seed for replicated field experiments. We evaluated 62 BC6S3 sub-NILs in the 2009 field experiments. In the 2010 field experiments, a subset of 42 of the 62 subNILs was evaluated to allow increased …
Further investigation found that transcription factor NAC4 acted downstream of AFB3 to regulate lateral root growth in response to nitrate, but did not affect primary root growth, indicating that AFB3 is likely to be involved in two dependent pathways to modulate root system architecture. Furthermore, AFB3 and NAC4 gene expression in response to nitrate treatment …
Similarly, lateral roots are associated with distinct microbial communities, differing between tips and bases, as well as between different types of lateral root . One trait influencing the differential microbial colonization of root tissues could be the differential exudation profiles of the distinct root parts. This is illustrated in the following example. Clusterroots are densely …

For many ENMs such as nanoceria,reactivity is highly size dependent. To accurately model material fates thus requires understanding how material surface properties affect integrity, how both change under varying environmental conditions such as pH, clay content,and organic matter content,and how surface properties and particle reactivity affect physicochemical processes that are parametrized in far-field models. This is especially true for …
In contrast, other plant species appeared to be unaffected by PPCP exposure. For instance, no significant change in growth rate was noticed after Phragmites australis was exposed to 60 μg L−1 ibuprofen . These findings imply that certain plants may have detoxification mechanisms contributing to their resilience to the stress of such xenobiotics. However, although an increasing …
