Herbaceous plants stems

inflorescence

Why does the biomass of herbaceous plants increase during spring?

please scientifically explained answers.
i would also like to get some links for further research.
thank you in advance.

Herbaceous perrennial plants die down to their crown tissue and underground organs that are protected in the ground. Each spring they must regrow stems and leaves from dormant buds. Woody perennials retain an above ground scaffolding of stems with dormant apical buds. In these plants the leaves are temporary but there are adventitious buds to replace lost stems following fire or severe freezing damage.

The plants mobilize stored starch to begin the process of apical growth of new stems & leaves or new leaves as soon as the increasing temperatures and sunlight are sufficient to trigger the process. Stem respiration increases with spring bud break over several weeks as cells grow using winter stores for energy. This supports leaf growth until leaves are 20 – 40 % grown. At this point net photosynthesis is positive and the plant is once more supporting itself on fresh photosynthate rather than stored starch.

Herbaceous perennials enter the maximum growth state in spring and stored resources are dedicated to bud break then stem and first leaf growth. After leaf-out the plant slows to normal growth state and resources are allocated to stem and root growth until it is time to begin reproductive inflorescence growth and seed set.

You were correct in eliminating some of the leaf surface and making a shallow wound in the base of the stem.
For soft wood stem cuttings one usually makes a clean cut just below a node in the stem and then a one inch sliced wound .
You may not have lost the plant. Roots may form this autumn.
The leaves may have fallen from drying out or perhaps a fungus formed in the soil
With evergreen leaf cuttings I sometimes will put plastic over the cuttings to keep the humidity up .
Environmental control such as stress, too much water, not enough light or a soil fungus appearance are all plausible reasons for the leaf drop

DALY: Use care when planting around septic drainfields  — Gwinnettdailypost.com
Shallow rooted annual and perennial herbaceous plants can be planted closer to the drain fields since they do not have invasive roots. Turfgrass can be grown over the drain field and is beneficial since it helps hold the soil in place.
